This systematic review and meta-analysis appraised and synthesized mathematics interventions research addressing rational number concepts for students with mathematics difficulties (MD) in Grades 3-9. Included studies (n = 28) meet the What Works Clearinghouse Group Design standards (Version 4.0) for study quality. Across all studies, we found…

Each of the five articles in this special issue gets "into the weeds" in terms of studying actual classroom or school implementation of evidence-based or promising practices. Virtually all confront the issue of logistics and establishing an infrastructure for ensuring adequate implementation. In general, those studies that ask teachers…

Conclusion about site-specific determinants of educational outcomes of the controversial longitudinal evaluation of the Follow Through programs (1976) are challenged again by reexamining the Direct Instruction model data. Reanalysis confirms earlier critiques and supports more recent research funding on the relationship between types of…

This article reviews key findings from school-reform studies of the 1980s on sustained use of effective teacher practices in the classroom and explains their relevance to special education. Recent findings are also highlighted and unresolved issues are identified. An appendix lists sustainability factors and issues. (Contains references.)…

This paper reviews both the content and the methodological issues involved in the small but growing number of empirical studies on the use of Direct Instruction programs and teaching procedures with special populations. The research reviewed includes experimental and quasi-experimental work, summative evaluations of entire programs, and…

This article presents research-based examples of effective instructional approaches for improving the quality of stories and essays written by students with learning disabilities. A common goal of the studies examined was to teach students how to organize writing tasks, generate ideas about the writing topics, and produce final written products…

As a first step in developing a research program that united several individual strands of comprehension research, this paper describes studies that relate to the effectiveness of direct instruction. Various sections of the paper discuss the following topics: (1) variables in the direct instruction model, (2) teacher performance variables, (3)…

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…

A solid, emerging research base exists on how to provide meaningful access to the general education curriculum for students with learning disabilities. This article uses examples from research in comprehension and writing to highlight the underlying features of these empirically based approaches. The importance of multiple teaching strategies is…

This review of research considers how best to teach English-language learners. A realistic appraisal of the empirical database indicates that research findings have failed to provide answers to questions about the importance of native language instruction and the best age and best methods for introducing academic instruction in English. The review…

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%…

Reviews the results of a 1991 U.S. Department of Education report entitled "A Descriptive Study of Significant Features of Exemplary Special Alternative Instructional Programs." The features of nine exemplary special alternative instructional programs are described that appeared to contribute to positive outcomes for students from diverse…

The current state of the knowledge base on the effectiveness of specific instructional practices for English-language learners was examined by conducting an exploratory meta-analysis on eight studies of instructional interventions and using qualitative synthesis to supplement this analysis. The first data source was the eight intervention studies…

This guide provides practical information for teachers and others working with students who have learning difficulties (such as learning or language disabilities) and for whom English is a second language. Emphasis is on productive instructional strategies and approaches. The book is based on results of focus groups comprised of practicing…
