The study was divided into three parts. The first part dealt with an analysis of the existing practice of teaching of social studies. The second part focused on the introducing cooperative learning in the social studies classroom. The third part has related to identifying the potential constrains that affected the implementation of cooperative learning. An effort was also made to identify possibilities and constrains related to the implementation of cooperative learning in the government school. The findings of study suggest that the teachers found cooperative learning helpful in developing students' higher order thinking and social skills.
