At least at one Med School. The plan is to completely phase out lectures by 2019.
The trend at medical schools is just part of a reform movement in the teaching of science, technology, engineering and mathematics (STEM) that emphasizes active learning instead of lecturing. Research supports the approach. When a team of researchers analyzed 225 studies that compared active learning and lectures in these fields, they found that test scores improved about 6 percent for students in active learning classes and that students in lecture classes were about 1.5 times more likely to fail than their counterparts in active learning classes.
