>Covering more material isn’t necessarily a good thing if students are not really understanding the material that’s already been presented. I personally and benefited greatly from others asking questions. Sometimes the questions asked were not even things I considered. In my college classes that were purely lecture based where the prof didn’t allow interruptions, I certainly got more value out of studying with others because of the questions.

Sure, that can also happen. I've had multiple lectures though where the questions caused pacing issues and where the questions were unique to the questioner. It's a catch 22 because the teacher asked for this but still wants to cover the required material, and they need to balance it better to avoid losing control of the class. If in a college or grad school environment, a professor has office hours. If there are multiple students with similar questions, I have found that email or later lecture clarifications work well.

I'd say I got a lot of value out of studying with others regardless of whether questions were allowed. It's a necessity where a professor yells at you for asking a question as did my college statistics professor; unfortunately he was also the head of his department so nothing we could do about it but learn on our own.

That's not the trade-off without penalties for non-participation though. It's not 'no questions at all' or 'all questions, all the time.' It's some people ask questions, most people don't, the grades aren't impacted by your own introverted nature.

Here's the kicker - most of the time, if participation is graded it doesn't massively increase the actual participation in discussion. It just gives the professor more control over the grading, something they desire especially if it's blind grading numbers. It's a penalty system for people that the professor doesn't like or behavior they don't like, and sometimes a way to reward favorites. That's all.
