McDonald (2007) investigated how collaborative learning assisted students’ English writing, especially in raising their awareness of language accuracy. In the study, a group of third-year university students were required to construct their own wiki about interesting areas in Sengari University, in English. All of the students were assigned to work in pairs. Each pair was assigned to find information from different resources such as the library, staff interview, and online search. Then, the students were asked to post their information on their wikis. After that, they evaluated their wiki collaboratively to develop it in terms of both content and grammar. Finally, the students were requested to present their wiki to the instructors orally. The findings suggested that the students were motivated in learning via wiki. They also expressed positive opinions towards doing group work. Moreover, the participants reported that working in groups helped them learn how to correct some grammar points in their writing.
