Education scholar Denise Pope has found that too much homework has negative effects on student well-being and behavioral engagement. (Image credit: L.A. Cicero)

A Stanford researcher found that too much homework can negatively affect kids, especially their lives away from school, where family, friends and activities matter.

“Our findings on the effects of homework challenge the traditional assumption that homework is inherently good,” wrote Denise Pope , a senior lecturer at the Stanford Graduate School of Education and a co-author of a study published in the Journal of Experimental Education .

The researchers used survey data to examine perceptions about homework, student well-being and behavioral engagement in a sample of 4,317 students from 10 high-performing high schools in upper-middle-class California communities. Along with the survey data, Pope and her colleagues used open-ended answers to explore the students’ views on homework.

Median household income exceeded $90,000 in these communities, and 93 percent of the students went on to college, either two-year or four-year.

Students in these schools average about 3.1 hours of homework each night.

“The findings address how current homework practices in privileged, high-performing schools sustain students’ advantage in competitive climates yet hinder learning, full engagement and well-being,” Pope wrote.

Pope and her colleagues found that too much homework can diminish its effectiveness and even be counterproductive. They cite prior research indicating that homework benefits plateau at about two hours per night, and that 90 minutes to two and a half hours is optimal for high school.

Their study found that too much homework is associated with:

* Greater stress: 56 percent of the students considered homework a primary source of stress, according to the survey data. Forty-three percent viewed tests as a primary stressor, while 33 percent put the pressure to get good grades in that category. Less than 1 percent of the students said homework was not a stressor.

* Reductions in health: In their open-ended answers, many students said their homework load led to sleep deprivation and other health problems. The researchers asked students whether they experienced health issues such as headaches, exhaustion, sleep deprivation, weight loss and stomach problems.

* Less time for friends, family and extracurricular pursuits: Both the survey data and student responses indicate that spending too much time on homework meant that students were “not meeting their developmental needs or cultivating other critical life skills,” according to the researchers. Students were more likely to drop activities, not see friends or family, and not pursue hobbies they enjoy.

A balancing act

The results offer empirical evidence that many students struggle to find balance between homework, extracurricular activities and social time, the researchers said. Many students felt forced or obligated to choose homework over developing other talents or skills.

Also, there was no relationship between the time spent on homework and how much the student enjoyed it. The research quoted students as saying they often do homework they see as “pointless” or “mindless” in order to keep their grades up.

“This kind of busy work, by its very nature, discourages learning and instead promotes doing homework simply to get points,” Pope said.

She said the research calls into question the value of assigning large amounts of homework in high-performing schools. Homework should not be simply assigned as a routine practice, she said.

“Rather, any homework assigned should have a purpose and benefit, and it should be designed to cultivate learning and development,” wrote Pope.

High-performing paradox

In places where students attend high-performing schools, too much homework can reduce their time to foster skills in the area of personal responsibility, the researchers concluded. “Young people are spending more time alone,” they wrote, “which means less time for family and fewer opportunities to engage in their communities.”

Student perspectives

The researchers say that while their open-ended or “self-reporting” methodology to gauge student concerns about homework may have limitations – some might regard it as an opportunity for “typical adolescent complaining” – it was important to learn firsthand what the students believe.

The paper was co-authored by Mollie Galloway from Lewis and Clark College and Jerusha Conner from Villanova University.

Does homework still have value? A Johns Hopkins education expert weighs in

Joyce epstein, co-director of the center on school, family, and community partnerships, discusses why homework is essential, how to maximize its benefit to learners, and what the 'no-homework' approach gets wrong.

By Vicky Hallett

The necessity of homework has been a subject of debate since at least as far back as the 1890s, according to Joyce L. Epstein , co-director of the Center on School, Family, and Community Partnerships at Johns Hopkins University. "It's always been the case that parents, kids—and sometimes teachers, too—wonder if this is just busy work," Epstein says.

But after decades of researching how to improve schools, the professor in the Johns Hopkins School of Education remains certain that homework is essential—as long as the teachers have done their homework, too. The National Network of Partnership Schools , which she founded in 1995 to advise schools and districts on ways to improve comprehensive programs of family engagement, has developed hundreds of improved homework ideas through its Teachers Involve Parents in Schoolwork program. For an English class, a student might interview a parent on popular hairstyles from their youth and write about the differences between then and now. Or for science class, a family could identify forms of matter over the dinner table, labeling foods as liquids or solids. These innovative and interactive assignments not only reinforce concepts from the classroom but also foster creativity, spark discussions, and boost student motivation.

"We're not trying to eliminate homework procedures, but expand and enrich them," says Epstein, who is packing this research into a forthcoming book on the purposes and designs of homework. In the meantime, the Hub couldn't wait to ask her some questions:

What kind of homework training do teachers typically get?

Future teachers and administrators really have little formal training on how to design homework before they assign it. This means that most just repeat what their teachers did, or they follow textbook suggestions at the end of units. For example, future teachers are well prepared to teach reading and literacy skills at each grade level, and they continue to learn to improve their teaching of reading in ongoing in-service education. By contrast, most receive little or no training on the purposes and designs of homework in reading or other subjects. It is really important for future teachers to receive systematic training to understand that they have the power, opportunity, and obligation to design homework with a purpose.

Why do students need more interactive homework?

If homework assignments are always the same—10 math problems, six sentences with spelling words—homework can get boring and some kids just stop doing their assignments, especially in the middle and high school years. When we've asked teachers what's the best homework you've ever had or designed, invariably we hear examples of talking with a parent or grandparent or peer to share ideas. To be clear, parents should never be asked to "teach" seventh grade science or any other subject. Rather, teachers set up the homework assignments so that the student is in charge. It's always the student's homework. But a good activity can engage parents in a fun, collaborative way. Our data show that with "good" assignments, more kids finish their work, more kids interact with a family partner, and more parents say, "I learned what's happening in the curriculum." It all works around what the youngsters are learning.

Is family engagement really that important?

At Hopkins, I am part of the Center for Social Organization of Schools , a research center that studies how to improve many aspects of education to help all students do their best in school. One thing my colleagues and I realized was that we needed to look deeply into family and community engagement. There were so few references to this topic when we started that we had to build the field of study. When children go to school, their families "attend" with them whether a teacher can "see" the parents or not. So, family engagement is ever-present in the life of a school.

My daughter's elementary school doesn't assign homework until third grade. What's your take on "no homework" policies?

There are some parents, writers, and commentators who have argued against homework, especially for very young children. They suggest that children should have time to play after school. This, of course is true, but many kindergarten kids are excited to have homework like their older siblings. If they give homework, most teachers of young children make assignments very short—often following an informal rule of 10 minutes per grade level. "No homework" does not guarantee that all students will spend their free time in productive and imaginative play.

Some researchers and critics have consistently misinterpreted research findings. They have argued that homework should be assigned only at the high school level where data point to a strong connection of doing assignments with higher student achievement . However, as we discussed, some students stop doing homework. This leads, statistically, to results showing that doing homework or spending more minutes on homework is linked to higher student achievement. If slow or struggling students are not doing their assignments, they contribute to—or cause—this "result."

Teachers need to design homework that even struggling students want to do because it is interesting. Just about all students at any age level react positively to good assignments and will tell you so.

Did COVID change how schools and parents view homework?

Within 24 hours of the day school doors closed in March 2020, just about every school and district in the country figured out that teachers had to talk to and work with students' parents. This was not the same as homeschooling—teachers were still working hard to provide daily lessons. But if a child was learning at home in the living room, parents were more aware of what they were doing in school. One of the silver linings of COVID was that teachers reported that they gained a better understanding of their students' families. We collected wonderfully creative examples of activities from members of the National Network of Partnership Schools. I'm thinking of one art activity where every child talked with a parent about something that made their family unique. Then they drew their finding on a snowflake and returned it to share in class. In math, students talked with a parent about something the family liked so much that they could represent it 100 times. Conversations about schoolwork at home was the point.

How did you create so many homework activities via the Teachers Involve Parents in Schoolwork program?

We had several projects with educators to help them design interactive assignments, not just "do the next three examples on page 38." Teachers worked in teams to create TIPS activities, and then we turned their work into a standard TIPS format in math, reading/language arts, and science for grades K-8. Any teacher can use or adapt our prototypes to match their curricula.

Overall, we know that if future teachers and practicing educators were prepared to design homework assignments to meet specific purposes—including but not limited to interactive activities—more students would benefit from the important experience of doing their homework. And more parents would, indeed, be partners in education.

7 Research-Based Reasons Why Students Should Not Have Homework: Academic Insights, Opposing Perspectives & Alternatives

In recent years, the question of why students should not have homework has become a topic of intense debate among educators, parents, and students themselves. This discussion stems from a growing body of research that challenges the traditional view of homework as an essential component of academic success. The notion that homework is an integral part of learning is being reevaluated in light of new findings about its effectiveness and impact on students’ overall well-being.

The push against homework is not just about the hours spent on completing assignments; it’s about rethinking the role of education in fostering the well-rounded development of young individuals. Critics argue that homework, particularly in excessive amounts, can lead to negative outcomes such as stress, burnout, and a diminished love for learning. Moreover, it often disproportionately affects students from disadvantaged backgrounds, exacerbating educational inequities. The debate also highlights the importance of allowing children to have enough free time for play, exploration, and family interaction, which are crucial for their social and emotional development.

Checking 13yo’s math homework & I have just one question. I can catch mistakes & help her correct. But what do kids do when their parent isn’t an Algebra teacher? Answer: They get frustrated. Quit. Get a bad grade. Think they aren’t good at math. How is homework fair??? — Jay Wamsted (@JayWamsted) March 24, 2022

As we delve into this discussion, we explore various facets of why reducing or even eliminating homework could be beneficial. We consider the research, weigh the pros and cons, and examine alternative approaches to traditional homework that can enhance learning without overburdening students.

Insights from Teachers and Education Industry Experts: Diverse Perspectives on Homework

In the ongoing conversation about the role and impact of homework in education, the perspectives of those directly involved in the teaching process are invaluable. Teachers and education industry experts bring a wealth of experience and insights from the front lines of learning. Their viewpoints, shaped by years of interaction with students and a deep understanding of educational methodologies, offer a critical lens through which we can evaluate the effectiveness and necessity of homework in our current educational paradigm.

Check out this video featuring Courtney White, a high school language arts teacher who gained widespread attention for her explanation of why she chooses not to assign homework.

Here are the insights and opinions from various experts in the educational field on this topic:

“I teach 1st grade. I had parents ask for homework. I explained that I don’t give homework. Home time is family time. Time to play, cook, explore and spend time together. I do send books home, but there is no requirement or checklist for reading them. Read them, enjoy them, and return them when your child is ready for more. I explained that as a parent myself, I know they are busy—and what a waste of energy it is to sit and force their kids to do work at home—when they could use that time to form relationships and build a loving home. Something kids need more than a few math problems a week.” — Colleen S. , 1st grade teacher

“The lasting educational value of homework at that age is not proven. A kid says the times tables [at school] because he studied the times tables last night. But over a long period of time, a kid who is drilled on the times tables at school, rather than as homework, will also memorize their times tables. We are worried about young children and their social emotional learning. And that has to do with physical activity, it has to do with playing with peers, it has to do with family time. All of those are very important and can be removed by too much homework.” — David Bloomfield , education professor at Brooklyn College and the City University of New York graduate center

“Homework in primary school has an effect of around zero. In high school it’s larger. (…) Which is why we need to get it right. Not why we need to get rid of it. It’s one of those lower hanging fruit that we should be looking in our primary schools to say, ‘Is it really making a difference?’” — John Hattie , professor

”Many kids are working as many hours as their overscheduled parents and it is taking a toll – psychologically and in many other ways too. We see kids getting up hours before school starts just to get their homework done from the night before… While homework may give kids one more responsibility, it ignores the fact that kids do not need to grow up and become adults at ages 10 or 12. With schools cutting recess time or eliminating playgrounds, kids absorb every single stress there is, only on an even higher level. Their brains and bodies need time to be curious, have fun, be creative and just be a kid.” — Pat Wayman, teacher and CEO of HowtoLearn.com

7 Reasons Why Students Should Not Have Homework

Let’s delve into the reasons against assigning homework to students. Examining these arguments offers important perspectives on the wider educational and developmental consequences of homework practices.

1. Elevated Stress and Health Consequences

The ongoing debate about homework often focuses on its educational value, but a vital aspect that cannot be overlooked is the significant stress and health consequences it brings to students. In the context of American life, where approximately 70% of people report moderate or extreme stress due to various factors like mass shootings, healthcare affordability, discrimination, racism, sexual harassment, climate change, presidential elections, and the need to stay informed, the additional burden of homework further exacerbates this stress, particularly among students.

Key findings and statistics reveal a worrying trend:

• Overwhelming Student Stress: A staggering 72% of students report being often or always stressed over schoolwork, with a concerning 82% experiencing physical symptoms due to this stress.
• Serious Health Issues: Symptoms linked to homework stress include sleep deprivation, headaches, exhaustion, weight loss, and stomach problems.
• Sleep Deprivation: Despite the National Sleep Foundation recommending 8.5 to 9.25 hours of sleep for healthy adolescent development, students average just 6.80 hours of sleep on school nights. About 68% of students stated that schoolwork often or always prevented them from getting enough sleep, which is critical for their physical and mental health.
• Turning to Unhealthy Coping Mechanisms: Alarmingly, the pressure from excessive homework has led some students to turn to alcohol and drugs as a way to cope with stress.

This data paints a concerning picture. Students, already navigating a world filled with various stressors, find themselves further burdened by homework demands. The direct correlation between excessive homework and health issues indicates a need for reevaluation. The goal should be to ensure that homework if assigned, adds value to students’ learning experiences without compromising their health and well-being.

By addressing the issue of homework-related stress and health consequences, we can take a significant step toward creating a more nurturing and effective educational environment. This environment would not only prioritize academic achievement but also the overall well-being and happiness of students, preparing them for a balanced and healthy life both inside and outside the classroom.

2. Inequitable Impact and Socioeconomic Disparities

In the discourse surrounding educational equity, homework emerges as a factor exacerbating socioeconomic disparities, particularly affecting students from lower-income families and those with less supportive home environments. While homework is often justified as a means to raise academic standards and promote equity, its real-world impact tells a different story.

The inequitable burden of homework becomes starkly evident when considering the resources required to complete it, especially in the digital age. Homework today often necessitates a computer and internet access – resources not readily available to all students. This digital divide significantly disadvantages students from lower-income backgrounds, deepening the chasm between them and their more affluent peers.

Key points highlighting the disparities:

• Digital Inequity: Many students lack access to necessary technology for homework, with low-income families disproportionately affected.
• Impact of COVID-19: The pandemic exacerbated these disparities as education shifted online, revealing the extent of the digital divide.
• Educational Outcomes Tied to Income: A critical indicator of college success is linked more to family income levels than to rigorous academic preparation. Research indicates that while 77% of students from high-income families graduate from highly competitive colleges, only 9% from low-income families achieve the same . This disparity suggests that the pressure of heavy homework loads, rather than leveling the playing field, may actually hinder the chances of success for less affluent students.

Moreover, the approach to homework varies significantly across different types of schools. While some rigorous private and preparatory schools in both marginalized and affluent communities assign extreme levels of homework, many progressive schools focusing on holistic learning and self-actualization opt for no homework, yet achieve similar levels of college and career success. This contrast raises questions about the efficacy and necessity of heavy homework loads in achieving educational outcomes.

The issue of homework and its inequitable impact is not just an academic concern; it is a reflection of broader societal inequalities. By continuing practices that disproportionately burden students from less privileged backgrounds, the educational system inadvertently perpetuates the very disparities it seeks to overcome.

3. Negative Impact on Family Dynamics

Homework, a staple of the educational system, is often perceived as a necessary tool for academic reinforcement. However, its impact extends beyond the realm of academics, significantly affecting family dynamics. The negative repercussions of homework on the home environment have become increasingly evident, revealing a troubling pattern that can lead to conflict, mental health issues, and domestic friction.

A study conducted in 2015 involving 1,100 parents sheds light on the strain homework places on family relationships. The findings are telling:

• Increased Likelihood of Conflicts: Families where parents did not have a college degree were 200% more likely to experience fights over homework.
• Misinterpretations and Misunderstandings: Parents often misinterpret their children’s difficulties with homework as a lack of attention in school, leading to feelings of frustration and mistrust on both sides.
• Discriminatory Impact: The research concluded that the current approach to homework disproportionately affects children whose parents have lower educational backgrounds, speak English as a second language, or belong to lower-income groups.

The issue is not confined to specific demographics but is a widespread concern. Samantha Hulsman, a teacher featured in Education Week Teacher , shared her personal experience with the toll that homework can take on family time. She observed that a seemingly simple 30-minute assignment could escalate into a three-hour ordeal, causing stress and strife between parents and children. Hulsman’s insights challenge the traditional mindset about homework, highlighting a shift towards the need for skills such as collaboration and problem-solving over rote memorization of facts.

The need of the hour is to reassess the role and amount of homework assigned to students. It’s imperative to find a balance that facilitates learning and growth without compromising the well-being of the family unit. Such a reassessment would not only aid in reducing domestic conflicts but also contribute to a more supportive and nurturing environment for children’s overall development.

4. Consumption of Free Time

In recent years, a growing chorus of voices has raised concerns about the excessive burden of homework on students, emphasizing how it consumes their free time and impedes their overall well-being. The issue is not just the quantity of homework, but its encroachment on time that could be used for personal growth, relaxation, and family bonding.

Authors Sara Bennett and Nancy Kalish , in their book “The Case Against Homework,” offer an insightful window into the lives of families grappling with the demands of excessive homework. They share stories from numerous interviews conducted in the mid-2000s, highlighting the universal struggle faced by families across different demographics. A poignant account from a parent in Menlo Park, California, describes nightly sessions extending until 11 p.m., filled with stress and frustration, leading to a soured attitude towards school in both the child and the parent. This narrative is not isolated, as about one-third of the families interviewed expressed feeling crushed by the overwhelming workload.

Key points of concern:

• Excessive Time Commitment: Students, on average, spend over 6 hours in school each day, and homework adds significantly to this time, leaving little room for other activities.
• Impact on Extracurricular Activities: Homework infringes upon time for sports, music, art, and other enriching experiences, which are as crucial as academic courses.
• Stifling Creativity and Self-Discovery: The constant pressure of homework limits opportunities for students to explore their interests and learn new skills independently.

The National Education Association (NEA) and the National PTA (NPTA) recommend a “10 minutes of homework per grade level” standard, suggesting a more balanced approach. However, the reality often far exceeds this guideline, particularly for older students. The impact of this overreach is profound, affecting not just academic performance but also students’ attitudes toward school, their self-confidence, social skills, and overall quality of life.

Furthermore, the intense homework routine’s effectiveness is doubtful, as it can overwhelm students and detract from the joy of learning. Effective learning builds on prior knowledge in an engaging way, but excessive homework in a home setting may be irrelevant and uninteresting. The key challenge is balancing homework to enhance learning without overburdening students, allowing time for holistic growth and activities beyond academics. It’s crucial to reassess homework policies to support well-rounded development.

5. Challenges for Students with Learning Disabilities

Homework, a standard educational tool, poses unique challenges for students with learning disabilities, often leading to a frustrating and disheartening experience. These challenges go beyond the typical struggles faced by most students and can significantly impede their educational progress and emotional well-being.

Child psychologist Kenneth Barish’s insights in Psychology Today shed light on the complex relationship between homework and students with learning disabilities:

• Homework as a Painful Endeavor: For students with learning disabilities, completing homework can be likened to “running with a sprained ankle.” It’s a task that, while doable, is fraught with difficulty and discomfort.
• Misconceptions about Laziness: Often, children who struggle with homework are perceived as lazy. However, Barish emphasizes that these students are more likely to be frustrated, discouraged, or anxious rather than unmotivated.
• Limited Improvement in School Performance: The battles over homework rarely translate into significant improvement in school for these children, challenging the conventional notion of homework as universally beneficial.

These points highlight the need for a tailored approach to homework for students with learning disabilities. It’s crucial to recognize that the traditional homework model may not be the most effective or appropriate method for facilitating their learning. Instead, alternative strategies that accommodate their unique needs and learning styles should be considered.

In conclusion, the conventional homework paradigm needs reevaluation, particularly concerning students with learning disabilities. By understanding and addressing their unique challenges, educators can create a more inclusive and supportive educational environment. This approach not only aids in their academic growth but also nurtures their confidence and overall development, ensuring that they receive an equitable and empathetic educational experience.

6. Critique of Underlying Assumptions about Learning

The longstanding belief in the educational sphere that more homework automatically translates to more learning is increasingly being challenged. Critics argue that this assumption is not only flawed but also unsupported by solid evidence, questioning the efficacy of homework as an effective learning tool.

Alfie Kohn , a prominent critic of homework, aptly compares students to vending machines in this context, suggesting that the expectation of inserting an assignment and automatically getting out of learning is misguided. Kohn goes further, labeling homework as the “greatest single extinguisher of children’s curiosity.” This critique highlights a fundamental issue: the potential of homework to stifle the natural inquisitiveness and love for learning in children.

The lack of concrete evidence supporting the effectiveness of homework is evident in various studies:

• Marginal Effectiveness of Homework: A study involving 28,051 high school seniors found that the effectiveness of homework was marginal, and in some cases, it was counterproductive, leading to more academic problems than solutions.
• No Correlation with Academic Achievement: Research in “ National Differences, Global Similarities ” showed no correlation between homework and academic achievement in elementary students, and any positive correlation in middle or high school diminished with increasing homework loads.
• Increased Academic Pressure: The Teachers College Record published findings that homework adds to academic pressure and societal stress, exacerbating performance gaps between students from different socioeconomic backgrounds.

These findings bring to light several critical points:

• Quality Over Quantity: According to a recent article in Monitor on Psychology , experts concur that the quality of homework assignments, along with the quality of instruction, student motivation, and inherent ability, is more crucial for academic success than the quantity of homework.
• Counterproductive Nature of Excessive Homework: Excessive homework can lead to more academic challenges, particularly for students already facing pressures from other aspects of their lives.
• Societal Stress and Performance Gaps: Homework can intensify societal stress and widen the academic performance divide.

The emerging consensus from these studies suggests that the traditional approach to homework needs rethinking. Rather than focusing on the quantity of assignments, educators should consider the quality and relevance of homework, ensuring it truly contributes to learning and development. This reassessment is crucial for fostering an educational environment that nurtures curiosity and a love for learning, rather than extinguishing it.

7. Issues with Homework Enforcement, Reliability, and Temptation to Cheat

In the academic realm, the enforcement of homework is a subject of ongoing debate, primarily due to its implications on student integrity and the true value of assignments. The challenges associated with homework enforcement often lead to unintended yet significant issues, such as cheating, copying, and a general undermining of educational values.

Key points highlighting enforcement challenges:

• Difficulty in Enforcing Completion: Ensuring that students complete their homework can be a complex task, and not completing homework does not always correlate with poor grades.
• Reliability of Homework Practice: The reliability of homework as a practice tool is undermined when students, either out of desperation or lack of understanding, choose shortcuts over genuine learning. This approach can lead to the opposite of the intended effect, especially when assignments are not well-aligned with the students’ learning levels or interests.
• Temptation to Cheat: The issue of cheating is particularly troubling. According to a report by The Chronicle of Higher Education , under the pressure of at-home assignments, many students turn to copying others’ work, plagiarizing, or using creative technological “hacks.” This tendency not only questions the integrity of the learning process but also reflects the extreme stress that homework can induce.
• Parental Involvement in Completion: As noted in The American Journal of Family Therapy , this raises concerns about the authenticity of the work submitted. When parents complete assignments for their children, it not only deprives the students of the opportunity to learn but also distorts the purpose of homework as a learning aid.

In conclusion, the challenges of homework enforcement present a complex problem that requires careful consideration. The focus should shift towards creating meaningful, manageable, and quality-driven assignments that encourage genuine learning and integrity, rather than overwhelming students and prompting counterproductive behaviors.

Addressing Opposing Views on Homework Practices

While opinions on homework policies are diverse, understanding different viewpoints is crucial. In the following sections, we will examine common arguments supporting homework assignments, along with counterarguments that offer alternative perspectives on this educational practice.

1. Improvement of Academic Performance

Homework is commonly perceived as a means to enhance academic performance, with the belief that it directly contributes to better grades and test scores. This view posits that through homework, students reinforce what they learn in class, leading to improved understanding and retention, which ultimately translates into higher academic achievement.

However, the question of why students should not have homework becomes pertinent when considering the complex relationship between homework and academic performance. Studies have indicated that excessive homework doesn’t necessarily equate to higher grades or test scores. Instead, too much homework can backfire, leading to stress and fatigue that adversely affect a student’s performance. Reuters highlights an intriguing correlation suggesting that physical activity may be more conducive to academic success than additional homework, underscoring the importance of a holistic approach to education that prioritizes both physical and mental well-being for enhanced academic outcomes.

2. Reinforcement of Learning

Homework is traditionally viewed as a tool to reinforce classroom learning, enabling students to practice and retain material. However, research suggests its effectiveness is ambiguous. In instances where homework is well-aligned with students’ abilities and classroom teachings, it can indeed be beneficial. Particularly for younger students , excessive homework can cause burnout and a loss of interest in learning, counteracting its intended purpose.

Furthermore, when homework surpasses a student’s capability, it may induce frustration and confusion rather than aid in learning. This challenges the notion that more homework invariably leads to better understanding and retention of educational content.

3. Development of Time Management Skills

Homework is often considered a crucial tool in helping students develop important life skills such as time management and organization. The idea is that by regularly completing assignments, students learn to allocate their time efficiently and organize their tasks effectively, skills that are invaluable in both academic and personal life.

However, the impact of homework on developing these skills is not always positive. For younger students, especially, an overwhelming amount of homework can be more of a hindrance than a help. Instead of fostering time management and organizational skills, an excessive workload often leads to stress and anxiety . These negative effects can impede the learning process and make it difficult for students to manage their time and tasks effectively, contradicting the original purpose of homework.

4. Preparation for Future Academic Challenges

Homework is often touted as a preparatory tool for future academic challenges that students will encounter in higher education and their professional lives. The argument is that by tackling homework, students build a foundation of knowledge and skills necessary for success in more advanced studies and in the workforce, fostering a sense of readiness and confidence.

Contrarily, an excessive homework load, especially from a young age, can have the opposite effect . It can instill a negative attitude towards education, dampening students’ enthusiasm and willingness to embrace future academic challenges. Overburdening students with homework risks disengagement and loss of interest, thereby defeating the purpose of preparing them for future challenges. Striking a balance in the amount and complexity of homework is crucial to maintaining student engagement and fostering a positive attitude towards ongoing learning.

5. Parental Involvement in Education

Homework often acts as a vital link connecting parents to their child’s educational journey, offering insights into the school’s curriculum and their child’s learning process. This involvement is key in fostering a supportive home environment and encouraging a collaborative relationship between parents and the school. When parents understand and engage with what their children are learning, it can significantly enhance the educational experience for the child.

However, the line between involvement and over-involvement is thin. When parents excessively intervene by completing their child’s homework,  it can have adverse effects . Such actions not only diminish the educational value of homework but also rob children of the opportunity to develop problem-solving skills and independence. This over-involvement, coupled with disparities in parental ability to assist due to variations in time, knowledge, or resources, may lead to unequal educational outcomes, underlining the importance of a balanced approach to parental participation in homework.

Exploring Alternatives to Homework and Finding a Middle Ground

In the ongoing debate about the role of homework in education, it’s essential to consider viable alternatives and strategies to minimize its burden. While completely eliminating homework may not be feasible for all educators, there are several effective methods to reduce its impact and offer more engaging, student-friendly approaches to learning.

Alternatives to Traditional Homework

• Project-Based Learning: This method focuses on hands-on, long-term projects where students explore real-world problems. It encourages creativity, critical thinking, and collaborative skills, offering a more engaging and practical learning experience than traditional homework. For creative ideas on school projects, especially related to the solar system, be sure to explore our dedicated article on solar system projects .
• Flipped Classrooms: Here, students are introduced to new content through videos or reading materials at home and then use class time for interactive activities. This approach allows for more personalized and active learning during school hours.
• Reading for Pleasure: Encouraging students to read books of their choice can foster a love for reading and improve literacy skills without the pressure of traditional homework assignments. This approach is exemplified by Marion County, Florida , where public schools implemented a no-homework policy for elementary students. Instead, they are encouraged to read nightly for 20 minutes . Superintendent Heidi Maier’s decision was influenced by research showing that while homework offers minimal benefit to young students, regular reading significantly boosts their learning. For book recommendations tailored to middle school students, take a look at our specially curated article .

Ideas for Minimizing Homework

• Limiting Homework Quantity: Adhering to guidelines like the “ 10-minute rule ” (10 minutes of homework per grade level per night) can help ensure that homework does not become overwhelming.
• Quality Over Quantity: Focus on assigning meaningful homework that is directly relevant to what is being taught in class, ensuring it adds value to students’ learning.
• Homework Menus: Offering students a choice of assignments can cater to diverse learning styles and interests, making homework more engaging and personalized.
• Integrating Technology: Utilizing educational apps and online platforms can make homework more interactive and enjoyable, while also providing immediate feedback to students. To gain deeper insights into the role of technology in learning environments, explore our articles discussing the benefits of incorporating technology in classrooms and a comprehensive list of educational VR apps . These resources will provide you with valuable information on how technology can enhance the educational experience.

For teachers who are not ready to fully eliminate homework, these strategies offer a compromise, ensuring that homework supports rather than hinders student learning. By focusing on quality, relevance, and student engagement, educators can transform homework from a chore into a meaningful component of education that genuinely contributes to students’ academic growth and personal development. In this way, we can move towards a more balanced and student-centric approach to learning, both in and out of the classroom.

Homework Policy Still Going Strong

• Posted January 15, 2014
• By Lory Hough

It's become one of those stories that has legs. Two years after we ran a feature story on whether schools should assign homework, we're still receiving letters to the editor and new tweets. On the Ed. site, the story has consistently been one of the most shared.

" Are You Down With or Done With Homework ?" featured Stephanie Brant, principal of Gaithersburg Elementary School in Gaithersburg, Md., who got rid of nightly homework in exchange for nightly reading and longer projects. At the time, Brant was just a few months into the homework change. Since the story in Ed. continues to spark so much interest among readers, we asked Brant if the policy was still in place, how it was going, and whether she had been approached by other media.

"Absolutely," she says, noting that The Washington Post , Family magazine, msn living, and The Huffington Post contacted her, as did several principals and school boards, asking if they could visit the school.

And the policy continues. "What's changed is the culture and community that we created," she says. "We've really built a culture of reading, at school and at home." Of course, some parents, especially new parents, still ask questions. "They ask, 'My child isn't doing math homework?' And I get it. I'm a parent, too."

But now, instead of reassuring them with talk of what she hopes will happen, she can tell them what has happened — students are making progress.

"The majority of our kids don't go to preschool. Now, since the policy, the majority of them leave kindergarten reading," she says. "At the end of the last school year, we looked at every student who started reading below grade level. Every one of them has risen at least 1.2 levels in growth. We've also had kids who grew 10 and 11 grade levels in one year."

Brant has made it easy for kids to embrace the new reading culture. Not only does she give them the time at home to read by not assigning other homework, but she also makes books readily available: Around school, there are book baskets in the halls. During the summer, in her gray Acura RDX, she becomes a one-woman bookmobile, driving around the city twice a week, giving out free books to kids — some donated, many that she paid for herself.

It's exactly what Brant wanted when she changed the homework policy. "Reading here has become the norm," she says. "My hope when I started this was to make reading a habit. Students who read become adults who read."

Open Alert: Harvard Yard Closed to the Public

Harvard is hard, but there’s support to help.

During my first few weeks as a Harvard student, I came upon a realization – my preconceptions were true. Harvard is hard.

This phrase became my new saying – with challenging multivariable calculus concepts, research papers and midterms coming up, my parents were asking how I was doing. Well, Harvard is hard , I would say with a smile. The reason I could say this with a smile was largely because I knew I was not alone – not only were there many relatable first-year students in my classes, but Harvard has countless resources to support its students.

The academic transition from high school to college causes many incoming first-years to feel nervous, and I was no exception. As the summer came to a close and the beginning of college approached, I began thinking more and more about Harvard and how best to manage the workload associated with my new courses. Should I change the way I take notes? How do I navigate my academic schedule with an increased amount of free time in college? Where do I turn if I don’t understand a concept? Am I cut out for Harvard?

While Harvard is indeed challenging, when the time came to actually start classes, I was pleasantly surprised at the faculty's, teaching staff's and advisors' collaborative, supportive and down-to-earth nature. Looking back on my first semester, I owe a lot of my success to the vast amount of academic resources Harvard offers - even remotely. In fact, the sheer number of these can feel a little overwhelming if you try to take advantage of all of them. Because of this, I hope to share a few of the academic resources I have found most helpful during my first semester at Harvard:

Academic Resource Center (ARC)

Life coaching - but for academics! The Academic Resource Center supports students by giving tips on a range of topics from note-taking to time management and test anxiety. I was first introduced to the ARC through their First-Year Fridays series over the summer before I officially started Harvard. These presentations were led by academic coaches at Harvard designed to introduce the incoming first-years to academic life at Harvard. It was through these summer workshops that I decided to meet with an ARC coach before the start of classes. A conversation with a coach that was meant to discuss my note-taking style ended up including broader advice on course recommendations and essay writing. The ARC offers a wide range of academic support, and I have become a regular in their accountability group, one-on-one coaching, and other workshops.

Peer Tutoring

Peer tutoring offers the opportunity for undergraduate students to be tutored by other undergraduate students who have taken the same course in the past, and, even though peer tutoring is through the ARC, I thought it should have its own section. In today’s world, I feel like tutoring, and asking for help in general, can sometimes get a bad rap. I have no shame in asking for help, and tutoring is not just for students who are struggling academically. While I definitely have signed up for tutoring to help cover a concept which confused me, I also use tutoring as a general opportunity to study, reviewing practice tests and talking over concepts with students who have taken the class before. Peer tutoring at Harvard has never been intimidating for me, and it is very easy to sign up for a tutoring session. 

Office Hours

As I said earlier, I have no shame in asking for help, and I actually include office hours in my weekly academic schedule along with my classes. Office hours are designated times throughout the week that professors and teaching fellows (graduate students who aid in teaching a course) set aside for undergraduates to visit. If I am unable to attend the office hours of my professors or teaching fellow in Life Sciences 1B, an integrated course on genetics, genomics, and evolution that I am currently taking, there are over 40 hours worth of office hours offered by other teaching fellows that I can go to with questions. Office hours are not only a way to ask course and content questions, though; they are also a great chance to get to know a professor and their research interests, receive career advice, and discuss research opportunities.

P-set Groups

I feel like a huge misconception about Harvard is that it is a super competitive place where everyone works by themselves and never asks for help or collaborates with peers. My first semester could not have been more different from that. In many scenarios, Harvard actually encourages students to collaborate. P-set (“problem set," Harvard’s lingo for homework in STEM classes) groups are a great example. At the start of each semester, it is not out of the ordinary to get a message from a friend or see a message in a group chat asking if any fellow students would like to form a p-set group for a particular course. Not only are p-set groups a source of accountability - they also help me to feel confident about my learning by bouncing ideas off of classmates.

I hope these reflections helped to shed light on some academic resources available at Harvard. As you walk away from reading this, please remember one thing – while Harvard is a challenging place, there is incredible support to help!

Does Homework Really Help Students Learn?

A conversation with a Wheelock researcher, a BU student, and a fourth-grade teacher

“Quality homework is engaging and relevant to kids’ lives,” says Wheelock’s Janine Bempechat. “It gives them autonomy and engages them in the community and with their families. In some subjects, like math, worksheets can be very helpful. It has to do with the value of practicing over and over.” Photo by iStock/Glenn Cook Photography

Do your homework.

If only it were that simple.

Educators have debated the merits of homework since the late 19th century. In recent years, amid concerns of some parents and teachers that children are being stressed out by too much homework, things have only gotten more fraught.

“Homework is complicated,” says developmental psychologist Janine Bempechat, a Wheelock College of Education & Human Development clinical professor. The author of the essay “ The Case for (Quality) Homework—Why It Improves Learning and How Parents Can Help ” in the winter 2019 issue of Education Next , Bempechat has studied how the debate about homework is influencing teacher preparation, parent and student beliefs about learning, and school policies.

She worries especially about socioeconomically disadvantaged students from low-performing schools who, according to research by Bempechat and others, get little or no homework.

BU Today  sat down with Bempechat and Erin Bruce (Wheelock’17,’18), a new fourth-grade teacher at a suburban Boston school, and future teacher freshman Emma Ardizzone (Wheelock) to talk about what quality homework looks like, how it can help children learn, and how schools can equip teachers to design it, evaluate it, and facilitate parents’ role in it.

BU Today: Parents and educators who are against homework in elementary school say there is no research definitively linking it to academic performance for kids in the early grades. You’ve said that they’re missing the point.

Bempechat : I think teachers assign homework in elementary school as a way to help kids develop skills they’ll need when they’re older—to begin to instill a sense of responsibility and to learn planning and organizational skills. That’s what I think is the greatest value of homework—in cultivating beliefs about learning and skills associated with academic success. If we greatly reduce or eliminate homework in elementary school, we deprive kids and parents of opportunities to instill these important learning habits and skills.

We do know that beginning in late middle school, and continuing through high school, there is a strong and positive correlation between homework completion and academic success.

That’s what I think is the greatest value of homework—in cultivating beliefs about learning and skills associated with academic success.

You talk about the importance of quality homework. What is that?

Quality homework is engaging and relevant to kids’ lives. It gives them autonomy and engages them in the community and with their families. In some subjects, like math, worksheets can be very helpful. It has to do with the value of practicing over and over.

What are your concerns about homework and low-income children?

The argument that some people make—that homework “punishes the poor” because lower-income parents may not be as well-equipped as affluent parents to help their children with homework—is very troubling to me. There are no parents who don’t care about their children’s learning. Parents don’t actually have to help with homework completion in order for kids to do well. They can help in other ways—by helping children organize a study space, providing snacks, being there as a support, helping children work in groups with siblings or friends.

Isn’t the discussion about getting rid of homework happening mostly in affluent communities?

Yes, and the stories we hear of kids being stressed out from too much homework—four or five hours of homework a night—are real. That’s problematic for physical and mental health and overall well-being. But the research shows that higher-income students get a lot more homework than lower-income kids.

Teachers may not have as high expectations for lower-income children. Schools should bear responsibility for providing supports for kids to be able to get their homework done—after-school clubs, community support, peer group support. It does kids a disservice when our expectations are lower for them.

The conversation around homework is to some extent a social class and social justice issue. If we eliminate homework for all children because affluent children have too much, we’re really doing a disservice to low-income children. They need the challenge, and every student can rise to the challenge with enough supports in place.

What did you learn by studying how education schools are preparing future teachers to handle homework?

My colleague, Margarita Jimenez-Silva, at the University of California, Davis, School of Education, and I interviewed faculty members at education schools, as well as supervising teachers, to find out how students are being prepared. And it seemed that they weren’t. There didn’t seem to be any readings on the research, or conversations on what high-quality homework is and how to design it.

Erin, what kind of training did you get in handling homework?

Bruce : I had phenomenal professors at Wheelock, but homework just didn’t come up. I did lots of student teaching. I’ve been in classrooms where the teachers didn’t assign any homework, and I’ve been in rooms where they assigned hours of homework a night. But I never even considered homework as something that was my decision. I just thought it was something I’d pull out of a book and it’d be done.

I started giving homework on the first night of school this year. My first assignment was to go home and draw a picture of the room where you do your homework. I want to know if it’s at a table and if there are chairs around it and if mom’s cooking dinner while you’re doing homework.

The second night I asked them to talk to a grown-up about how are you going to be able to get your homework done during the week. The kids really enjoyed it. There’s a running joke that I’m teaching life skills.

Friday nights, I read all my kids’ responses to me on their homework from the week and it’s wonderful. They pour their hearts out. It’s like we’re having a conversation on my couch Friday night.

It matters to know that the teacher cares about you and that what you think matters to the teacher. Homework is a vehicle to connect home and school…for parents to know teachers are welcoming to them and their families.

Bempechat : I can’t imagine that most new teachers would have the intuition Erin had in designing homework the way she did.

Ardizzone : Conversations with kids about homework, feeling you’re being listened to—that’s such a big part of wanting to do homework….I grew up in Westchester County. It was a pretty demanding school district. My junior year English teacher—I loved her—she would give us feedback, have meetings with all of us. She’d say, “If you have any questions, if you have anything you want to talk about, you can talk to me, here are my office hours.” It felt like she actually cared.

Bempechat : It matters to know that the teacher cares about you and that what you think matters to the teacher. Homework is a vehicle to connect home and school…for parents to know teachers are welcoming to them and their families.

Ardizzone : But can’t it lead to parents being overbearing and too involved in their children’s lives as students?

Bempechat : There’s good help and there’s bad help. The bad help is what you’re describing—when parents hover inappropriately, when they micromanage, when they see their children confused and struggling and tell them what to do.

Good help is when parents recognize there’s a struggle going on and instead ask informative questions: “Where do you think you went wrong?” They give hints, or pointers, rather than saying, “You missed this,” or “You didn’t read that.”

Bruce : I hope something comes of this. I hope BU or Wheelock can think of some way to make this a more pressing issue. As a first-year teacher, it was not something I even thought about on the first day of school—until a kid raised his hand and said, “Do we have homework?” It would have been wonderful if I’d had a plan from day one.

Insightful! The values about homework in elementary schools are well aligned with my intuition as a parent.

when i finish my work i do my homework and i sometimes forget what to do because i did not get enough sleep

same omg it does not help me it is stressful and if I have it in more than one class I hate it.

Same I think my parent wants to help me but, she doesn’t care if I get bad grades so I just try my best and my grades are great.

I think that last question about Good help from parents is not know to all parents, we do as our parents did or how we best think it can be done, so maybe coaching parents or giving them resources on how to help with homework would be very beneficial for the parent on how to help and for the teacher to have consistency and improve homework results, and of course for the child. I do see how homework helps reaffirm the knowledge obtained in the classroom, I also have the ability to see progress and it is a time I share with my kids

The answer to the headline question is a no-brainer – a more pressing problem is why there is a difference in how students from different cultures succeed. Perfect example is the student population at BU – why is there a majority population of Asian students and only about 3% black students at BU? In fact at some universities there are law suits by Asians to stop discrimination and quotas against admitting Asian students because the real truth is that as a group they are demonstrating better qualifications for admittance, while at the same time there are quotas and reduced requirements for black students to boost their portion of the student population because as a group they do more poorly in meeting admissions standards – and it is not about the Benjamins. The real problem is that in our PC society no one has the gazuntas to explore this issue as it may reveal that all people are not created equal after all. Or is it just environmental cultural differences??????

I get you have a concern about the issue but that is not even what the point of this article is about. If you have an issue please take this to the site we have and only post your opinion about the actual topic

This is not at all what the article is talking about.

This literally has nothing to do with the article brought up. You should really take your opinions somewhere else before you speak about something that doesn’t make sense.

we have the same name

so they have the same name what of it?

lol you tell her

totally agree

What does that have to do with homework, that is not what the article talks about AT ALL.

Yes, I think homework plays an important role in the development of student life. Through homework, students have to face challenges on a daily basis and they try to solve them quickly.I am an intense online tutor at 24x7homeworkhelp and I give homework to my students at that level in which they handle it easily.

More than two-thirds of students said they used alcohol and drugs, primarily marijuana, to cope with stress.

You know what’s funny? I got this assignment to write an argument for homework about homework and this article was really helpful and understandable, and I also agree with this article’s point of view.

I also got the same task as you! I was looking for some good resources and I found this! I really found this article useful and easy to understand, just like you! ^^

i think that homework is the best thing that a child can have on the school because it help them with their thinking and memory.

I am a child myself and i think homework is a terrific pass time because i can’t play video games during the week. It also helps me set goals.

Homework is not harmful ,but it will if there is too much

I feel like, from a minors point of view that we shouldn’t get homework. Not only is the homework stressful, but it takes us away from relaxing and being social. For example, me and my friends was supposed to hang at the mall last week but we had to postpone it since we all had some sort of work to do. Our minds shouldn’t be focused on finishing an assignment that in realty, doesn’t matter. I completely understand that we should have homework. I have to write a paper on the unimportance of homework so thanks.

homework isn’t that bad

Are you a student? if not then i don’t really think you know how much and how severe todays homework really is

i am a student and i do not enjoy homework because i practice my sport 4 out of the five days we have school for 4 hours and that’s not even counting the commute time or the fact i still have to shower and eat dinner when i get home. its draining!

i totally agree with you. these people are such boomers

why just why

they do make a really good point, i think that there should be a limit though. hours and hours of homework can be really stressful, and the extra work isn’t making a difference to our learning, but i do believe homework should be optional and extra credit. that would make it for students to not have the leaning stress of a assignment and if you have a low grade you you can catch up.

Studies show that homework improves student achievement in terms of improved grades, test results, and the likelihood to attend college. Research published in the High School Journal indicates that students who spent between 31 and 90 minutes each day on homework “scored about 40 points higher on the SAT-Mathematics subtest than their peers, who reported spending no time on homework each day, on average.” On both standardized tests and grades, students in classes that were assigned homework outperformed 69% of students who didn’t have homework. A majority of studies on homework’s impact – 64% in one meta-study and 72% in another – showed that take home assignments were effective at improving academic achievement. Research by the Institute for the Study of Labor (IZA) concluded that increased homework led to better GPAs and higher probability of college attendance for high school boys. In fact, boys who attended college did more than three hours of additional homework per week in high school.

So how are your measuring student achievement? That’s the real question. The argument that doing homework is simply a tool for teaching responsibility isn’t enough for me. We can teach responsibility in a number of ways. Also the poor argument that parents don’t need to help with homework, and that students can do it on their own, is wishful thinking at best. It completely ignores neurodiverse students. Students in poverty aren’t magically going to find a space to do homework, a friend’s or siblings to help them do it, and snacks to eat. I feel like the author of this piece has never set foot in a classroom of students.

THIS. This article is pathetic coming from a university. So intellectually dishonest, refusing to address the havoc of capitalism and poverty plays on academic success in life. How can they in one sentence use poor kids in an argument and never once address that poor children have access to damn near 0 of the resources affluent kids have? Draw me a picture and let’s talk about feelings lmao what a joke is that gonna put food in their belly so they can have the calories to burn in order to use their brain to study? What about quiet their 7 other siblings that they share a single bedroom with for hours? Is it gonna force the single mom to magically be at home and at work at the same time to cook food while you study and be there to throw an encouraging word?

Also the “parents don’t need to be a parent and be able to guide their kid at all academically they just need to exist in the next room” is wild. Its one thing if a parent straight up is not equipped but to say kids can just figured it out is…. wow coming from an educator What’s next the teacher doesn’t need to teach cause the kid can just follow the packet and figure it out?

Well then get a tutor right? Oh wait you are poor only affluent kids can afford a tutor for their hours of homework a day were they on average have none of the worries a poor child does. Does this address that poor children are more likely to also suffer abuse and mental illness? Like mentioned what about kids that can’t learn or comprehend the forced standardized way? Just let em fail? These children regularly are not in “special education”(some of those are a joke in their own and full of neglect and abuse) programs cause most aren’t even acknowledged as having disabilities or disorders.

But yes all and all those pesky poor kids just aren’t being worked hard enough lol pretty sure poor children’s existence just in childhood is more work, stress, and responsibility alone than an affluent child’s entire life cycle. Love they never once talked about the quality of education in the classroom being so bad between the poor and affluent it can qualify as segregation, just basically blamed poor people for being lazy, good job capitalism for failing us once again!

why the hell?

you should feel bad for saying this, this article can be helpful for people who has to write a essay about it

This is more of a political rant than it is about homework

I know a teacher who has told his students their homework is to find something they are interested in, pursue it and then come share what they learn. The student responses are quite compelling. One girl taught herself German so she could talk to her grandfather. One boy did a research project on Nelson Mandela because the teacher had mentioned him in class. Another boy, a both on the autism spectrum, fixed his family’s computer. The list goes on. This is fourth grade. I think students are highly motivated to learn, when we step aside and encourage them.

The whole point of homework is to give the students a chance to use the material that they have been presented with in class. If they never have the opportunity to use that information, and discover that it is actually useful, it will be in one ear and out the other. As a science teacher, it is critical that the students are challenged to use the material they have been presented with, which gives them the opportunity to actually think about it rather than regurgitate “facts”. Well designed homework forces the student to think conceptually, as opposed to regurgitation, which is never a pretty sight

Wonderful discussion. and yes, homework helps in learning and building skills in students.

not true it just causes kids to stress

Homework can be both beneficial and unuseful, if you will. There are students who are gifted in all subjects in school and ones with disabilities. Why should the students who are gifted get the lucky break, whereas the people who have disabilities suffer? The people who were born with this “gift” go through school with ease whereas people with disabilities struggle with the work given to them. I speak from experience because I am one of those students: the ones with disabilities. Homework doesn’t benefit “us”, it only tears us down and put us in an abyss of confusion and stress and hopelessness because we can’t learn as fast as others. Or we can’t handle the amount of work given whereas the gifted students go through it with ease. It just brings us down and makes us feel lost; because no mater what, it feels like we are destined to fail. It feels like we weren’t “cut out” for success.

homework does help

here is the thing though, if a child is shoved in the face with a whole ton of homework that isn’t really even considered homework it is assignments, it’s not helpful. the teacher should make homework more of a fun learning experience rather than something that is dreaded

This article was wonderful, I am going to ask my teachers about extra, or at all giving homework.

I agree. Especially when you have homework before an exam. Which is distasteful as you’ll need that time to study. It doesn’t make any sense, nor does us doing homework really matters as It’s just facts thrown at us.

Homework is too severe and is just too much for students, schools need to decrease the amount of homework. When teachers assign homework they forget that the students have other classes that give them the same amount of homework each day. Students need to work on social skills and life skills.

I disagree.

Beyond achievement, proponents of homework argue that it can have many other beneficial effects. They claim it can help students develop good study habits so they are ready to grow as their cognitive capacities mature. It can help students recognize that learning can occur at home as well as at school. Homework can foster independent learning and responsible character traits. And it can give parents an opportunity to see what’s going on at school and let them express positive attitudes toward achievement.

Homework is helpful because homework helps us by teaching us how to learn a specific topic.

As a student myself, I can say that I have almost never gotten the full 9 hours of recommended sleep time, because of homework. (Now I’m writing an essay on it in the middle of the night D=)

I am a 10 year old kid doing a report about “Is homework good or bad” for homework before i was going to do homework is bad but the sources from this site changed my mind!

Homeowkr is god for stusenrs

I agree with hunter because homework can be so stressful especially with this whole covid thing no one has time for homework and every one just wants to get back to there normal lives it is especially stressful when you go on a 2 week vaca 3 weeks into the new school year and and then less then a week after you come back from the vaca you are out for over a month because of covid and you have no way to get the assignment done and turned in

As great as homework is said to be in the is article, I feel like the viewpoint of the students was left out. Every where I go on the internet researching about this topic it almost always has interviews from teachers, professors, and the like. However isn’t that a little biased? Of course teachers are going to be for homework, they’re not the ones that have to stay up past midnight completing the homework from not just one class, but all of them. I just feel like this site is one-sided and you should include what the students of today think of spending four hours every night completing 6-8 classes worth of work.

Are we talking about homework or practice? Those are two very different things and can result in different outcomes.

Homework is a graded assignment. I do not know of research showing the benefits of graded assignments going home.

Practice; however, can be extremely beneficial, especially if there is some sort of feedback (not a grade but feedback). That feedback can come from the teacher, another student or even an automated grading program.

As a former band director, I assigned daily practice. I never once thought it would be appropriate for me to require the students to turn in a recording of their practice for me to grade. Instead, I had in-class assignments/assessments that were graded and directly related to the practice assigned.

I would really like to read articles on “homework” that truly distinguish between the two.

oof i feel bad good luck!

thank you guys for the artical because I have to finish an assingment. yes i did cite it but just thanks

thx for the article guys.

Homework is good

I think homework is helpful AND harmful. Sometimes u can’t get sleep bc of homework but it helps u practice for school too so idk.

I agree with this Article. And does anyone know when this was published. I would like to know.

It was published FEb 19, 2019.

Studies have shown that homework improved student achievement in terms of improved grades, test results, and the likelihood to attend college.

i think homework can help kids but at the same time not help kids

This article is so out of touch with majority of homes it would be laughable if it wasn’t so incredibly sad.

There is no value to homework all it does is add stress to already stressed homes. Parents or adults magically having the time or energy to shepherd kids through homework is dome sort of 1950’s fantasy.

What lala land do these teachers live in?

Homework gives noting to the kid

Homework is Bad

homework is bad.

why do kids even have homework?

The Realities of Remote Work

• Laura Amico

Work-life boundaries are blurring and managers worry about productivity. What can be done?

The Covid-19 pandemic sparked what economist Nicholas Bloom calls the “ working-from-home economy .” While some workers may have had flexibility to work remotely before the pandemic, this unprecedented shift to remote work looks like it could be here to stay in some form.

The Ladder of Inference: Building Self-Awareness to Be A Better Human-Centered Leader

• Human-centered leadership requires self-awareness, which can be difficult to teach.
• The Ladder of Inference provides a model for raising leaders’ self-awareness and has several additional practical applications.
• The Ladder of Inference supports leadership fitness by developing balance and flexibility.

“Contrary to popular belief, studies have shown that people do not always learn from experience, that expertise does not help people root out false information, and that seeing ourselves as highly experienced can keep us from doing our homework, seeking disconfirming evidence, and questioning our assumptions.” [i]

Boost Self-awareness with the Ladder of Inference

A recent study by Harvard Business Publishing Corporate Learning focused on the importance of human-centered leadership (HCL), [ii] but getting leaders to change behaviors or even see the need to change can be a challenge. Additionally, HCL is a complex topic with many facets, which begs the question: Where do I start? Helping leaders develop self-awareness might be a good place to consider.

Think of a time you were in the presence of a leader who lacked self-awareness—it shouldn’t be hard. Research indicates that only about 15% of people are sufficiently self-aware [i] and that there is less than a 30% correlation between people’s actual and self-perceived competence. [iii] That same research shows that a leader’s lack of self-awareness negatively impacts decision making, collaboration, and conflict management.

Self-awareness, a fundamental component of emotional intelligence, is a cornerstone of HCL, as it enables leaders to cultivate a deeper understanding of themselves and their impact on others. Leaders with strong self-awareness are attuned to their emotions, strengths, and areas for development, allowing them to make conscious decisions and navigate complex situations with clarity and integrity.

So, self-awareness is important, but how do you help leaders build it? A good first step is teaching them to use the Ladder of Inference, a model introduced by Harvard Professor Emeritus Chris Argyris. [iv]

The Ladder of Inference

The Ladder of Inference illustrates how people unconsciously climb a mental ladder of assumptions and beliefs based on their observations and experiences.

This process occurs rapidly and often subconsciously, leading individuals to filter information, make interpretations, and take action—all of which can be influenced by biases and past experiences. It represents what Daniel Kahneman, in Thinking, Fast and Slow , would call a System 1 process. [v]

• System 1 is the fast, automatic processing that requires little energy.
• System 2 is the rational, conscious, effortful processing.

Kahneman explains how System 1 makes educated guesses to come to quick conclusions but shows no record of how it came to its conclusion. “System 1 does not keep track of alternatives that it rejects, or even the fact that there were alternatives.” The problem is that the guess it makes may be wrong (the conclusion as well) but you will believe it unless System 2 steps in to evaluate it. This often does not happen because System 2 is “lazy” or is often distracted. By using the ladder, we can employ System 2 to guide our conclusions and provide a framework to analyze them, with more faulty conclusions being identified and corrected.

Select data from available information

Imagine a ladder leaning against a wall, sitting in a puddle. The puddle in which the ladder sits is data or facts. The amount of data in any given situation is more than our brains can handle, so filters are applied. Two people looking at the same data will filter and retain different data, but no one will process all the data completely or in the same way. As you step on the first rung of the ladder, your brain selects and triages data, keeping some and ignoring others.

Add meanings to selected data

Up one step on the ladder, our brains push the data through the filters and lenses of our paradigms. These are biases, worldviews, and mindsets. Think of glasses with yellow lenses. When you first put them on, things look yellow; then your brain adjusts and everything looks normal until you take off the glasses, and then everything looks green. What you were looking at never changed, but how you perceived it did.

Interpret the data and make assumptions

On the next rung up the ladder, you interpret the data and begin to assign meaning to it. You make assumptions and fill in gaps. Have you ever been reading an email and realized that you were hearing the writer’s voice and tone in your head? The tone of voice you hear is likely your interpretation being added, and our interpretations are powerfully affected by context, experiences, and culture. This is also the step where you may start to assign valence to the situation: good or bad, threat or reward, benevolent or evil.

Draw conclusions from assumptions

As you get close to the top of the ladder, you draw a conclusion or an inference. From where you stand, your conclusion is clear, obvious, and important. Your inference feels like a fact, and you cannot imagine any other sane person coming to a different one. Because of this certainty, when we share our brilliant insight with others, we feel no need to explain how we arrived at it because the validity of our conclusion is so obvious to us but, sadly, not necessarily to anyone else. [vi]

Adopt beliefs based on assumptions

Adding complexity to the situation is the profound influence of our mental models—our ingrained values, assumptions, and beliefs about the functioning of the world—on the way each of us ascends our respective ladder of inference. To depict this concept visually, one could also liken these mental models to the sides of the ladder, providing structure and coherence to our reasoning process. For example, people who embrace the “think positively” mindset often infer that the world is largely benevolent. On the other hand, those who hold an “expect the worst” mentality are inclined to filter and judge occurrences in a way that reflects their negative outlook. [vi] Carol Dweck’s work points out how profound an impact mindset (fixed or growth) can have on behavior and outcomes. [vii]

This is how different people standing in the same puddle of data can wind up with their ladders against different walls, reaching vastly different conclusions.

Applying the Ladder of Inference to raise self-awareness

Self-awareness should increase the moment a person learns about the ladder. The fact that an opaque and mostly unconscious process is being brought to the consciousness is the first step (pun intended) in raising self-awareness. It is like breathing; if you pay no attention, it happens automatically. However, when you notice your breathing, you can control it. It moves from Kahneman’s System 1 to System 2, [v] from automatic to intentional.

The second step is to slow the process down and examine how we climbed the ladder—an act of self-reflection. What data did we choose? What data did we reject? What assumptions did we make? What biases may have influenced the process? Reflecting on the thought process and examining the assumptions we make can lead to a deeper understanding of ourselves and our interaction with others. This is the beginning of self-awareness.

The Ladder of Inference is easy enough to teach and practice. Most people can recall a time when they jumped to a conclusion that later turned out to be wrong. Have them climb back down the ladder of that conclusion to analyze their reasoning. Also, have them reflect on the consequences of faulty conclusions.

Consistent awareness and evaluation of our ladders should lead to the insight that many of our conclusions that feel like facts are only strongly held opinions, although some learners may need help getting here. It can be uncomfortable to realize that many things you thought were solid facts are actually flimsy opinions, so your ego will put up some resistance.

Why is getting leaders to this realization important? Because, as pointed out earlier, most leaders overestimate their competency, so getting them to be less certain of their conclusions is beneficial. Certainty is the enemy of curiosity. Knowing is a barrier to learning. Why would I learn what I already know? Research shows that two outcomes of rising up the corporate levels of leadership are loss of empathy and an increase in hubris. [viii] The antidote is self-awareness and curiosity; the ladder supports both.

How the Ladder of Inference supports leadership fitness

In Harvard Business Publishing Corporate Learning’s study on HCL and a more recent paper, we propose that leadership fitness, like physical fitness, requires strength, balance, flexibility, and endurance. [ii] The ladder most directly supports the middle two.

We suggest that part of balance is the “ability to read situations more accurately by challenging subconscious encoding processes that lead us to ignore some cues in favor of others” that is, disrupting unconscious bias and default behavior patterns through metacognition, or thinking about your thinking. After consciously disrupting these thought processes, leaders display greater balance by intentionally choosing leadership behaviors. The ladder is a tool that helps leaders make implicit thought patterns explicit, allowing for analysis, choice, and correction in leadership style.

The ladder supports flexibility by interrupting habits. Does a person have the choice to act differently without noticing their default thinking? Maybe, but the chance seems slim. Imagine that you are driving home from work, tired and hungry. The traffic is really bad, and someone cuts you off. For most people, the response is automatic; the only option is what word is chosen to describe the other driver: jerk, idiot, moron.

However, those are conclusions. If that default process is interrupted and assumptions are evaluated using the ladder, you may realize that the person who cut you off may not be evil or lacking in intelligence and that there are many possible alternate conclusions. You might also realize that you yourself have accidentally cut people off before, and you are not evil or stupid, right? Now that you have access to different possibilities of how to react, you can choose to send positive thoughts toward that person, hoping they get where they are going safely. Before the ladder, you only had options; after the ladder, you have new possibilities of how to act. That is flexibility.

The bottom line

The Ladder of Inference is a simple but powerful tool for self-awareness that can be used in many situations to increase leadership balance and flexibility, supporting human-centered leadership. But this is not the limit of the application of the ladder in leadership. In the next post in this series, we will look at how the ladder can be used to support better decision making, manage productive conflict, and create space for building trust and collaboration.

How Bad Are Ultraprocessed Foods, Really?

They’re clearly linked to poor health. But scientists are only beginning to understand why.

Credit... Casey Zhang for The New York Times

Supported by

By Alice Callahan

• Published May 6, 2024 Updated May 10, 2024

In the mid-1990s, Carlos Monteiro, a nutritional epidemiologist in Brazil, noticed something alarming: Obesity rates among children in his country were rising rapidly.

To understand why, he and his colleagues at the University of São Paulo scrutinized data on the food buying patterns of Brazilian households to see if they had changed in recent years. The researchers found that people were purchasing less sugar, salt, cooking oils and staples like rice and beans, and more processed foods like sodas, sausages, instant noodles, packaged breads and cookies.

To describe that second category of food, Dr. Monteiro said, the team introduced a new term into the scientific literature — ultraprocessed foods, or UPFs — and defined it. They would later link UPFs to weight gain in children and adults in Brazil.

Since then, scientists have found associations between UPFs and a range of health conditions , including heart disease, Type 2 diabetes, obesity, gastrointestinal diseases and depression, as well as earlier death.

That’s concerning, experts say , since ultraprocessed foods have become a major part of people’s diets worldwide. They account for 67 percent of the calories consumed by children and teenagers in the United States, for example.

But many questions remain. What are ultraprocessed foods, exactly? And how strong is the evidence that they’re harmful? We asked experts to answer these and other questions.

What are ultraprocessed foods?

In order to study foods based on how they were processed, Dr. Monteiro and his colleagues developed a food classification system called Nova, named after the Portuguese and Latin words for “new.” It has since been adopted by researchers across the world.

The Nova system sorts foods into four categories :

Unprocessed or minimally processed foods , like fresh or frozen fruits and vegetables, beans, lentils, meat, poultry, fish, eggs, milk, plain yogurt, rice, pasta, corn meal, flour, coffee, tea and herbs and spices.

Processed culinary ingredients , such as cooking oils, butter, sugar, honey, vinegar and salt.

Processed foods made by combining foods from Category 1 with the ingredients of Category 2 and preserving or modifying them with relatively simple methods like canning, bottling, fermentation and baking. This group includes freshly baked bread, most cheeses and canned vegetables, beans and fish. These foods may contain preservatives that extend shelf life.

Ultraprocessed foods made using industrial methods and ingredients you wouldn’t typically find in grocery stores — like high-fructose corn syrup, hydrogenated oils and concentrated proteins like soy isolate. They often contain additives like flavorings, colorings or emulsifiers to make them appear more attractive and palatable. Think sodas and energy drinks, chips, candies, flavored yogurts, margarine, chicken nuggets, hot dogs, sausages, lunch meats, boxed macaroni and cheese, infant formulas and most packaged breads, plant milks, meat substitutes and breakfast cereals.

“If you look at the ingredient list and you see things that you wouldn’t use in home cooking, then that’s probably an ultraprocessed food,” said Brenda Davy, a nutrition professor at Virginia Tech.

The Nova system notably doesn’t classify foods based on nutrients like fat, fiber, vitamins or minerals. It’s “agnostic to nutrition,” said Maya Vadiveloo, an associate professor of nutrition at the University of Rhode Island.

That has led to debate among nutrition experts about whether it’s useful for describing the healthfulness of a food, partly since many UPFs — like whole grain breads, flavored yogurts and infant formulas — can provide valuable nutrients, Dr. Vadiveloo said.

Are ultraprocessed foods harmful?

Most research linking UPFs to poor health is based on observational studies, in which researchers ask people about their diets and then track their health over many years. In a large review of studies that was published in 2024, scientists reported that consuming UPFs was associated with 32 health problems, with the most convincing evidence for heart disease-related deaths, Type 2 diabetes and common mental health issues like anxiety and depression.

Such studies are valuable, because they can look at large groups of people — the 2024 review included results from nearly 10 million — over the many years it can take for chronic health conditions to develop, said Josiemer Mattei, an associate professor of nutrition at the Harvard T.H. Chan School of Public Health. She added that the consistency of the link between UPFs and health issues increased her confidence that there was a real problem with the foods.

But the observational studies also have limitations, said Lauren O’Connor, a nutrition scientist and epidemiologist who formerly worked at the Department of Agriculture and the National Institutes of Health. It’s true that there is a correlation between these foods and chronic diseases, she said, but that doesn’t mean that UPFs directly cause poor health.

Dr. O’Connor questioned whether it’s helpful to group such “starkly different” foods — like Twinkies and breakfast cereals — into one category. Certain types of ultraprocessed foods, like sodas and processed meats , are more clearly harmful than others. UPFs like flavored yogurts and whole grain breads , on the other hand, have been associated with a reduced risk of developing Type 2 diabetes.

Clinical trials are needed to test if UPFs directly cause health problems, Dr. O’Connor said. Only one such study, which was small and had some limitations, has been done, she said.

In that study , published in 2019, 20 adults with a range of body sizes lived in a research hospital at the National Institutes of Health for four weeks. For two weeks, they ate mainly unprocessed or minimally processed foods, and for another two weeks, they ate mainly UPFs. The diets had similar amounts of calories and nutrients, and the participants could eat as much as they wanted at each meal.

During their two weeks on the ultraprocessed diet, participants gained an average of two pounds and consumed about 500 calories more per day than they did on the unprocessed diet. During their time on the unprocessed diet, they lost about two pounds.

That finding might help explain the link between UPFs, obesity and other metabolic conditions, said Kevin Hall, a nutrition and metabolism researcher at the National Institutes of Health, who led the trial. But the study needs to be replicated, which Dr. Hall is in the process of doing now.

Why might UPFs be harmful?

There are many “strong opinions” about why ultraprocessed foods are unhealthy, Dr. Hall said. “But there’s actually not a lot of rigorous science” on what those mechanisms are, he added.

Because UPFs are often cheap, convenient and accessible, they’re probably displacing healthier foods from our diets, Dr. Hall said.

But he and other scientists think that the foods could be having more direct effects on health. They can be easy to overeat — maybe because they contain hard-to-resist combinations of carbohydrates, sugars, fats and salt , are high-calorie and easy to chew. It’s also possible that resulting blood sugar spikes may damage arteries or ramp up inflammation , or that certain food additives or chemicals may interfere with hormones, cause a “ leaky” intestine or disrupt the gut microbiome.

Researchers, including Dr. Hall and Dr. Davy, are beginning to conduct small clinical trials that will test some of these theories. Such studies may help identify the most harmful UPFs and even suggest how they may be made healthier, Dr. Hall said.

But most researchers think there are various ways the foods are causing harm. “Rarely in nutrition is there a single factor that fully explains the relationship between foods and some health outcome,” Dr. Vadiveloo said.

What should we do about ultraprocessed foods?

In 2014, Dr. Monteiro helped write new dietary guidelines for Brazil that advised people to avoid ultraprocessed foods.

Other countries like Mexico , Israel and Canada have also explicitly recommended avoiding or limiting UPFs or “highly processed foods.” The U.S. dietary guidelines contain no such advice, but an advisory committee is currently looking into the evidence on how UPFs may affect weight gain, which could influence the 2025 guidelines.

It’s difficult to know what to do about UPFs in the United States, where so much food is already ultraprocessed and people with lower incomes can be especially dependent on them, Dr. Hall said.

“At the end of the day, they are an important source of food, and food is food,” Dr. Mattei added. “We really cannot vilify them,” she said.

While research continues, expert opinions differ on how people should approach UPFs. Dr. Monteiro said that the safest course is to avoid them altogether — to swap flavored yogurt for plain yogurt with fruit, for example, or to buy a fresh loaf from a local bakery instead of packaged bread, if you can afford to do so.

Dr. Vadiveloo suggested a more moderate strategy, focusing on limiting UPFs that don’t provide valuable nutrients, like soda and cookies. She also recommended eating more fruits, vegetables, whole grains (ultraprocessed or not), legumes, nuts and seeds.

Cook at home as much as you can, using minimally processed foods, Dr. Davy said. “We can’t really say a whole lot beyond that at this point.”
