Abstract
Research suggests that collaborative learning may enhance the benefits to learners when solving cognitively demanding tasks. However, there are concerns about how students with different achievement and engagement levels perceive these benefits. This study examines how students with varying achievement and engagement levels respond to collaboratively solving cognitively demanding tasks. Findings reveal that collaboration enhanced peer learning and enjoyment, particularly for low and moderate achievers, and increased engagement among less engaged students. The findings highlight the potential of collaborative learning to improve problem-solving experiences for diverse learners.
