Intended for directors and teachers in high school and college writing labs, this booklet addresses their basic concerns about lab programs and the most effective ways to help students improve their writing skills. The 29 essays are arranged under six headings: the one-to-one tutoring process, diagnosing writing problems, tutor training, choosing multimedia and self-instruction, structuring the writing lab, and maintaining and expanding the writing lab. Topics discussed in the essays include (1) problems in tutoring; (2) searching for causes, not symptoms, of writing deficiencies; (3) the importance of role playing and peer criticism in peer tutor training; (4) audiovisual instruction in a writing laboratory; (5) crucial considerations in preparing for a writing workshop; and (6) evaluating a writing lab. An appendix contains examples of writing lab forms, such as referral sheets, appointment schedules, questionnaires, and tutor's reports. (HTH)
