I am very new here, and will gladly apologize if I step on toes. But the tone of this post really is unkind. In no way am I saying that you are unkind, but I think this was rude and it does not add constructively to the discussion. Even if I disagreed with Bill's view, I would be still be disappointed in the tone here.
Just because you can doesn't mean you should. And it's ok to admit when you are wrong. (I've had to apologize plenty of times!) I'm not going to quote the entire post, as it doesn't deserve repeating, but do you believe your tone was polite and in any way conducive to civil discussion? Sure, I was a huge parenting expert before I had kids, the worst source of parenting advice. But I think he is offering commentary based on what he's done in his journey and it's exciting to hear what his son is learning ... and enjoying. Maybe Bill hasn't raised kids to college age. But I think Bill contributes positively in this forum. He offers advice and his world won't collapse if I disagree with him. And I've never heard him claim to be the ultimate authority on math. Posts from him and others have kept me reading, posts like this are a turn-off. But, you may disregard me since I'm not even a homeschooler yet, and my kids are not as old as yours.
:lol:
Now, back to the article. I agreed with a few points (not letting age dictate everything, not letting students progress based on grade level without achievement) but being behind is a real problem and I share those concerns. Just my quick thoughts on it, and I appreciate those who have discussed it thoughtfully.
