Educating Students with Intellectual Disability and Autism Disorder is a comprehensive resource, providing educators with the most up-to-date information on what works in real classrooms with real students. This first book in the four part series, provides a comprehensive explanation of the four learning stages–acquisition, fluency, maintenance, and generalization–and how understanding this process can help educators plan instruction. The authors (who are also editors of the series) provide the reader with essential guidance on how to find and identify the best research- and evidence-based practices and then implement these practices with fidelity.
