My answer is obvious, but I'll leave it here to start with.
We need to reduce the representation of women in education massively. The majority of women seeking these roles have malicious intent, and are actively harming young boys.
We know they don't mark boys fairly, but that's just the peak of the insidious feminist plot.
They've clearly been destroying the self-worth of boys in the schools to groom a new generation of woman worshipping simps.
Right now, I'd be worried enough teachers don't want to submit to that that you'd have an even bigger teacher shortage. I mean if your school district already has a waiting list, then by all means. It's going to be hard to do this in places where teachers have a lot more rights and power than parents. Even if you get a law passed. People do not want to work for these school districts. Anything you do to make their job worse makes staffing that much harder.
And it will make it worse. However I feel about teachers, parents can be just as bad. For certain values of parents, them not watching is a good thing.
A teacher who's doing their job won't care.
A teacher that's indoctrinating children will absolutely protest, because they want to manipulate children and you're taking that away from them.
If teachers leave because they're not "comfortable", there's a high probability that they were indoctrinating children and don't deserve to be "teaching" children.
At the end of the day, for public school teachers, they're funded by tax payers and, therefore, beholden to tax payers. They do not enjoy the same privileges as private institutions.
I would care. If people actually watch and criticize this would quickly get overwhelming. Not just legit criticism of lesson plans. Parents are going to be complaining that their Johnny doesn't get more attention. Parents are going to complain if their children get disciplined. The only mitigating factor I can think of is that the worst parents will probably be the most likely to ignore the videos, but busybody parents are about to become more of a pain.
I like the idea of having video tapes, in case a question arises whether a teacher broke a rule, but I'd rather use them like security footage than a broadcast. We already have a pretty powerful feedback mechanism in that parents get to talk to their children. Sure a child is a bit of an unreliable narrator, but that's something adults can work through. Lesson plans should absolutely be shared with parents.
That's my guess of what will happen, but I hope somebody tries it. If these problems are going to happen, they will happen quickly.
If it were a college, you'd have a point. But it's not college, where a lecture is given and students are expected to to do everything on their won. If a child is failing or doesn't understand the subject material, a teacher has a responsibility to get involved and help them out.
If they don't have a case against the teacher, no disciplinary action against the teacher would be taken. If they do have a case, then disciplinary action against the teacher is warranted.
It's not like children don't talk to their parents about what goes on in the classroom, whether they're telling the truth or not. Many kids have smart phones in class and also record what goes on, but only for stuff that they care about.
Also, it's not like teachers don't deal with bad parents as it is.
Worst case scenarios: cameras wouldn't change anything.
Best case scenario: cameras would tell us who's lying and who's telling the truth.
It's the same thing with cops wearing body cams and that's been one of the best things that's ever happened with law enforcement, for both the public and the police officers.
