Wendy,
You point a difference in the challenges in OL vs on-ground classwork. True the the dynamics are different, even though the content may be identical. My solution is perspective. If we say student learning is the goal, then in both settings this can be accomplished, perhaps with different resources, delivery methods, or course work assignments. Both are valid (in my opinion), just different, and we need to learn to adapt to the delivery model being used.
