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).
While the body of the essay should generally include objective information, the conclusion should include one or two sentences articulating the author's opinion. This stance should not be conveyed using an "I" statement, which is usually not recommended in formal writing. For example, a sentence relating to the thesis statement comparing life in the city versus life in the country could be, "For these reasons mentioned above and others, life in the city is more advisable for individuals for whom a better quality of life is non-negotiable."
