The Performance in Mathematics 8 Using Geoboard in Cabasan National High School

This study determined the performance in Mathematics 8 using a geoboard in Cabasan National High School. Specifically, it answered the following questions: 1. What is the performance of the control and experimental groups in the pre-test along with illustrating triangle congruence; illustrating the SAS, ASA, and SSS congruence postulates; solving corresponding parts of congruent triangles; proving that two triangles are congruent; proving statements on triangle congruence; and applying triangle congruence to construct perpendicular lines and angle bisectors? 2. What is the performance of the control and experimental groups in the post-test? 3. Is there a significant difference in the performance of the control and experimental groups in the pre-test and post-test? 4. What are the least mastered skills in the post-test of the experimental group? and 5. What activity sheets using a geoboard may be proposed to address the least mastered skills? This study applied the quasi-experimental method to determine the effectiveness of geoboards in the performance of Mathematics 8 students. The researcher employed the pre- and post-test in the control and experimental groups. The main tool used by the researcher to gather the data is a teacher-made pre- and post-test. The performance of the students in each group was determined by computing the mean score in each skill and the corresponding performance level. To test the hypothesis if there is a significant difference in the performance of the control and experimental groups in the pre- and post-tests, a t-test for independent samples was utilized.
