ABSTRACT
Knowing where to begin this chapter and what to include is difficult. There are so many topics to be covered. What is the best order? What background information will the students possess? Should topics be integrated in this discussion? You are expected to blend topics as you teach by relating one to the other. Perhaps this discussion should follow an integrated format. Still, if that is done, continuity will be next to impossible. This comment brings to mind the story about an individual wanting to borrow a chainsaw. The request was made and the response was "No." Rather stunned, the individual followed with "Why not?" "My dog is sick," was the reply. "What does your dog being sick have to do with my borrowing your chainsaw?" was the next question. The response was "Nothing, but I don't want to lend it to you and one excuse is as good as another." The moral
of that story is that no matter what order is selected, others could serve equally well.
