This issue focus discusses the conclusions of a recent MDRC working paper, Project-Based Learning: A Literature Review. The paper found that project-based learning holds promise for improving students’ outcomes but that much remains to be learned about its effectiveness and about how its implementation can be strengthened.
In some experimental evaluations of classroom- or school-level interventions, random assignment is conducted at the student level and the program is delivered at the higher level. This paper clarifies the correct causal interpretation of “program impacts” when this study design is used and discusses the implications and limitations of this research design. A real example is used to demonstrate the paper’s key points.
