Persistence and progression rates for underprepared, African American, first year students entering four-year colleges is a major concern. With the consistent low persistence, progression and graduation rates of underprepared African American students in both Historically Black Colleges and Universities (HBCUs) and predominantly White serving…

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…

The developing synergy of legislation and research throughout recent history points to the current momentum behind college and career readiness for every student. Researchers have found that embedding academic content into career education improves student learning. Integrated learning can vary in approach and style and can be adjusted to fit into…

Purpose: In this study, the authors examined how signal clarity interacts with the use of sentence context information in determining speech-in-noise recognition for children with cochlear implants and children with normal hearing.

Introduction: Group-randomized trials (GRTs) are one of the most rigorous methods for evaluating the effectiveness of group-based health risk prevention programs. Efficiently designing GRTs with a sample size that is sufficient for meeting the trial's power and precision goals while not wasting resources exceeding them requires estimates of the…

This article reports the results of a follow-up analysis of 779 students with disabilities who participated in group-randomized, control group studies designed to examine the efficacy of self-determination interventions in secondary school to examine the relationship between self-determination status when exiting high school and adult outcomes 1…

The purpose of this study was to evaluate the effect of rhythm and tonality on an academic memory task by comparing three different treatment conditions: a poem, a rhythmic chant (or rap), and a melodic rhythm (or song). A quasi-experimental experiment was designed and implemented, specifically a pretest-posttest-posttest control-group design.…

This efficacy study was designed to examine the traditional FOSS curriculum (Delta Publishing, Full Option Science System/FOSS, magnetism and electricity, structures of life, and water modules, 2005), and the new ASK/FOSS curriculum (magnetism and electricity, structures of life, and water modules, 2005), a revised version of the original FOSS…

The project reported here is conducting repeated randomized control trials of an approach to high school geometry that utilizes Dynamic Geometry (DG) software to supplement ordinary instructional practices. It compares effects of that intervention with standard instruction that does not make use of computer drawing/exploration tools. The basic…

The purpose of this study was to determine the relationship between using computer-assisted instruction (CAI) size and success on the Texas Assessment of Knowledge and Skills (TAKS) mathematics exam with fifth-grade students in Texas compared to the effect of alternative improvement approaches used by a control group.
