Home schooling, like anything, must be done with balance. It is a wonderful thing in my opinion. But it can't be done in a way to isolate the child from other children.
I've known several people who have home schooled and it was very successful. They made sure the kids got a well rounded early education, provided lessons in some sport or activity where they were with other kids. One of my friends got her son Karate lessons, another got her son fencing lessons, and another put her daughter into soccer, and another put both of her children into ballet lessons. All of these children were given choices, so they got to learn what really excited them.
They had the additional advantage of many field trips to museums and sites of interest.
Of course the parent who home schools must have an idea of what learning is about, and recognize that a well rounded child means having a well rounded education and a variety of experiences. It can be done, and done a lot better than public schools.
Unfortunately, JW parents too often use home schooling as a means to isolate their children from the "world" and those children develope an emotional handicap.
Don't cast away home schooling out of hand too fast. It's a terrific thing if done well.
