A few years ago I was fortunate enough to attend a seminar given by Penny Gardner on the Charlotte Mason method of homeschooling. I had already read every book on the subject that I could get my hands on (including Mason's original books), but Penny's presentation made it all concrete. After listening to her explanations and personal experiences and watching her demonstrate some of the concepts, I could actually picture myself doing narration, picture study, nature journals, etc.
This Study Guide is like a little summary of the seminar. Penny pulls together many helpful excerpts from Mason's books, and organizes them topically to provide a clear synopsis of each academic subject and element of a Charlotte Mason education. I consider it the best quick introduction to this homeschooling method, and also a useful guide for implementing Charlotte Mason's ideas.
