There are lots of Unschooling Christians out there. This book is the first to address the lifestyle that many call incongruous but those of us who practice it find fulfilling and also scriptural. Not a how-to but instead an inspiring encouraging read.
This book was written to confront the idea that "Christian unschooling" is an oxymoron. According to a traditional definition of unschooling, I believe it is. However, the author's notion of unschooling seems to be unSTRUCTURED, as opposed to unDIRECTED. The focus is on facilitating learning, rather than stuffing facts into a child's head. Overall, good stuff!
