Pre-experimental designs.
Pre-experiments are the simplest form of research design. In a pre-experiment either a single group or multiple groups are observed subsequent to some agent or treatment presumed to cause change.
Types of Pre-Experimental Design
One-shot case study design, one-group pretest-posttest design, static-group comparison.
A single group is studied at a single point in time after some treatment that is presumed to have caused change. The carefully studied single instance is compared to general expectations of what the case would have looked like had the treatment not occurred and to other events casually observed. No control or comparison group is employed.
A single case is observed at two time points, one before the treatment and one after the treatment. Changes in the outcome of interest are presumed to be the result of the intervention or treatment. No control or comparison group is employed.
A group that has experienced some treatment is compared with one that has not. Observed differences between the two groups are assumed to be a result of the treatment.
Validity of Results
An important drawback of pre-experimental designs is that they are subject to numerous threats to their validity . Consequently, it is often difficult or impossible to dismiss rival hypotheses or explanations. Therefore, researchers must exercise extreme caution in interpreting and generalizing the results from pre-experimental studies.
One reason that it is often difficult to assess the validity of studies that employ a pre-experimental design is that they often do not include any control or comparison group. Without something to compare it to, it is difficult to assess the significance of an observed change in the case. The change could be the result of historical changes unrelated to the treatment, the maturation of the subject, or an artifact of the testing.
Even when pre-experimental designs identify a comparison group, it is still difficult to dismiss rival hypotheses for the observed change. This is because there is no formal way to determine whether the two groups would have been the same if it had not been for the treatment. If the treatment group and the comparison group differ after the treatment, this might be a reflection of differences in the initial recruitment to the groups or differential mortality in the experiment.
Advantages and Disadvantages
As exploratory approaches, pre-experiments can be a cost-effective way to discern whether a potential explanation is worthy of further investigation.
Disadvantages
Pre-experiments offer few advantages since it is often difficult or impossible to rule out alternative explanations. The nearly insurmountable threats to their validity are clearly the most important disadvantage of pre-experimental research designs.

Tabel 3.1 One-Shot Case Study Treatment Observasi X O Sumber : Sugiono, 2017. Keterangan : X : Pemberian perlakuan (treatment) O : Observasi setelah treatment (dapat berupa post-test) Tujuan penelitian untuk mengetauhi keefektifannya proses blended learning dan capaian hasil belajar siswa dengan menngunakan desain one-shot case study.
Quasy eksperimen merupakan desain perlakuan tunggal ( one shot case study ) merupakan desain yang paling sederhana. Terhadap sekolompok subjek diberi perlakuan (X), kemudian dilakukan pengamatan (Y). Dalam desain ini sekelompok subjek penelitian memperoleh perlakuan, selanjutnya diukur variabel yang hendak diamati (Latipun, 2004:114).

The One-Shot Case Study. The one-shot case study design is shown in figure 4.1e. It is also called the ex post facto design because a single group of people is measured on some dependent variable after an intervention has taken place. This is the most common research design in culture change studies, where it is obviously impossible to ...
One-shot case study merupakan metode penelitian yang efisien dan fleksibel untuk mempelajari suatu fenomena atau kejadian secara mendalam dalam waktu yang singkat. Metode ini dapat menghasilkan data kualitatif yang kaya dan mendalam, namun juga memiliki batasan seperti kurangnya kontrol variabel dan tidak adanya kelompok pembanding.
