Abstract:

This study investigated the effectiveness of using the Filipino lan-guage as an auxiliary medium of instruction in teaching Physics among Grade 10 students at Mindanao State University–Maguinda-nao Integrated Laboratory Science High School. The research em-ployed an experimental pre-test and post-test design involving two groups: a control group taught through conventional English in-struction and an experimental group taught with Filipino as a sup-plementary language during lessons on problem-solving and com-putations. Data were collected using validated and reliable test in-struments and analyzed through mean scores, t-tests, and standard deviations. Findings revealed that the control group obtained a mean score of Fair, while the experimental group achieved a higher mean score of Good. Statistical analysis showed no significant dif-ference between the two groups before instruction, but a significant difference after instruction. These results indicate that incorporat-ing the Filipino language as an auxiliary medium significantly en-hances students’ comprehension and performance in Physics, par-ticularly in solving numerical and conceptual problems. The study concludes that bilingual instruction, where Filipino complements English, can serve as an effective pedagogical approach in Physics education. It aligns instruction with learners’ linguistic and cogni-tive capacities, promoting inclusivity, confidence, and academic achievement. The researchers recommend further integration of Filipino in science classrooms and a review of language policies to strengthen equitable and meaningful science learning.
