Abstract
This study examined the effectiveness of a Game-Based Reinforced Learning Packet (GBRLP) in improving students' mathematical competency in Trigonometry 9. The intervention was developed to address persistent challenges in teaching abstract trigonometric concepts, such as angles of elevation and depression, as well as the laws of sines and cosines. Using a pre-experimental one-group pre-test–post-test design, the study involved 30 Grade 9 students from a public high school in Sariaya, Quezon. Instruments included a validated 40-item test and a perception survey on facilitation and content. Results showed a substantial improvement in student performance. The mean pre-test score was 8.67 (SD = 2.71), with 70% of students falling in the "Needs Improvement" category. After exposure to the GBRLP, the post-test mean rose to 29.90 (SD = 3.73), with 47% achieving "Excellent" and 53% "Proficient." The paired t-test revealed a statistically significant difference (t = -22.88, p < .001), confirming the effectiveness of the GBRLP. Students' perceptions also reflected high satisfaction, with facilitation rated at M = 4.95 and content at M = 4.80. The findings highlight that game-based learning fosters active engagement, collaboration, and retention, transforming mathematics learning into an interactive experience. The GBRLP effectively reduced math anxiety and improved problem-solving abilities, making abstract concepts more accessible. In conclusion, the study confirms that incorporating game-based instructional tools enhances both student achievement and motivation. It is recommended that similar strategies be adopted across other mathematics domains and grade levels to validate their scalability and further assess their impact.
