Who controls the learning in your classroom?
What are the sources of that learning?
Does the learning happen as a matter of access to content, or participation in teacher-derived learning activities–i.e., units and lessons?
Who or what is the most persistent catalyst in the process of learning?
Frequently, it’s probably you (the teacher). You’re the expert on both content and pedagogy. You know what’s being learned, and how it might be best learned.
