A Meta-Analysis of Performance Feedback as an Evidence-Based Practice in Special Education Teacher Preparation

Abstract

This meta-analysis systematically examines the evidence supporting the effectiveness of performance feedback as an evidence-based practice in the training of preservice special education teachers. A total of 27 studies were evaluated using the rigorous What Works Clearinghouse (WWC) design standards for Single-Case Experimental Research. Results indicate that 15 studies, encompassing 56 preservice special education teachers, met the WWC design standards with and without reservation. The weighted aggregated mean treatment effect estimates were .91 (Tau-U) and 2.59 (Between-Case Standardized Mean Difference), demonstrating a strong impact of performance feedback interventions on enhancing preservice teachers' instructional practices. This study contributes to the extant literature by providing robust evidence supporting the classification of performance feedback as an evidence-based practice for preservice special education teacher preparation, meeting the stringent criteria set forth by the What Works Clearinghouse (WWC). Analyses also include methodological quality, risk of bias, and treatment effect estimates, addressing key gaps in extant literature and supporting recommendations for future research. The findings highlight the potential of performance feedback to shape effective teaching behaviors among preservice special education teachers.
