ABSTRACT
This study employed a pre-experimental one-group pre-test–post-test design to evaluate the effectiveness of the Ray Tracing Board (RTB) as an instructional tool in improving the academic performance of Grade 10 students in predicting the qualitative characteristics of images formed by mirrors and lenses. Various statistical tools, including mean, standard deviation, paired t-test, independent samples t-test, Pearson’s r, and Cohen’s d, were used for data analysis. Results revealed a significant improvement in students’ post-test scores, demonstrating a very satisfactory performance level. The intervention using the Ray Tracing Board significantly enhanced learners' mastery of the least mastered competency in this topic. The improvement was evident in the mean score differences between the pre-test and post-test, with a t-value of 14.45. Furthermore, a large effect size (Cohen’s d = 2.70) indicated the strong impact of the RTB intervention. These findings suggest that the RTB is an effective teaching tool and should be integrated into the Grade 10 Science curriculum. Future studies are recommended to explore its applicability across different science disciplines.
