Relevance interventions have shown a great potential to foster motivation and achievement (Lazowski & Hulleman, 2016). Yet, further research is warranted to test how such interventions can be successfully implemented in practice. We conducted a cluster-randomized trial in ninth-grade math classrooms to test the effectiveness of a relevance…

Beginning in 2002, researchers developed, implemented, and evaluated the efficacy of an English reading intervention for first-grade English learners using multiple randomized control trials (RCTs). As a result of this efficacy work, researchers successfully competed for an IES Goal 4 effectiveness study using the same intervention. Unlike the…

An appropriate estimate of statistical power is critical for the design of intervention studies. Although the inclusion of a pretest covariate in the test of the primary outcome can increase statistical power, samples selected on the basis of pretest performance may demonstrate range restriction on the selection measure and other correlated…

The purpose of this closely aligned conceptual replication study was to investigate the efficacy of a Tier 2 kindergarten mathematics intervention. The replication study differed from the initial randomized controlled trial on three important elements: geographical region, timing of the intervention, and instructional context of the…

For children with the most serious and persistent academic and behavior problems, parent involvement in education, particularly teacher perceptions of involvement, is essential to avert their expected long-term negative outcomes. Despite the widespread interest in and perceived importance of parent involvement in education, however, few…

Combining data from a series of three planned consecutive randomized controlled trials, the present study investigates two literacy interventions for preschool children with autism spectrum disorder. For the first cohort, children were randomized to interactive book reading (IBR; treatment) or business as usual (BAU; control); in Cohort 2,…

This study employs a sequential multiple assignment randomized trial (SMART) design to develop an adaptive intervention with personalized print and digital content for kindergarten to Grade 2 children (n = 273). In Stage 1, we ask whether it is better for children to receive an adaptive intervention based on (a) 10 conceptually coherent texts or…

The present study examined the effectiveness of the oral history approach with respect to students' historical competence. A total of 35 ninth-grade classes (N = 900) in Germany were randomly assigned to one of four conditions--live, video, text, or a (nontreated) control group--in a pretest, posttest, and follow-up design. Comparing the three…

A wide and rich body of literature has identified the family as the key context influencing children's development. In response, school districts and policymakers have sought to engage parents in children's learning, particularly low-income families. Meta-analyses conclude that efforts to engage low-income parents do improve students' academic…

This study evaluated two 20-week reading interventions for pupils entering secondary school with reading difficulties. The interventions were delivered by trained teaching assistants (three 35-min sessions per week). 287 pupils (ages 11-13) from 27 schools were randomly allocated to three groups: reading intervention (targeting word recognition…

Brief, targeted self-affirmation writing exercises have recently been offered as a way to reduce racial achievement gaps, but evidence about their effects in educational settings is mixed, leaving ambiguity about the likely benefits of these strategies if implemented broadly. A key limitation in interpreting these mixed results is that they come…

Research Findings: This study investigated how mean classroom-level shyness scores moderated the impacts of "INSIGHTS" into "Children's Temperament" on instructional support and students' math and reading skills in kindergarten and 1st-grade classrooms. "INSIGHTS" is a temperament-based social-emotional learning…

The purpose of this set of analyses, conducted on a randomized control trial examining the effects of a fourth-grade fraction intervention, was to assess the initial academic deficit severity hypothesis. With this hypothesis, at-risk students with more severe initial academic deficits are expected to profit less from intervention than do students…
