Efficacy of Video Modeling and Brief Coaching on Teacher Implementation of an Evidence-Based Practice for Students With Severe Disabilities

Effective professional development strategies are needed to enable special educators to provide evidence-based instruction and support to students with severe disabilities. In this single-case design study, we measured the efficacy of video modeling and brief coaching to enable three elementary special education teachers to implement constant time delay and the impact of their implementation on student progress toward individualized goals. After receiving professional development, all three teachers implemented constant time delay with fidelity and promoted student progress on individualized goals. Teachers were able to identify and correct some of their own implementation errors by revisiting video models after attempting implementation. Teachers reported positive perceptions of the professional development model. We provide recommendations for how video modeling and brief coaching can be used in tandem to promote effective implementation of evidence-based practices.
