This study investigated the effectiveness of an approach to improving revising skills that integrated strategy instruction, peer response, and word processing. Seventh and eighth grade students with learning disabilities were taught a systematic strategy for working in pairs to help each other revise their writing. The strategy was designed to guide students in both the social and cognitive aspects of response and revision. Cognitive support included a set of evaluation criteria, specific revision strategies, and an overall strategy for regulating the revision process. Social interaction was guided by a predictable structure for listening and responding to each others’ writing. A multiple probe design across pairs was used to assess instruction. On the pretests, students made few substantive revisions and did not improve the quality of their papers by revising them. Following instruction, all students made more substantive revisions, the proportion of revisions rated as improvements increased from 47% to 83%, and second drafts were rated as significantly better than first drafts. Furthermore, the overall quality of final drafts increased substantially from pretests to posttests. The gains were maintained at one and two-month maintenance testing and generalized to handwritten compositions.
