Purpose: In participatory approach to second language teaching and learning, students actively engage in their own learning process and collaborate with others (Cobb, 1994; Greeno, 1998) to achieve their goals. Also, collaborative learning has been shown to encourage the growth of student interdependence (Bruffee, 1999), responsibility (Totten, Sills, Digby, & Russ, 1991), interpersonal skills (Rymes, 1997), and cognitive and critical thinking skills (Johnson & Johnson, 1986). Methodology: Adopting a sociocultural perspective, the present study has attempted to explore the attitude of teachers and learners toward the effectiveness of the method. In so doing, 60 Iranian EFL learners from two intact classes participated in the study, in which the learners from the two classes were randomly assigned to one control group and one experimental group. For fourteen sessions, the researcher in the control group class followed her regular teaching practice through the conventional book-based method of conducting an English class. In the experimental group class, however, the researcher adopted the participatory approach tasks and activities, in which she applied various participatory approach-based techniques, activities, role play, and problem solving activities, group work and collaborative tasks in the classroom instruction. Findings: Results of the comparison of the effects of the experimental participatory group and the control conventional group revealed that although the students in both groups improved their scores on the IELTS posttest, there was no statistically significant difference between the experimental group’s overall performance and that of the control group. Conclusion: Results of the interview with the students and teachers also revealed that both the students and the teachers had positive attitudes towards implementing the participatory approach and they were willing to use at least some of the tasks and activities in their future courses.
