Existing reviews address important questions about subsets of practitioner training studies in special education but leave important questions about the broader literature unanswered. In this comprehensive review, we identified 118 peer-reviewed single-case-design studies in which researchers tested the efficacy of practitioner training on…

Optimal levels of treatment fidelity, a critical moderator of intervention effectiveness, are often difficult to sustain in applied settings. It is unknown whether performance feedback, a widely researched method for increasing educators' treatment fidelity, is an evidence-based practice. The purpose of this review was to evaluate the current…

Since the first review of alternate assessment literature by Browder, Spooner, Algozzine, et al. (2003), educational research related to alternate assessment has rapidly expanded as state and federal policies have required the inclusion of students with disabilities, including students with the most significant cognitive disabilities, in state and…

Determining evidence-based practices is a complicated enterprise that requires analyzing the methodological quality and magnitude of the available research supporting specific practices. This article reviews criteria and procedures for identifying what works in the fields of clinical psychology, school psychology, and general education; and it…

Meta-analysis techniques were employed to integrate statistically the findings from 74 studies on early intervention with handicapped preschoolers. Findings indicate that early intervention produces positive sizeable effect size; that longer, more intense programs are associated with efficacy; and that little support was found for commonly held…

The article critiques a 1987 (Kavale and Forness) meta-analysis which concluded that research does not support modality-based instruction. The study is faulted for its selection criteria as well as its failure to consider demographic differences, achievement level differences, multiplicity of preferences, definitions of terms, effect-size…

This response to Dunn (EC 221 793) reaffirms the conclusions of a meta analysis on modality-based instruction, through elaboration of the study's selection criteria and methodological factors. Although modality-based instruction is seen to be intuitively appealing, educators are encouraged, instead, to apply instructional methods of proven…

The article reviews the research on effects of cooperative learning on the academic achievement of students with handicaps. Findings of the 12 studies meeting the selection criteria were inconsistent. (Author/DB)

This article discusses probable explanations for the weak effects in some meta-analyses that have investigated the effectiveness of social skills training (SST) for students with disabilities and offers specific recommendations for designing and producing more effective SST interventions. Treatment integrity issues, assessment issues, and…

This paper reviews 31 studies which directly compared two or more instructional strategies used with students who display moderate to severe handicaps. The efficiency and effectiveness of 13 strategies are reported, including error manipulation strategies, response prompting strategies, naturalistic teaching strategies, and stimulus modification…

Thirty-two qualitative investigations of co-teaching in inclusive classrooms were included in a metasynthesis employing qualitative research integration techniques. It was concluded that co-teachers generally supported co-teaching, although a number of important needs were identified, including planning time, student skill level, and training;…

Application of systematic research synthesis procedures to 28 studies of general education teachers' attitudes toward inclusion indicated that, overall, about two-thirds of the teachers support inclusion. Their support, however, varied depending on the disability. Only one-third or less believed that they have the time, skills, training, or…

A literature search identified 39 studies assessing modality preferences and modality teaching. The studies, involving 3,087 disabled and nondisabled elementary/secondary level subjects, were quantitatively synthesized. Subjects receiving differential instruction based on modality preferences exhibited only modest gains. (Author/JDD)

In the context of a discussion of the use of meta-analysis techniques, two articles take issue with the findings of Casto and Mastropieri concerning effects of early intervention, in particular age-at-start parent involvement, conceptual and methodological problems. The authors of the original article provide rebuttals to the critiques. (JW)

A meta-analysis of 20 studies (1975-1995) indicated positive effects for alternative grouping formats for teaching reading to students with disabilities compared to whole-class instruction, particularly for student pairing. In addition, analyses indicated that outcomes for students involved in cross-age tutoring varied significantly by students'…
