One of the ways to help the learners achieve success in learning is through giving support aids made by the teachers to understand and apply learning in their daily life with the use of supplementary modular learning materials. This study aimed to investigate the efficacy of supplementary learning materials in stoichiometry and find out if there would be a significant difference in the performance of the students using the developed supplementary modular learning materials. There were thirty Grade 12- STEM students involved in the study under the control group (DepEd printed module) and experimental group (Supplementary modular learning materials) in the pre-test and post-test. T-test and matched randomization were employed to test the significant difference in the test results. The pre-test mean score results showed that there were no significant differences between the two groups that remark moving towards mastery. The post-test mean score results showed that there would be a statistically significant difference between the two groups where the experimental group had a larger mean score with remark of closely approximating mastery compared to the control group remaining in moving towards mastery. Still, both modules contributed to increase the academic performance of the students but under the supplementary modular learning materials gave a positive impact in mastering the least learned competencies of the students. This implies that supplementary modular learning materials can be utilized as instructional materials during the distance learning process as effective learning tools. Thus, the school may conduct webinars or seminars, training, programs and activities that will enhance more skills of the teachers in crafting supplementary modular learning materials.
