During its two and one-half years of use, a computerized text editor has proven to be a helpful revision tool for a freshman composition course. Student feedback has helped to overcome initial problems with the system. A streamlined learner's guide, for example, that made formal training in using the computer unnecessary and increased student willingness to experiment with their writing, was created to replace an earlier, overly complex guide. A sequence of simple assignments demanding a progressively more complex computer vocabulary was found to keep students' attention focused on the writing rather than on mastering the computer. A number of problems, however, still remain, among them, restrictions on computer use imposed by the small number of terminals available to students and the high cost of operating them. Student reactions to revising on the text editor have been mixed: about half the students felt that it inhibited revision while the others believed it made revising easier. Most felt, however, that it was a helpful typing and proofreading aid. It has also been used successfully in helping students analyze their writing style and evaluate organization strategies. The large number of positive student reactions suggests that a more flexible system could become a powerful teaching aid. (MM)
