The Effect of Collaborative Writing on Iranian EFL Learners' Task Achievement in Writing and Their Perception

Collaborative writing has gained interest in the last decade; however, as stated by Shin, Lidster and Sabraw (2016) more research is required to delve into various aspects of this multifarious class activity. This true experimental research examined the effect of writing collaboratively on task achievement of Iranian EFL learners in writing. Oxford Placement Test was given to 60 language learners in the city of Kashmar, Iran, as the test of homogeneity. Considering +/-1 standard deviation of the mean score, 40 learners were chosen to pursue the purpose of the study. These learners formed an experimental group and a control group with 20 participants in each. Collaborative writing was implemented in the experimental group and individual writing was used in the comparison group. The participants in the experimental group were later interviewed and their perception toward collaborative writing was investigated. The findings of the study through t-test revealed that the experimental group participants outperformed the ones in the control group in terms of task achievement. In addition, the results of the semi-structured interview through thematic analysis revealed that most participants found collaborative writing effective in terms of motivation, peer feedback, comprehensive view over the topic, changing ineffective writing habits, and vocabulary learning; though peer authority and teacher authority were considered as inhibiting factors. Pedagogical implications are discussed.
