This study examined the impact of a commonly adopted elementary universal social-emotional learning program, Second Step, on student social-emotional and academic outcomes following 2 years of implementation. The cluster-randomized wait-list control trial included 61 schools, 321 teachers, and 8,941 early elementary students across 2 states, with…

The purpose of this replication study was to examine the impact of the Teacher Study Group (TSG) professional development in vocabulary on first-grade teachers' knowledge of vocabulary instruction and observed teaching practice, and on students' vocabulary knowledge. Sixty-two schools from 16 districts in four states were randomly assigned to…

This pilot study evaluated a novel professional development (PD) model designed to prepare K-12 educators in high-need, rural school districts to teach evidence-based argument writing. The PD showed teachers how to engage students in discussions about visual art using Visual Thinking Strategies to enhance students' argumentation writing. Twenty…

This pilot study evaluated a novel professional development (PD) model designed to prepare K-12 educators in high-need rural school districts to teach evidence-based argument writing. The PD model showed teachers how to engage students in discussions about visual art using Visual Thinking Strategies (VTS) to enhance students' argumentation…

This article presents the results of an evaluation of Positive Family Support, an ecological family intervention and treatment approach to parent supports and family management training developed from a history of basic and translational research. This effectiveness trial, with 41 public middle schools randomly assigned to intervention or control,…

This study explores the effects of a Spanish vocabulary intervention on the literacy outcomes of students at risk for vocabulary difficulties in Chile. We screened 2nd-grade students (N = 84) with a standardized Spanish vocabulary measure. We then randomly assigned students who scored below the 40th percentile (n = 30) to an intervention or…

This study examines measurement of creative ideational behaviors alongside factors of student engagement that may play a role in the development of students' creative potential during early adolescence in school. Two studies used exploratory and confirmatory factor analyses, cross-validation, and invariance testing of 2 extant measures with…

Background: Little is known about factors that influence home-based child care providers' participation in professional development. Factors that predict participation in activities that are designed to promote the utilization and maintenance of skills taught are of particular interest. Objective: Our aim was to examine factors in the home-based…

Well-designed mathematics instruction focused on concepts and problem-solving skills associated with measurement and data analysis can build a foundational understanding for more advanced mathematics. This study investigated the efficacy of the Precision Mathematics Level 1 (PM-L1) intervention, a Tier 2 print- and technology-based mathematics…

This article presents findings of an efficacy trial examining the effect of a multitiered instruction and intervention model on first grade at-risk students' reading outcomes. Schools (N = 16) were randomly assigned to the treatment or control condition. In the fall of Grade 1, students were assigned to an instructional tier on the basis of…

Oregon's Effective Behavioral and Instructional Support Systems (EBISS) initiative was implemented in 25 school districts. The initiative trained and coached district leaders and teachers in the use of the EBISS model through the lens of implementation science. The EBISS model integrates school-wide positive behavior intervention and supports…

Contemporary state math standards emphasize that students must demonstrate an understanding of the mathematical ideas underlying the computations that have typically been the core of the elementary school math curriculum. The standards have put an increased emphasis on the study of fractions in upper elementary grades, which are the years during…

Classroom management remains a challenge for many teachers. The approach and delivery of professional development (PD) in classroom management may determine how well teachers are able to apply evidence-based approaches in their classrooms. We use existing literature to identify the key features that make in-service PD effective and present them as…

We report on a practitioner implementation of Fusion, a first-grade mathematics intervention. Studies such as this evaluation of a loose implementation under realistic conditions are important to curriculum developers' understanding of how evidence-based programs and tools work under a variety of implementation scenarios. In this…
