Advanced writers are often frustrated by the differences between their work and that of other students in heterogeneous groups. Advanced writers need enriched writing experiences, not more writing experiences. Assignments in W140 should offer broader and deeper experiences that are likely to require more pre-writing and drafting time than W131 assignments.
Advanced writers are likely to be advanced readers.
The choice of a nonfiction book should be based upon the reading level of that book as well as the interest level for students who are likely to have read more broadly than most W131 students.
