Summary
This study examines whether a professional development program helps teachers implement Strategic and Interactive Signing Instruction (SISI) with higher fidelity. The training includes review of an intervention manual, live modeling of SISI components, and discussion of implementation expectations. Teacher fidelity is evaluated with the Strategic and Interactive Signing Instruction Fidelity Tool, which rates the extent to which core components are used during a intervention session. The study also documents how often teachers receive additional support (e.g., coaching) to understand which procedures help strengthen implementation.
