I tagged a recent review of The Old Schoolhouse magazine's online edition, "the best just got better". That's not exactly true -- at least not for everyone. Yes, in my experience, The Old Schoolhouse magazine is the best of its kind on the market. That's a lot coming from a guy who's, well, a guy. It's also a lot coming from a guy who has written for some of their "competition."
There are no incredibly bad national homeschooling magazines. However, when my wife got her hands on a sample copy, she was impressed and she encouraged me to read it She pointed out that it was far more practical than others we have read in the past. She was right! Like most homeschool magazines, TOS is somewhat theme oriented. However, it still manages to give ample treatment to curriculum teaching methods and other things of interest to home educators with some of the most innovative ideas I have seen.
