The approach that most schools use today is called "process writing," which relies on brainstorming, free writing, revising, and peer critiquing to arrive at an acceptable piece of finished writing.
The problem with process writing is that it does not actually teach how to write. Rather than showing the students how to achieve the fundamentals of sentence variety, paragraph development, organization, and detail before they begin to write, the process writing method expects them to somehow arrive at competency through time-consuming trial and error, multiple drafts, and the advice of their peers, who are often no more skilled than they are.
Writing Whatever graduates have a huge head start when they sit down to write. They know how to write great sentences the first time, not the tenth time. They know how to organize their ideas, how to choose the right words, how to punctuate, and how to edit. They achieve better results, faster, and with far less pain and frustration. The self-esteem that comes with such accomplishment is immeasurable.
