Peer collaboration in small groups has increasingly been recognized as an instructional technique that promotes interactive skills, socialization, learning and achievement across a range of subjects and disciplines. The study aims to measure Saudi female EFL learners’ attitudes toward the effectiveness of cooperative learning (CL) and its impact on their social and academic skills. In the present study, the researchers utilized a quantitative research tool to collect data from the participants. A 25-item Likert-scale opinionnaire was designed with closed-ended statements to measure five variables laid down by Johnson et al. tabulated into five sections. The survey was administered to 100 Saudi female EFL learners at undergraduate level to measure their attitudes toward the effectiveness of CL. The findings of the study indicate that CL enhances EFL learners’ social skills, maximizes inter-group relations, mastery of the course content and academic achievement. It further develops EFL learners’ individual and group accountability, leadership qualities and decision-making power. It is assumed that EFL learners’ cognitive faculties can be activated and optimum results can be obtained if this interactive strategy is implemented in a structured pattern with a properly designed rubric focusing on the five essential components of CL.
