What are the best scholarly books available on homeschooling?
This is, of course, a matter of opinion. The two that I have found most helpful are Kingdom of Children by Mitchell Stevens and Homeschool: An American History by Milton Gaither. Look here for a fairly comprehensive list of scholarly books. In addition, there are hundreds of other books written by homeschool advocates and homeschoolers themselves who mix research, personal experiences, and how-to advice.
