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).
There are no hard and fast rules about organizing a comparison/contrast paper, of course. Just be sure that your reader can easily tell what’s going on! Be aware, too, of the placement of your different points. If you are writing a comparison/contrast in service of an argument, keep in mind that the last point you make is the one you are leaving your reader with. For example, if I am trying to argue that Amante is better than Pepper’s, I should end with a contrast that leaves Amante sounding good, rather than with a point of comparison that I have to admit makes Pepper’s look better. If you’ve decided that the differences between the items you’re comparing/contrasting are most important, you’ll want to end with the differences—and vice versa, if the similarities seem most important to you.
