Cooperative learning is a student-centred approach that enhances engagement and understanding. This study investigates the effectiveness of the Buddy system, a cooperative learning strategy, in improving Year 9 students’ mathematical performance in converting between decimals, fractions, and percentages (DFP), and explores their perceptions of the system. Conducted in Brunei, where the Buddy system is relatively underexplored, the study employed a mixed-methods design using pre-and post-tests, questionnaires, and student reflection journals across three intervention cycles. Results showed an overall improvement in test scores, though a few students experienced slight score declines. Students generally viewed the Buddy system positively, citing peer guidance, emotional support, and collaborative learning as key benefits. While the findings support the system’s potential within this specific context, further research is needed to assess its applicability across subjects or educational levels. © 2025 The Author(s).
