This study examines the efficacy, cost, and implementation of an integrated science and literacy curriculum for kindergarten. The study was conducted in a large urban district and included 1,589 students in 71 classrooms in 21 schools. The research includes a multi-site cluster-randomized controlled trial and mixed-methods cost and implementation…

Principals are the second-largest school-based contributor to K-12 students' academic progress. However, there is little research evaluating whether efforts to develop principals' skills improve school effectiveness. We conducted randomized controlled trial studies of the impacts of a professional development program called the Executive…

With national focus on reading and math achievement, science and social studies have received less instructional time. Yet, accumulating evidence suggests that content knowledge is an important predictor of proficient reading. Starting with a design study, we developed content-area literacy instruction (CALI) as an individualized (or personalized)…

We report the results of a preregistered, cluster randomized controlled trial of a mathematics learning intervention known as interleaved practice. Whereas most mathematics assignments consist of a block of problems devoted to the same skill or concept, an interleaved assignment is arranged so that no 2 consecutive problems require the same…

Analyses of literacy and numeracy levels worldwide by the Organisation for Economic Cooperation and Development suggest that the U.S. population has one of the lowest numeracy levels among developed nations. Sixty-four percent of American adults are unable to use math and interpret math problems that most higher-level jobs require, and a full 30…

This report presents the findings from an external evaluation of Project COMPASS, an effort by Wake Technical Community College to redesign community college online courses to improve outcomes, particularly for students of color. The evaluation used a randomized controlled trial in which students were randomly assigned to course sections taught by…

Problem/Purpose: Young children with developmental speech and/or language impairment (DSLI) often fail to develop important oral language and early literacy skills that are foundational for subsequent schooling and reading success. The purpose of this investigation was to examine the efficacy of the TELL curriculum and associated evidence-based…

The purpose of this study was to assess the impact of the Arts for Learning (A4L) Lessons Project on the literacy and life skills of students in grades 3, 4, and 5.

This article examines the effectiveness of a technology-based algebra curriculum in a wide variety of middle schools and high schools in seven states. Participating schools were matched into similar pairs and randomly assigned to either continue with the current algebra curriculum for 2 years or to adopt Cognitive Tutor Algebra I (CTAI), which…

The Carnegie Learning Cognitive Tutor curricula are based on cognitive models, which include a representation of the learner's thinking, strategies, and misconceptions. The Cognitive Tutor curricula typically speed up learning and yield greater learning as compared to traditional math curricula (Morgan & Ritter, 2002; Sarkis, 2004; Koedinger,…

The inclusion of social and emotional learning (SEL) curricula in preschools may help prevent emotional and behavioral problems. This study evaluated the effects of a SEL curriculum, "Strong Start Pre-K," on the social and emotional competence of 52 preschool students using a quasi-experimental, non-equivalent control group design.…

This study aimed to determine the efficacy of a content acquisition and reading comprehension treatment implemented by eighth-grade social studies teachers. Using a within-teacher design, the eighth-grade teachers' social studies classes were randomly assigned to treatment or comparison conditions. Teachers (n = 5) taught the same instructional…

A multi-cohort cluster randomized trial was conducted to estimate effects of rich vocabulary classroom instruction on vocabulary and reading comprehension. A total of 1,232 fourth- and fifth-grade students from 61 classrooms in 24 schools completed the study. Students received instruction in 140 Tier Two vocabulary words featured in two…

Researchers have demonstrated that cognitive-behavioral intervention strategies--such as social problem solving--provided in school settings can help ameliorate the developmental risk for emotional and behavioral difficulties. In this study, we report the results of a randomized controlled trial of Tools for Getting Along (TFGA), a social…
