As a teacher of writing at the high school level, I am always on the lookout for a variety of common sense ways to teach to the many learning styles in my classes. I bought my first "Grassroots' book about 20 years ago. Those books are still valuable and still being used by me and by my students. Since my first purchase, I have continued to go back to Fawcett/Sandburg and now just Fawcett.
There are no gimmicks, no promises here, just the creation of writers whose common sense about teaching writing and writers provides a powerful resource for those who understand the value of the writing process throughout all the aspects of our lives.
