The study investigated social studies teachers and students attitudes toward Cooperative Learning Method (CLM) in Junior Secondary Schools (JSS) in Port Harcourt Local Government Area (LGA) of Rivers State, Nigeria. The quasi-experimental design was used. A total of 240 JSS II students with an average age of 12 years and 11 social studies teachers participated in the study. Two validated 10-item instruments, Students Attitude towards Cooperative Learning Method Scale (SATCLMS) and Teachers Attitude towards Cooperative Learning Method Scale (TATCLMS) were used for data collection. The test-retest method was used to determine the reliability of the instruments to obtain reliability indices of 0.78 and 0.86 for SATCLMS and TATCLMS respectively. Two research questions guided the exploration. Percentages and frequency were used to answer the research questions. The findings of the study were that both teachers and students had positive attitudes towards CLM, however, teachers had more positive attitudes toward CLM than the students. It was recommended among others that teachers of social studies should adopt the CLM in their instructions in the classroom so as to impact on the attitudes of the students.
