Sentence Composing
I found this chapter highly intersting. It details four concepts to use in order to teach students how to be good writers. It is easy to see how the four concepts of unscrambling, imitating, combining, and expanding can be very effective in the classroom.
I see how this would teach students the mechanics of good writing as they need little knowledge of grammar, they just learn how to construct good sentences. I imagine teaching some aspects of grammar will need to be a focus in conjunction with this method.
