Collaborative Writing

One of the most challenging aspects which language learners face is vocabulary development. Therefore, helping the learners master the target language vocabulary is of vital importance. Using collaborative writing tasks to help students achieve this goal and to see how it impacts their vocabulary development was the subject of this research. To this end, the researcher selected forty female high school students and divided them into two groups: an experimental group and a control group. A pre-test and a post-test were conducted on both groups. The design of this study was quasi-experimental intact group design with pre and post-test control and experimental group. Statistical analysis of test results showed that collaborative writing has an impact on the development of the vocabulary of Iranian high school students.
