Teachers should be allowed the opportunity to request contextualized guidance when they need it. Educative hints provide teachers with ideas, for example, about not just how to enact instructional moves but also the rationales behind particular instructional decisions within a specific lesson (Ball & Cohen, 1996)

Teachers need to use and adapt curriculum materials for their own classrooms, and understanding the reasoning behind particular instructional decision helps them make productive changes. This is especially important, of course, for new teachers.
