David, This is a great way to customize your instruction for each class. You are targeting the needs of the current students while still providing the content in a sequential manner. I start in a week teaching five sections of the same course and I really appreciate your comments in relation to how each type of instructional delivery can be conducted to keep students engaged. I use a model much like this so I stay fresh for each section since even though I have been through it before this is the first time for each student. Gary Gary Meers, Ed.D.
