The present study was an attempt to identify the effect of using a modern teaching technique, i.e. cooperative learning, in a changing system of educational policy on students' and parents' perceptions towards learning. So, 71 male students studying at seventh grade in four high schools were randomly selected to participate in the study. The students' parents (N=71) were asked to participate in the study to get their opinion on the matter as well. Using the cultural dimensions of learning framework, first the cultural aspects of students' perception towards learning were identified within eight categories. Then, the effect of cooperative learning on these dimensions was examined. Finally, the areas of changes were closely explored using open-ended questions. The results of the study revealed that some previously reported cultural features were evolving among students. The results also showed the effectiveness of cooperative learning in making significant shifts in cultural perceptions of the students. These results can be applicable for all those who are involved in the language teaching and learning process.
