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 purpose of this efficacy study was to examine the impact of the Teacher Study Group (TSG) professional development program in vocabulary, on teacher knowledge, observed teaching practice, and student vocabulary achievement, when implemented with first grade teachers in Title 1 schools. This multi-site cluster randomized trial was implemented…

Randomized field trials were used to examine the impact of the Teacher Study Group, a professional development model, on first grade teachers' reading comprehension and vocabulary instruction, their knowledge of these areas, and on the corollary comprehension and vocabulary achievement of their students. The multi-site study was conducted during…

This meta-analysis synthesizes experimental and quasi-experimental research on instruction that enhances the mathematics performance of K-12 students with learning disabilities. It reports the findings from this synthesis, discusses the implications for practice, and suggests next steps for research and professional development efforts in this…

This article focuses on curriculum analysis, an aspect of direct instruction that is frequently neglected or obscured by an emphasis on classroom management and teacher performance. Explicit strategies that are used to teach higher cognitive skills and the importance of teacher training in the appropriate use of direct instruction are discussed.…

Validation of a classroom observation measure for use with English Learners (ELs) in Grade 1 is the focus of this study. Fourteen teachers were observed during reading and language arts instruction with an instrument used to generate overall ratings of instructional quality on a number of dimensions. In these classrooms, the reading performance of…

Presents a conceptual framework for teaching science to students with disabilities. The framework suggests integration of explicit instruction in critical concepts, with cognitively-based approaches that emphasize problem-solving skills on real-world tasks. Implications for policy, professional development, and creation of learning environments…

This brief paper summarizes research on effective instruction in writing for students with learning disabilities. It finds that three components stand out as methods that reliably and consistently lead to improved outcomes in teaching expressive writing to these students. These components are: (1) adhering to a basic framework of planning,…

This study compared two approaches for teaching a history unit on the Civil Rights Movement (1954-1965) to middle school students with learning disabilities (LD) in general education settings. The curriculum was designed to make the content challenging, but accessible. The major text was the documentary, Eyes on the Prize (DeVinney, 1991).…

A multivocal synthesis involving 13 educators and researchers investigated effective instruction for English-language learners and found five specific instructional variables, including: building and using vocabulary as a curricula anchor, using visuals to reinforce concepts, implementing cooperative learning and peer-tutoring strategies, using…

The results from the longitudinal evaluation of over 2000 low income students involved in the Direct Instruction Follow Through Project between kindergarten and third grade are reviewed. Of the ten major education approaches evaluated, students in the Direct Instruction model performed highest in all areas of Math: (1) Computations (66%…

Current research on direct instruction is reviewed with a particular emphasis on studies of instructional design and technology and research on effective staff development. Among conclusions was that the same instructional variables affecting learner performance with traditional materials affect learning with computer-assisted instruction and…

This Practice Guide is the first in a series of the Institute of Education Sciences (IES) guides in education that are developed by a panel of experts. The guides are intended to bring the best available evidence and expertise to bear on the types of systemic challenges that cannot currently be addressed by single intervention or programs. This…

This article summarizes the critical findings of recent research syntheses concerning intervention with students who have learning disabilities. The syntheses examined research on higher-order processing and problem- solving, reading comprehension, written expression, and grouping practices associated with improved outcomes in reading. Principles…

Procedures and strategies that consistently lead to teachers' sustained use of innovative research-based practices are characterized by the provision of both behavioral and technical support and opportunities for teachers to explore the conceptual aspects underlying the research. A case study illustrating these components suggests reasons for…
