The document discusses important elements to consider when setting up instructional contexts for students with autism spectrum disorder (ASD), including arranging the physical environment, establishing temporal structure, using visual supports, providing systematic instruction, accommodating sensory needs, facilitating engagement, establishing stimulus control, and priming. Some key recommendations are to use furniture to provide boundaries, implement visual schedules, collect data to evaluate instruction, incorporate student interests to engage them, and allow choices to give students control. Priming activities beforehand also helps students familiarize themselves and predict tasks.
