As an aid to Miami-Dade Community College's writing instructors, this report describes the use of the Response System with Variable Prescription (RSVP) Program for Immediate Analysis of Writing, a software package designed to produce feedback statements in the form of personalized letters that reinforce student learning and help correct writing errors. The report first outlines the history of the RSVP Program and then describes the four levels of feedback statements provided by the system; levels A (basic), B (intermediate), and C (superior) provide corrective prescriptions for 156 mechanical and rhetorical errors, and level P (primary) provides non-prescriptive explanations of basic writing concepts such as sentence structure, verb tense, and the use of pronouns. Examples of feedback letters generated by the RSVP system, including welcome letters, assignment feedback letters, status reports, and final reports, are then presented, followed by guidelines to be used in determining the appropriate level of feedback for each student. The report concludes with examples of student essays representing each level of writing skill. Accompanying each essay is an illustriation of an appropriately marked computer card, and an example of the kind of feedback letter the student would receive. (JP)
