Abstract :
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.
