Teacher-Implemented Modified Schema-Based Instruction with Middle-Grade Students with Autism and Intellectual Disability

A growing body of literature supports the effectiveness Modified Schema-Based Instruction (MSBI) to improve mathematical problem-solving for students with autism spectrum disorder (ASD) and intellectual disability (ID). MSBI is an intervention package that teaches identify problem structure use a heuristic solve word problems. Previous research has primarily implemented in one-on-one setting researcher as interventionist. This study aimed investigate effects teacher-delivered small group format on multiplicative skills six middle school ASD/ID well their ability generalize from problems video-based Results multiple probe across participants design indicate functional relation between problem-solving, but generalization varied maintenance was limited two due coronavirus disease 2019 pandemic closures. Implications practice future are discussed.
