The purpose of this study was to explore the benefits of cooperative learning in weblog networks, focusing particularly on learning outcomes in college writing curriculum integrated with computer-mediated learning tool-weblog. The first section addressed the advantages of using weblogs in cooperative learning structure on teaching and learning. Attention then turned to issues of opportunities to participate in writing class. For the purpose of this study, the number and content of text contributions made by group members in the blogs including the online responses or asynchronous communication were analyzed. Results indicated that two thirds of learners agreed that using asynchronous communication improved the students' academic development. The benefits of cooperative learning within weblog networks in terms of learner autonomy, cooperative learning, and time management were then illustrated. Educator should stress on the emergence of the insights regarding how technology meets and supports the needs of students. (Contains 1 table and 1 figure.)
