The results showed that collaborative learning was generally high, with promotive interaction being the highest and individual accountability the lowest. There was a significant relationship between collaborative learning and academic performance, indicating that collaborative learning positively influences learners' academic outcomes. The study recommends that teachers should encourage collaborative learning to promote positive attitudes, motivation, and a sense of shared purpose.
