The study of optics involves the understanding of complex and abstract concepts, which can be challenging for students. Collaborative learning has emerged as a powerful pedagogical tool that facilitates deeper understanding by promoting interaction, discussion, and problem-solving among peers. This article explores the application of collaborative learning methods in teaching complex concepts in optics. It discusses the theoretical framework of collaborative learning, its benefits in the context of optics education, and presents empirical evidence on its effectiveness. The findings suggest that collaborative learning not only enhances conceptual understanding but also fosters critical thinking and improves students' attitudes toward the subject.
