John Taylor Gatto is well known in the homeschooling movement. He was named teacher of the year in 1991, and at that time the Wall Street Journal published an article of his in the Op-Ed section in which he announced he was quitting teaching, claiming that he was no longer willing to hurt children. He has written and spoken extensively about the absurdity of modern public education.
His website is here:
and a site with videos of him speaking about various topics is here:
One of the most useful videos I viewed had him suggesting that the best way to become a good writer was to just write- anything, anywhere, any amount. I adopted this for my own kids, who are asked to write between 1 and 2 pages a day. I don’t care if they write a story, a rant, a menu or whatever. The way to get good at writing is to keep doing it.
