Try the following thought experiment. Imagine yourself and an identical twin sibling with equal background knowledge and capacity, facing the same test in two weeks time. You are assigned to a lecture course on the topic and your sib to a small group course. The test is important for both your careers. What will you do to pass? Won’t you both invest at least as much time as necessary to make you feel confident to pass the test? No matter what education is given. To put it even clearer, if your first lecture turned out to be chaotic, wouldn’t you feel urged to skip the class and study hard to understand the material? And would your brother or sister, who may have attended some useful group sessions, be confident that not as much extra time is needed to prepare for the test? Or perhaps she, noticing how much effort you are putting in, may redouble her efforts, even though, if you weren’t around she might have been satisifed with her mastery.
