Form my own experience, the only thing we noticed BEFORE we started video recording our lectures was that the weakest students tended not to come to lecture. But plenty of good students also didn't go to lecture, so I have no faith that lecture attendance is crucial for med student success. I had plenty of good students who I swear I only saw at exam time.
I have yet to see any published data that shows lecture attended correlates with measure of student success.
You have to figure out what works best for you. Some students do find it helpful to go to lectures.
For those of you with mandatory lecture attendance, you have my sympathies, because as adult learners, YOU know best how to learn. Your faculty haven't figured that out yet, alas. At the least, show them the medical education data that flipped classrooms work much better.
