Supplemental information
The goal of this project is to create a framework that provides applied researchers with a set of practical tools and clearly lays out all the relevant assumptions for assessing treatment effect variation. When testing the impact of an intervention or treatment, education researchers are increasingly asking questions such as: (1) To what extent does the effect vary across units? (2) What accounts for this variation? These questions are closely related to understanding how treatments work, and, in particular, which aspects of a treatment's implementation are most strongly connected to its efficacy.
This project has three major goals. First, the team will develop the framework and accompanying theory in order to build accessible tools for applied researchers. Second, the researchers will use Monte Carlo simulation studies to investigate the performance of these tools under a wide range of practical settings. Third, the project team will apply these tools to real datasets in order to gauge their usefulness to applied researchers in terms of both interfacing with the software and making use of the analytical results. To disseminate the results, the researchers will prepare peer-reviewed conference presentations and journal manuscripts, and deliver a workshop and a short course for practitioners. Researchers will also make the user-friendly software available online.
