Shimo-based collaborative argumentative writing: Do grouping patterns matter?

Within the Toulmin model of argumentative structure, this study examined collaboration approaches through Shimo-based co-argumentative writing of students in the student-picked groups and teacher-assigned groups. Students were fourth-year university students majoring in English. The differences between the two groups of students were analyzed, with seven collaboration approaches being identified. Additionally, students in the student-picked groups were more collaborative than the counterparts in the teacher-assigned groups. Discussions were expanded around this result.
