A solid understanding of fractions is the cornerstone for acquiring proficiency with rational numbers and paves the way for learning advanced mathematical concepts, such as algebra. Fraction difficulties limit not only students' educational and vocational opportunities but also their ability to solve everyday problems. Students who exit 6th grade…

Background/Context: Early childhood education research has consistently found evidence of immediate, positive effects on developmental outcomes. Despite these strong initial benefits, follow-up analyses often reveal that these effects fadeout in the years following participation (e.g., Bailey et al., 2017, Clements et al., 2013; Lipsey et al.…

This secondary analysis of data from a randomized control trial of an early mathematics intervention, ROOTS, explored whether patterns of intervention response were best categorized by the typical response/non-response binary or a more complex framework with additional response profiles. Participants included kindergarten students at risk for…

A growing body of research documents the effectiveness of classroom management programs on a range of student outcomes, yet few early-career teachers receive training on these practices prior to entering the classroom. Moreover, few studies have attended to how variations in teacher distress or level of classroom misbehavior affects training…

This report presents findings from exploratory, descriptive meta-analyses of effect sizes reported by the first 82 EEF evaluations that used a randomised controlled trial (RCT) or clustered RCT impact evaluation design published up to January 2019. The review used a theoretical framework derived from literature with five overarching themes to…

This document summarises key findings from the quantitative strands of a review of the Education Endowment Foundation (EEF) evaluations that had reported from the establishment of EEF in 2011 up to January 2019. The quantitative strands summarised include meta-analyses of effect sizes reported for attainment outcomes and descriptive analyses of…

This document provides supplementary statistical tables to support the review of Education Endowment Foundation (EEF) evaluations. This includes: (1) Descriptive (univariate) tables for all explanatory variables; (2) Tables for the meta-analyses of primary ITT effect sizes; (3) Tables for the meta-analyses of secondary ITT effect sizes; (4) Tables…

Increasingly, prekindergarten programs with literacy outcome goals are seeking to implement evidence-based practices to improve results. Such efforts require instructional intervention strategies to engage children as well as strategies to support teacher implementation. Reported is the iterative development of Literacy 3D, an enhanced support…

Few evidence-based practices, defined as the use of empirically supported research and clinical expertise for children with autism, have been successfully implemented and sustained in schools. This study examined the perspectives of school personnel (n = 39) on implementing a social engagement intervention for children with autism. Semi-structured…

Background: Most studies of teacher professional development (PD) do not rigorously test impact on teaching practice and student learning. This makes it difficult to define what is truly "effective." The "Science Teachers Learning from Lesson Analysis" (STeLLA) PD program, in contrast, was studied in a cluster randomized…

Disparities in academic science performance remain for diverse learners, including students with learning disabilities and English learners. Educational technology offers the potential to support diverse learners by taking into account their specific needs and unique strengths. This paper reports on third-year results of a 3-year randomized…

Research has shown that teacher effectiveness is the most important school-based factor that influences student outcomes, including student achievement. Studies have also shown that there is substantial variation in teacher effectiveness, such that some teachers improve student outcomes at a much faster rate than others. The strong influence of…

Many schools are beginning to implement universal behavior management interventions as part of multitiered systems of support. Past research suggests that teachers need support to implement new practices with fidelity. Coaching is one method for supporting implementation, but little is understood about how coaching takes place when relying on…

Research Learning Communities (RLC) was an intervention that aimed to improve teaching quality and learning outcomes by raising teachers' awareness, understanding, and use of educational research in their teaching practice. Two Evidence Champion teachers from each school attended four RLC workshops with peers from up to four other schools.…

Childhood emotional and behavioral problems are prevalent in elementary classroom settings, making it imperative that high-quality, efficacious training be available to support teachers in managing disruptive and distressed child behaviors. Our study used a randomized control design to examine the impact of 36 hours of preservice education…
