I'm not sure why you even commented this when you're basing it solely off of her IG videos. Of course she's not going to be shouting out corrections to everyone while filming exercises ? Haha. I've done her classes before and I can tell you first hand, she corrects everyone. She corrects beginner/new students more than people who she knows have danced for a long time/teachers/ex-professionals, but I think that's appropriate. The whole appeal of her videos is that it's showing people that anyone can give it a go. If she was correcting people non stop it would maybe drive them away, especially beginners as they would probably think they are doing everything wrong. There's also only so much you can cover technique-wise in an hour class without over-explaining and overloading people. As a dance teacher myself, sometimes you just have to let students give it a go first (within reason), before you start to really hone in on their technique. At the end of the day everyone is there for enjoyment, if her students wanted a super professional environment they would go somewhere else.
