It would be great if the material offered in the online classroom—posted lectures, textbooks, other course resources, and our feedback on assignments—were enough to give each student the information necessary to understand and embrace all that is being taught. But we know this rarely happens. Rather, we must intervene continuously to explain; clarify; unscramble; and show concepts, ideas, information, formulae, and systems. While doing this may seem easy, to be most effective at student intervention several approaches must be considered.
