Abstract

The quality of teachers is an important factor in improving education. Qualified teachers need to have professional knowledge and the richness of teaching methods. Teaching methods are one of the factors that influences students’ participation in learning activities and influences their learning outcomes. This research aims to study the effectiveness of the implementation of a cooperative learning (CL) method to improve students’ learning outcomes in biology in Grade 8 and to understand students’ perceptions of CL. The study was based on a randomly selected sample of 22 students, consisting of two groups: the experiment group taught by the CL method and the control group taught by a traditional teaching and learning method (TM). Data was collected through a pre-test, post-test and questionnaires (using Likert scales), and the data were analyzed using Microsoft Excel, focusing on descriptive and inferential statistics. The results of the study showed that the mean score of the students who were taught by CL (M = 33.73, SD = 5.14) was higher than the mean score of those taught by TM (M = 24.82, SD = 7.14), and the p value was smaller than 0.05 (p<0.05). Therefore, the implementation of the CL method enabled students to have better learning outcomes than that of the TM method. Cooperative learning does not only increase students’ learning outcomes but also enables students to work collaboratively, have a sense of responsibility, and enjoy participating in learning, as well as feel satisfied with the CL method. Overall, CL should be applied in teaching and learning in Cambodia more widely because it helps students learn to cultivate their knowledge and skills, including the 21st-century skills.
