Rick VanDeWeghe writes of modeling: "teachers show how they go about the processes of reading and writing-drawing students' attention to the ways readers and writers think and the real decisions they make, especially when they themselves are challenged." In her book Conversations , Regie Routman explains why this modeling process is so successful: "It has always been our job to teach directly and explicitly in response to students' needs-carefully demonstrating, specifically showing how, clearly explaining. Whatever we want our students to do well, we first have to show them how. Of all the changes I have made in my teaching, adding explicit demonstration to everything I teach has been the single most important factor in increasing students' literacy" (24).
Plan B: Use Plan B if you have only a few, larger similarities or differences. After your introduction, in the next paragraph discuss one similarity or difference in BOTH works or characters, and then move on in the next paragraph to the second similarity or difference in both, then the third, and so forth, until you're done. If you are doing both similarities and differences, juggle them on scrap paper so that in each part you put the less important first ("X and Y are both alike in their social positions . ."), followed by the more important ("but X is much more aware of the dangers of his position than is Y"). In this format, the comparing or contrasting goes on in EACH of the middle parts.
