ABSTRACT
The purpose of the study is to determine the effect of the trigonometry workbook on the learning process of the Grade 9 Special Program for Sports students of Governor Felicisimo T. San Luis Integrated Senior High School. The study used a quasi-experimental design in comparing two variables, the pretest and posttest. Non-equivalent group design using purposive sampling technique will be employed in groups, homogeneous in nature, in Grade 9 that the researcher is teaching which are involved in the research. The students will use the validated trigonometry workbook devised by the researcher for eight weeks. Based on the summary of findings, it shows that Trigonometry workbook has significant effect on the learning of the Grade 9 Special Program for Sports students of Gov. Felicisimo T. San Luis Integrated Senior High School.
On the basis of the foregoing findings and conclusion of the study, the following recommendations are offered: (1) It is recommended that DepEd Officials and school administrators should put in their school improvement plan ways in constructing and utilizing different instructional materials for the different learning areas based on the pretest and postest for each subject. (2) It is also recommended that Mathematics Teacher should further promote a mastery in a specific subject by developing instructional materials for the benefit of the teachers and students. (3) To future researchers, do further study involving two types of groups, maybe one experimental, one control group and in a different level of students to further see if there is really a significant effect.
