In a lecture/test format there are around 5 tests per semester. A student doesn't have to keep up each day. The time between tests is around 3 weeks. More if there are fewer tests. Between tests a student can slack off for a couple of weeks. Then spend a week catching. Going to the math center or talking to a tutor. They take the test and then repeat the cycle. Most teachers give practice tests and for the most part it's obvious which type of problems are on the test. Just need to learn those types of problems. The material covered in the class is much more than the few problem types covered on the on the test. Obviously my particular failure doesn't indicate anything. That's why I wrote: "My experience is...." The flaw is that when students don't watch the video it can't be hidden in class. When doing group problems or in when discussion occur it's clear they are lost. It's cleat that the work wasn't done. It's this embarrassment - the confrontation with the reality that they didn't do the work - that is upsetting to them. It causes problems and is a great pain to deal with. I believe that the format proposed only works with motivated students. My belief might be wrong. I don't think it is.
