The tutors' role is not to write student papers, but to help students learn to diagnose and repair their own problems. English 2L is a non-baccalaureate course. The units of credit count toward financial aid's unit requirements, but they do not count toward graduation. While your English 1A or 1B instructor will teach you the principles and strategies of writing essays, the Writing Center tutors will teach you the art of basic sentence and paragraph writing. And it is an art.
Writers are artisans.
Sentences and paragraphs are the basic tools of the writer's craft. All sentences are not, however, alike. Nor are all paragraphs. As an artisan, you need to understand how to choose the right tool for the right job. As you choose sentence forms and compose them into paragraphs, you will need to understand your grammatical and rhetorical choices, the various ways to combine them, and their various rhetorical effects.
