abstract cooperative learning refers to small groups of learners working together as a team to solve a problem, complete a task, or accomplish a common goal. in a cooperative environment one’s success is directly related to the success of other members because the focus on the individual shifts towards the group. to test the effectiveness of the method, using jigsaw technique, a study was conducted to find out how it can improve reading comprehension ability of intermediate-level students of chabahar maritime university. administering a nelson english language proficiency test (see appendix), two homogenous groups of students were selected. selecting a quasi-experimental design, two groups of 30 students based on the result of the standard proficiency test were assigned as experimental and control groups. after that, a michigan reading comprehension test was administered to ensure students’ reading comprehension ability prior to the study. the first group received instruction using jigsaw technique and the second one was taught using traditional teacher-fronted method. finally, a michigan reading comprehension test was administered as the posttest and the results were analyzed by means of spss software. conducting two independent and paired t-tests between the pre and posttest scores of both groups, the mean score of the control group on the posttest was 15.23 while that of the experimental group was 18.23. the p value was p=.000 < p= .05, it can be concluded that the experimental group has performed significantly different from the control group on the posttest. moreover, in this study, it was intended to investigate the degree of interaction of male and female subjects in their groups toward cooperative learning situation. as a conclusion, it was found that the female learners performed better in their cooperative groups than the male learners. in addition, as far as the heterogeneous groups with regard to gender, culture, and academic performance are concerned, it was found that jigsaw technique was effective for increasing reading comprehension ability of intermediate-level students of chabahar maritime university. key words: cooperative learning - jigsaw technique - reading comprehension-information gap - gender- zone of proximal development - scaffolding
