Re-Conceptualizing SMART Designs as a Hybrid of Randomized and Regression Discontinuity Designs: Opportunities, Cautions
Peer reviewed Peer reviewed
Direct linkDirect link
William Herbert Yeaton – International Journal of Research & Method in Education, 2024
Though previously unacknowledged, a SMART (Sequential Multiple Assignment Randomized Trial) design uses both regression discontinuity (RD) and randomized controlled trial (RCT) designs. This combination structure creates a conceptual symbiosis between the two designs that enables both RCT- and previously unrecognized, RD-based inferential claims.…

Examining Heterogeneity of Education Intervention Effects Using Quantile Mixed Models: A Re-Analysis of a Cluster-Randomized Controlled Trial of a Fluency-Based Mathematics Intervention
Peer reviewed Peer reviewed
Direct linkDirect link
Paul Thompson; Kaydee Owen; Richard P. Hastings – International Journal of Research & Method in Education, 2024
Traditionally, cluster randomized controlled trials are analyzed with the average intervention effect of interest. However, in populations that contain higher degrees of heterogeneity or variation may differ across different values of a covariate, which may not be optimal. Within education and social science contexts, exploring the variation in…
