We report the results of a preregistered, cluster randomized controlled trial of a mathematics learning intervention known as interleaved practice. Whereas most mathematics assignments consist of a block of problems devoted to the same skill or concept, an interleaved assignment is arranged so that no 2 consecutive problems require the same…

Two experimental studies to improve vocabulary knowledge and comprehension were conducted in 7th-grade social studies classes with English language learners (ELLs). Two different nonoverlapping samples of classes of 7th-grade students (N = 381 and N = 507) were randomly assigned at the classroom (i.e., section) level to a social studies…

Successful implementation of evidence-based educational practices at scale is of great importance but has presented significant challenges. In this article, the authors address the following questions: How does the level of on-site technical assistance affect student outcomes? Do teachers' fidelity of treatment implementation and their perceptions…

Although functional assessment-based interventions have produced desired outcomes in student behavior in applied settings, most of those interventions involved strong, sustained participation with researchers in intervention design, implementation, and assessment. In this article, we describe a systematic approach to designing, implementing, and…
