ABSTRACT : The study used the descriptive quantitative research method in gathering information. The scope is centered only on determining the acceptability of supplementary materials in teaching Traditional Games and Sports among Bachelor of Physical Education students. The data and information were gathered using a survey questionnaire which was composed of 40 questions answered by 30 BPEd students from the Laguna State Polytechnic University Sta Cruz Main Campus students. It specifically aimed to determine the level of acceptability in terms of content, design, adaptability, suitability, and usability, students mean performance in PEM 15, and the significant difference between the students’ mean performance in PEM 15 in terms of pre-test and post-test.The study’s overall results revealed that the supplementary material for PEM15 was perceived as very high. Specifically, the variables tested – content, design, adaptability, suitability and usability indicated that it received positive feedback from the students and can be effectively used for teaching PEM15. Also, the students’ mean performance in PEM15 in terms of Pretest was very satisfactory. As for the Post-test, the students exhibited an outstanding level. Findings show that from the very satisfactory, it became outstanding. This denotes that students learned further through the use of the supplementary material. Therefore the null hypothesis stating that “ There is no significant difference in the students’ performance in PEM 15 in terms of pre-test and post-test” is rejected which calls for the acceptance of alternative hypothesis. Hence, it is hereby recommended that the university may encourage the development of other supplementary materials that could help teachers develop effective students who would be future educators in the field of Physical Education.
