A comment from Elders' quorum from a few weeks ago, when we got on the subject of over-protection of children (quoting from memory):
"Before I joined the church I wondered how we were going to protect our kids from the bad influences in the world. We considered home schooling. But then we joined the church and learned that the church is against home schooling because our kids need to experience the social aspects of school."
There was no reaction to this part of his comment and the lesson went on its merry way. If this comment had been made in Relief Society, I imagine the building would have gone up in smoke before the class period ended.
From what I can tell the church has no official position on home schooling, but if anyone knows where this person might have heard of this new revelation, I'd be interested. Of course, I could just ask him myself...
