Evidence · 2 claims (2 for) · 1 study (1 review),q2· 0 of 1 report an effect size · 2 claims rest on one study
Description¶
The report organizes the quantitative methods literature into three research topics: subgroup (moderator) analyses using participants' characteristics "measured before the intervention is implemented"; subgroup analyses based on "participants' experiences, mediators, and outcomes measured after program implementation"; and impact estimation when treatment effects vary. This taxonomy structures the report's technical guidance for education impact evaluations.
Accounts¶
- Three-part taxonomy of methods for studying variation in treatment effects: pre-intervention subgroup analyses, post-intervention subgroup analyses, and impact estimation under varying effects: The report organizes the quantitative methods literature into three research topics: subgroup (moderator) analyses using participants' characteristics "measured before the intervention is implemented"; subgroup analyses based on "participants' experiences, mediators, and outcomes measured after program implementation"; and impact estimation when treatment effects vary. This taxonomy structures the report's technical guidance for education impact evaluations. (Peter Z. Schochet et al. (2014))
Claims¶
- Quantitative methods exist for assessing how impacts of educational interventions on instructional practices and student learning differ across students, educators, and schools [+W]
- Methods for estimating impacts when treatment effects vary apply to randomized controlled trials and are also applicable to quasi-experimental designs [+W]
