There is a growing belief that access to academic opportunities during the summer can help close the achievement gap between low-income students and their higher-income peers. But while significant research is emerging on summer programs for school-age children, information on the preschool period is limited. The Expanding Children's Early…

Purpose: Adolescent females continue to face health consequences associated with risky sexual behaviors such as unintended pregnancies and sexually transmitted diseases. The purpose of this study was to investigate the efficacy of a gender-specific intervention targeted to early adolescent females. Method: This study used an intent to treat…

This article describes a study which compares the effectiveness of the flipped classroom relative to the traditional lecture-based classroom. We investigated two implementations of the flipped classroom. The first implementation did not actively encourage cooperative learning, with students progressing through the course at their own pace. With…

This paper examines the "ecological validity" of a randomized controlled trial (RCT) conducted in 42 high schools to measure the impact of a content literacy program. This study of comparable schools implementing the same program in different contexts highlights characteristics that are often not attended to in rigorous effectiveness…

This multiyear scale-up effectiveness study of Open Court Reading (OCR) involved approximately 4,500 students and more than 1,000 teachers per year in Grades K-5 from 49 elementary schools in seven districts across the country. Using a school-level cluster randomized trial design, we assessed the implementation and effectiveness of Open Court…

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…

Based on the experience of evaluating 2 cross-age peer-tutoring interventions, we argue that researchers need to pay greater attention to causal mechanisms within the context of school-based randomised controlled trials. Without studying mechanisms, researchers are less able to explain the underlying causal processes that give rise to results from…

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…

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…

Fidelity of implementation is a commonly used term that is not well understood yet frequently assessed in schools today. This paper will discuss the different approaches commonly used in schools (e.g., structural, procedural, etc.) and then present them in relation to student outcomes within a seven-month intervention study with at-risk…

This mixed-method study examined the implementation and the challenges to implementation for participants in randomized controlled trials of two school-based programs for early adolescents: the Tier One Word Generation (WG) program, and the Tier Two Strategic Adolescent Reading Intervention (STARI). Levels of implementation for WG and STARI varied…

To succeed in today's economy, students need both proficiency in the "three Rs" (reading, writing and arithmetic) and strong applied skills. Communication skills, team work, and critical thinking have long been at the top of employers' lists of applied skills they seek in employees. States are responding to employers' needs by putting in…

Lesson Study is a popular approach to teacher professional development used widely in Japan. It involves a small group of teachers co-planning a series of lessons based on a shared learning goal for the pupils, with one teacher leading the co-constructed lesson and their colleagues invited to observe pupil learning in the lesson. The team then…

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…
