That's a very good point.
With the self-learning modules, you need to mostly put basic stuff in, stuff that isn't very confusing and that they can get on their own. Then you bring them back—in my case, in the lab, or it may be at the patient's bedside or something—and then, when they're all working together, I usually wait, if someone is making a mistake, for the group to see whether they can correct it. We are all based on problem-based learning, which shows that if someone is in front of the problem, they learn better than if you just give them the answer right away. So we try to go with problem-based learning. We do that also in the small group sessions we have.
But then slowly, if they're really all going to the wrong side, you have to bring them back. You need facilitation.
