Above and beyond the specific materials that inform the selection and evaluation of goals and objectives, it is important to understand how particular strategies will be used to create a guide for ongoing skill development. It is not sufficient for a teacher to know what skill comes next in a sequence, but to understand how a particular skill or goal fits into a broader conceptual or skill development picture, and lays the foundation for functional skills and activities relevant to each student’s life. The teacher must become her own classroom scientist, doing exploratory studies with a child to identify the best strategy for teaching specific skills for the individual child. When a child fails to make progress with one strategy there are others to try and the most effective interventions are the ones that should become first choice for introducing new but related tasks.
