But slides have one big advantage: they can be posted online for later review so students can follow the lecture instead of taking notes.

I think it's even better if the slides are posted prior to the lecture so that interested students can make their notes annotations on the slides - this allows them to fill in trouble spots while not having to copy down all the material (I find it distracting to try to rush to copy everything down, personally).

I had a math instructor record his blackboard lectures and posted them online later that day. Just another consideration.

If the professor just recorded the lecture, I'd imagine most students would never go to class again.

If no one goes to the physical classroom why not sell the same recorded lecture to a thousand people online instead of the 100 that fit into a classroom?

Or better yet, give it away for free!

I had a world history/geography/current events kind of class in college that had an in-person lecture and was also livestreamed and recorded. Lecture hall fit about 1800 people but he also had an unlimited class size "online" section you could sign up for if you didn't get in-person section during early course request. You never actually had to go to class. The professor had to get his own system for taking quizes and handing in assignments since the online learning management system the school used would choke with that many students at once trying to submit things.

Content aside, it was a very interestingly run course. Assignments were at your own pace, you had a large list of the kinds of projects you could turn in for credit. There were quizzes, exams, essay topics, interview topics, and an option for independent projects to get credit. Each kind of project had it's own maximum point value it would be graded out of and the final grade was totally based on how many points your actually earned, not out of how many. Even if you did a shit job on every assignment, as long as you did enough of them, you could get an A. It was a nice way to boost the GPA from just sheer effort rather than actual achievement.

As someone in college who has had their classes recorded and posted online, I still go to class because its dedicated time to my brain. There is nothing else I should be doing other than being in class.

The people who don't show up would have not showed up class recorded or not. It is very useful though when you have a morning class miss or be dead tired and not pay attention to re-watch the lecture to get a better understanding.

It seems like whatever recording either I or the professor make are actually useful to me later on. It's always the classes I don't record are the ones I always need.

All the math tutorials I watch are on youtube at a virtual blackboard! They draw them out just as parent was describing.

So can copies of handwritten lecture notes.
