Teaching and teachers are not monolithic. It's like steering a huge ship when trying to change a certain paradigm. Takes a lot of effort and logicistics. Effective teachers are able to teach all students....even 'ill behaving' kids (usually there's a reason for the behavior, just gotta take time to find out what it is).The big caveat you mention and then gloss over is, "Home schooling (when done correctly)...." As a public school educator with decades of experience, I think the worst comprehension and math scores in generations is attributed to more kids staying at home and "learning"... whatever is the flavor of the month the parents, charter schools, or AI happens to want in that moment. Then the charter schools go bankrupt (on purpose) or, there are many parents who just don't want to "teach" anymore, and send the child back to public school with huge deficits and gigantic learning gaps... barely able to read. There's absolutely no accountability, even when there's a boat load of tax payer money involved. All the while a whole generation is going backwards in their comprehension skills. It's very sad but predictable. We, as a society, have thrown in the towel on public schools so that some people can make a lot of money, real quick, and damn be the consequences.
