The purpose of this study is to investigate the effectiveness of incorporating dictogloss and dialogue journal activities into middle school writing class with regard to student writing ability and attitude toward English writing. The study was implemented with 95 students in the experimental group drawn from 194 students in total. Study participants were assigned different writing activities and homework every week for a period of 15 weeks. Pre and post writing tests were administered in order to gauge the effectiveness of the dictogloss and journal writing activities. Furthermore, pre and post training questionnaires were provided to the students in order to ascertain whether students experienced a change in attitude toward English writing and cooperative learning. To evaluate students` writings, an analytical scoring method was used. It consists mainly of four categories: content, organization, grammar & vocabulary, and mechanics. Results indicate that the dictogloss and dialogue journal writing activities are effective in developing writing skills and encouraging students to write in English, while promoting positive attitudes toward English learning. These writing experiences facilitated an invaluable opportunity for authentic practice for the learner and lowered anxiety by providing freedom of subject matter and encouraging collaboration.
