The first quiz asked what the instructor needs to manage a class effectively. One option was "have a plan and stick to it". But the correct answer was "have a variety of learning activities to offer". I agree that this promotes effective class management, but I would respectfully suggest that having a plan promotes effective class management *better* than varied learning activities.
Let me put it this way: Having the students do one or two boring assignments in an otherwise engaging course is far less damaging to classroom management than not having a plan.
Though I do agree that the "stick to it" part is not critical, and if that was their point then I agree. It's good to have some flexibility in your plan so that you can adapt based on student input and other discoveries in the classroom.
My two bits anyway.
