I'm not a parent (and older), so my views and knowledge aren't as broad as many, but when I was in school the parents never came in to monitor the class. I just remember in kindergarten, when it was your birthday, the parent was allowed to come in and bring cupcakes or goodies for the whole class and a little celebration was held....and of course the yearly "open house" where the teachers would present what the kids had done or were studying, etc. I can't remember what that's called..... but it was in the evenings. Then the regular PTA meetings.
IMO, it would be a distraction for the children if parents were allowed to come in anytime and sit in on their schooling, That's one job of the principle, the superintendent and the school board to oversee. A parent should be able to get an idea of how things are going by just communicating with their child about their day..and other parents. That's the transparency that needs to take place. Kids also need to have some kind of trusting relationship built with the teacher while there. I know in today's society it's scary, but it still needs to be there. For the most part, it's a structured and controlled environment. I'd be more concerned about the other student's behaviors reaching my child before a teacher's. Well, at least during regular school hours. Extra curricular activities or school trips would be another matter where my focus would shift to the teacher/coach or whoever was in charge. JMO
