Similarly, Yutdhana (2010) carried out a study on the application of a wiki to promote collaborative writing. In her experiment, twenty third-year undergraduate students were selected as the participants. The students were organized into five heterogeneous groups of four members. Each group was assigned to do a piece of writing project on a wiki operated on Moodle, specifically designed for the class. Edits and changes of content were tracked using wiki logs. Once the students’ project was accomplished and successfully published on the wiki, students were required to take a two-hour timed writing test, individually. Students’ test was, then, evaluated by two raters using analytical scoring. The results revealed that there was a high correlation between the students’ use of wiki for editing their work and their writing test scores. Moreover, collaborative writing through the wiki had positive effects on students’ perceptions and performances.
