In my opinion there is no replacement for classroom lectures; however, it would be useful if they were videotaped. Sometimes I miss things said by the Professor or would find it useful to simply hear it again. Currently I would have to either have time to stay after class and ask the question or go to office hours. Additionally, as a student who has been seriously ill during the semester, I have found that the most difficult part about getting sick isn't the health problems, but rather the amount of effort and proactivity that it takes to get caught up. Lecture notes for every class aren't always up to par and it can be hard to follow the notes of other people. There have been several instances where I could have easily followed a live stream but was unable to physically walk to class. A wider availability of videotaped lectures would most definitely aid sick students in their quest to stay on top of course material while feeling under the weather.
