Um.... you really do not want to get Winter's dander(uff) up about homeschooling. I personally have nothing against it and respect those who do because I do see it as a viable choice. I appreciate the ones we have around here.
But I do agree completely with your statement about involved parents. Make that TWO involved parents. It all starts in the home.
But this is a fact. Homeschooling, done right, is the best situation for any child. It is one on one with instant feedback in an comfortable environment. Done wrong, it can be a nightmare beyond all imagination. Several years ago, I had a student who had been "home schooled" her whole life. She was almost non-verbal. Her expressive vocabulary was under 500 words; her receptive was somewhat larger. The local child protective services had taken her from her parents. She screamed when she saw crowds of kids; she ran down halls yelling at the top of her lungs. It was a nightmare for her and everyone else. About 6 weeks into her 6th grade year, she was institutionalized for repeated suicide attempts.
I don't care whose feathers I ruffle. You know if you do a good job. Keep on doing it. But don't stick your head in the sand and pretend that every parent out there is good and righteous because some use the excuse of "homeschooling" as a dodge for abuse.
From what I've read here at FR, these are good people who do the right thing day after day. That's great. Wish we could clone them.
