RE: Collaborative copy editing/proof reading
The only two features of the curriculum I developed for my kids were 1) I brought them to work with me, so they learned to understand things by doing them. They learned math by reading tape measures. Since they got paid, they were motivated. 2) Their interest. If they asked about astronomy, we learned astronomy. If they were interested in American history, or music, or money (all of which they, at one time or another, were very interested in) that's what we learned.
If a child wants to know about something, nothing you can do will prevent them from learning about it. If they don't, they will resent being forced to learn, and that's completely counterproductive to the educational process.
We lived in a remote area, and it was a challenge to provide a means of socialization with their peers, so when they hit puberty I did enroll them in public school for that reason. There are some things parents just can't teach, but kids can only learn by interacting with their peers. That's the human condition.
Upon their initial enrollment they were at the top of their class in every subject, and charged into every possible club, group, and sport they could. I told them they would find the institution of school stifling in time, but they, so thrilled at interacting with their peers, did not believe me.
As time passed, and the schools continually impressed rote learning of material they had no interest in, their eagerness to participate cooled, their grades dropped, and they understood why I had homeschooled them to begin with.
I consider their education a great success, not least because they came to understand misinformation, propaganda, and institutional abuse. I hope you do continue to invest in helping your kid(s) learn about stuff they wanna know, because learning how to learn, and that learning is fun, will be amongst the most important things you can do to prepare them to succeed.
