Of course. First, we gotta begin with staff selection. Most schools, even private ones for that matter, are filled with not so much incompetent teachers but certainly teachers that aren't as knowledgeable about their subject and didatics as they should. Next, we gotta change the grading. That enters in the didatics section but I find it important enough to give it a second mention. Kids should try learning not to earn grades, but to simply learn. Learn how to be a better person and learner. My idea is to have them do tests, write assignments, make presentations and so on just for the sake of doing it, with the teacher evaluating them in terms of effort and behavior. Lastly, comes the content. I saw someone suggesting how to write checks and other valuable citizen skills. Content should be more usable by the students, but they should have some rigor to them. So check writing and etiquette wouldn't be taught, neither would be telling the years wars happened, but telling why wars happen
Why writing a check and being polite is relevant, that's stuff that should be taught.
