"First year composition programs, whose mission is to provide students with the academic metadiscourse needed to negotiate the discourses of the different disciplines, are generally too marginal, low in prestige, and lacking in intellectual focus and coherence to carry out this mission. I've found that students in my composition courses see them not as a guide to their other courses but as one more hurdle among others to get over."
Gerald Graf: "Our Undemocratic Curriculum." (MLA Profession 2007)
Maybe not entirely related, but at least interesting. Maybe profs (grad students) who are forced into restrictive and regimented teaching formats conduct classes without that enthusiasm necessary to get undergrads excited about learning composition.
