Abstract
Mathematics teaching is a never-ending struggle to help the students become mathematically literate, and develop favorable attitudes towards mathematics. This aim had hardly attained in the history of mathematics teaching. This study was conducted to determine the effectiveness of teaching ‘factoring of polynomials’ through geometric physical models to third year high school student at San Joaquin National High School (SJNHS). True experimental method using the pretest-posttest control group research design was used in this study. The IQ test, pretest-posttest teacher made test and survey questionnaire were administered to high school mathematics teacher. Validation of pretest-posttest was constructed based on the table of specification prepared by the researcher utilizing the Bloom’s Taxonomy of objectives and was subjected for face validity among mathematics teachers. The selection of the final number of items was based on the level of difficulty of an item which had some relation with the discriminatory power of an item. In eliciting the data, two sections of the third-year students from SJNHS were utilized as the subject of the study, the experimental and control group both 40 student’s respondents. As a result, both groups demonstrated improvement in their achievement in the four lessons on factoring polynomials. This showed that there was a significant difference between the means in the pre-test and post-test in lessons on factoring polynomials in both control and experimental groups. The study showed that the geometric physical models developed were suited to any level of intellectual ability among third year students of SJNHS. Further studies in the use of geometric physical models in the areas of Geometry and Algebra should be undertaken to determine what other areas can be taught effectively through the use of geometric physical model approach.
