Rather, a component of instructional leadership must be an ability to know what is meant by quality instruction, an understanding of the local context, and the realization that no one fully controls outcomes. Quotations from an interview with Cuban and from How Teachers Taught explain this perspective. If you really want teachers to . . . change their instruction from A to B, you had better know what A is and B is and that there are strengths and weaknesses to each A and B. There is a history there and you need to be more informed about those traditions of teaching. (Cuban interview, April 16, 2010) (Brazer & Bauer, 2013)
