(62,534 posts)Some people attend classes because they're interested in the field, others attend classes because they have been told that field will benefit them in some way financially in the future.
When you have nothing in particular to gain (no credit for the effort expended) and when you're talking about a general course such as an intro to physics, people are going to bail as soon as they are challenged. They have nothing to lose. It is effectively a waste of time.
Indeed, looking at the demographics of those who joined this class, many of them already have a high level physics background, and it seems as if those people signed up to see what the course was going to be like, found it boring and moved on.
I don't think it's necessarily connected to labs because this sort of "drop out rate" for MOOCs is pretty much seen across the board.
So don't make them mandatory, and just make them available, everyone wins.
