This type of study is designed to see how participants (learners, teachers, parents) change and develop as a result of some type of intervention. The intervention could be a single event like a training session or a series of events like set of lessons given over several weeks. To determine how participants change and develop, data are obtained both before and after the intervention, usually with an identical survey/test. Unless designed with a control and experimental group with random assignment, the results must be interpreted with caution and the study should include a limitations section.
This study requires IRB approval.
