This paper presents two studies of an intervention designed to help undergraduates comprehend mathematical proofs. The intervention used multimedia resources that presented proofs with audio commentary and visual animations designed to focus attention on logical relationships. In study 1, students studied an e-Proof or a standard written proof and…

Purpose: Evidence suggests that extensive experience with lexical tones or musical training provides an advantage in perceiving nonnative lexical tones. This investigation concerns whether such an advantage is evident in learning nonnative lexical tones based on the distributional structure of the input. Method: Using an established protocol,…

Maternal education is one of the strongest predictors of children's academic outcomes. One possible explanation for this is that more highly educated mothers more frequently engage in parenting practices that may promote children's later cognitive development; however, most of this evidence is correlational. This study uses Head Start Impact Study…

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…

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.…

The Accelerated Study in Associate Programs (ASAP), developed by the City University of New York (CUNY), is an uncommonly comprehensive and long-term program designed to address low graduation rates among community college students. MDRC has been studying the effects of ASAP on low-income students with developmental (remedial) education needs at…

Using a low inference observation instrument, we investigated the effect of an ongoing, intensive, and structured virtual professional development [VPD] on fidelity of implementation across conditions in a randomized control trial validation study implemented in seven Texas school districts. The observations were collected three time in the…

The objective of this study was to look across strategies used in a wide range of studies to build a framework for researchers to use in conceptualizing the recruitment process. This paper harvests lessons learned across 19 randomized controlled trials in K-12 school settings conducted by a leading research organization to identify strategies that…

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…

Based on a one-year longitudinal experimental study with 3,782 kindergarten school children across 15 countries, this article examines the association between prayer and happiness. Results show that the post-test scores on the faces scale were higher for the participant group who had taken the prayer lessons vis-à-vis the comparison group.…

Although graduation rates are rising, the high school dropout problem remains a national crisis, and evidence-based information about interventions for at-risk students is critically needed. Prior research shows that Check & Connect, an individualized mentoring program, has positive effects on school persistence and progression for students…

Peer tutoring is a structured process of co-operative learning, supported by social interdependence theory shown to have cognitive and affective level benefits. During a RCT, this study explores teacher perceptions (n=62) of effects of co-operative learning, including implementation issues, using a mixed methods approach during a 16-week peer…

In this longitudinal study, the cross-language transfer from second language (L2) to first language (L1) was examined among Spanish-speaking English-language learners in an English intervention (Grades 1-3) in the southwest United States. Path analysis revealed statistically significant transfers (ps < 0.05) for the treatment group from English…

Despite schools increasingly adopting multitiered systems of support (MTSS) for prevention and intervention of mental health concerns, many are slow to adopt universal mental health screening (UMHS), a core MTSS feature, due to concerns about their limited capacity to meet the needs of all identified. In this study, we examined differences in the…
