Development and Validation of Strategic Intervention Material on Least-learned Competency in Grade 8 Mathematics

Abstract

INTRODUCTION

This study involved the development and validation of strategic Intervention Material based on a least-learned competency in Grade 8 Mathematics. The study is conducted to five secondary schools in the Municipality of Bulan namely: Bulan NHS, Alcoba NHS, Gate NHS, J.P. Laurel HS, and San Francisco NHS. This study had 197 respondents during the conduct of pretest and185 respondents for the validation of the developed strategic intervention material.

METHODS

The study employed the descriptive correlation method. The data were tabulated, checked, analyzed, and interpreted using the frequency count, weighted mean, and Likert scale.

RESULTS

The average result of the five high schools in the Municipality ofBulanhas a performance level of30.584 during the pre-test and55.016 during the post-test, which has a low satisfactory rating for Grade 8 Mathematics on manipulating rational expressions and rational equations using the traditional method of teaching. The competency, solving a rational equation, is the least learned competency. The developed strategic intervention material was entitled "Mathworm Adventures Presents Rational Fairytales: Equating Rationally at Wonderland.” The performance of the student's increases after utilizing the SIM.

DISCUSSIONS

Based from the findings, it was concluded that the performance level of the students in five schools on rational expressions and rational equations does not meet the standard set by the Department ofEducation of75%, and this is alarming on the part of educators.
