An analysis was conducted of the What Works Clearinghouse (WWC) research evidence base on the effectiveness of replicable education interventions. Most interventions were found to have little or no support from technically adequate research studies, and intervention effect sizes were of questionable magnitude to meet education policy goals. These…

Policy agencies are implementing strategies to increase the use of research in policy decisions. This paper examines the evidence about the effectiveness of these strategies. We conducted an extensive search focused on population health policy and programmes. We classified 106 papers meeting study criteria into research type (conceptual,…

This randomized field trial comparing Strategies for Teaching based on Autism Research and Structured Teaching enrolled educators in 33 kindergarten-through-second-grade autism support classrooms and 119 students, aged 5-8 years in the School District of Philadelphia. Students were assessed at the beginning and end of the academic year using the…

Research can and should inform teaching and learning. The importance of solid research evidence can, therefore, not be underestimated. Unfortunately, significant gaps still exist between research evidence, policy, and practice. The literature suggests there are many reasons for this, including a lack of awareness about the benefits of research, a…

Despite expansive improvements in both treatments and research, the majority of persons with autism use non-empirically supported interventions. One way to decrease the research-to-practice gap involves increasing the direct applicability of research findings to clinical settings. Effectiveness research achieves this goal by identifying treatments…

It is argued that, although thousands of evaluations have been conducted of social interventions, little has been done to cumulate those results to guide intervention architects. Building social intervention theory and meta analyses are suggested as ways to unify this knowledge and make it useful. (SLD)

An examination of the effect of intervention strategies utilized in the Research and Development Utilization (RDU) Program on school improvement outcomes was the subject of this document. The basic Federal/State approaches to support local school improvement efforts are a coercive/manipulative approach, direct support, or indirect support.…

Education researchers, practitioners, and policymakers alike are committed to identifying interventions that teach students more effectively. Increased emphasis on evaluation and accountability has increased desire for sound evaluations of these interventions; and at the same time, school-level data have become increasingly available. This article…

This digest summarizes the research on effects of the full-service school model on students with disabilities. In the full-service model, schools house a variety of health care, mental health, and related services for children and their families. Examples are listed of preventive services, early intervention services, and intensive treatments for…

Discusses factors that influence the selection of treatment approaches in speech-language therapy, the importance of efficacy studies on treatment decisions, the role of parents and families in influencing treatment decisions, challenging the scientific orthodoxy, and trusting clinicians to evaluate the effectiveness of new treatment approaches.…

Because research does not support the efficacy of any single service delivery arrangement for all mildly handicapped and at-risk students, the best approach is to maintain familiar service delivery structures while testing new ones. Direct instruction and behavioral interventions are probably the most effective classroom strategies with most of…
