To determine how useful a computerized text editor would be in helping students to revise their papers, an interactive text manipulation system (Wylbur) was made available to two classes of freshman composition students at the University of California, Los Angeles. Since the course received no advance publicity, students did not know when they enrolled that they would work with a computer. Analysis of student responses to a questionnaire about their experiences using the editor revealed the following: (1) too much extra time was required of them to use the word processor; (2) most reported Wylbur was at least manageable; (3) the single most frequent complaint concerned long lines and the apparently endless wait for a terminal; (4) the process for learning how to use the computer was often frustrating and cumbersome; (5) students preferred Wylbur to a typewriter and found computer-assisted revision easier and faster than manual revision; (6) most confined themselves to simpler procedures, overlooking commands that might encourage wholesale revision; (7) time limits/restrictions and expense discouraged full-scale revision; and (8) the system helped poor typists by allowing easier typographical correction and poor proofreaders by offering not only easy mechanical revision but also a fresh view of the text.
