"What is the point of CM approach?"To create a love of learning in the child.
"Does it truly take 6 hours of outdoor time a day to love the Creator?"No, I definitely don't think 6 hours is required to love the Creator of the nature we're studying. And while I think she was being quite idealistic in even recommending that much time, I don't think her point was that quantity of outdoor time = more understanding, more love, or more academic knowledge.
However, having said that I take that recommendation (to spend that much time outdoors) with a grain of salt, I do find much value in nature study. The point of nature study is to learn science in a real, concrete way. Not reading in a textbook about botony, zoology, or astrology, but seeing and touching and experiencing science in nature. Nature study is how science is done in the elementary years.
"What is the point of all that narration?! "
First of all, narration isn't meant for every single subject and it is accomplished in many differerent ways (telling the story back, acting out the play, drawing the animal I'm reading about, etc.) Each child (at this age) spends about 5-10 minutes total narrating each day. Narration is composition, learned orally before it is learned in writing. Children learn to express their ideas orally first by telling back what they have learned. Then later, when they need to learn how to write an essay, they only have to write out what they have already learned to express and organize. In schools, children have to learn to write out their thoughts before they even know how to organize them. CM figured out that it works better the other way around. I think that's genius.
