L2 Idioms Learning through Cooperative Teaching Techniques

The aim of this study was to investigate the effects of three techniques of cooperative learning (Jigsaw, Student Teams Achievement Divisions, and Group Investigation) on EFL learners‟ comprehension and production of English idioms. To this end, four classes of BA level Iranian EFL learners were selected. Each group was instructed in one of the above-mentioned cooperative techniques, and there was a comparison group, which received conventional non-cooperative treatment. Two one-way ANOVA procedures were used to analyze the data. The results showed statistically significant differences between cooperative and traditional teaching methods. All the three cooperative techniques turned out to be more effective in both comprehension and production of English idioms than individual learning. The findings can have implications for textbook designers, teachers, and learners.
