Flip Card Drill to Improve the Mastery Level of Grade 7 Archimedes Students of Agsam Integrated School in Adding and Subtracting Rational Numbers

Abstract

INTRODUCTION

The Philippine educational system is designed to provide learners with adequate time for mastery of concepts and skills that will enable them to achieve the standards they are capable of. In mathematics, learners need to learn one basic skill at a time and-at their own pace-up to their potential until they have it mastered. Conceptual understanding and applied knowledge build upon each other. Due to mathematics building upon itself, with each new mastered domain opening the door for a developmental understanding of another, students cannot afford to grasp concepts at levels beyond their current understanding. To address the issue, the researcher designed an intervention activity to improve the mastery level of these students in adding and subtracting rational numbers.

METHODS

Descriptive method was used in this research. Analysis as to who were the respondents to be selected was done based on the result of the pre-test conducted. Twenty-one student was identified. Two (2) sources of data were used: the number of correct answers of the identified students during the pre-test and the number of correct answers of the identified students during the post-test to generate possible target respondents for the intervention and level of mastery of the competency through their weighted mean.

RESULTS

After giving the pre-test, 48% were identified as possible respondents because they scored below 75% of the passing score. According to the survey answered by these students, it was found out that the main cause of low mastery level was lack of enrichment activities. They also identified some factors such as lack of conceptual and procedural knowledge, poor retention, and unavailability of learning materials. After the intervention activity provided by the researcher, results showed that there was a significant increase in the average pre-test and post-test scores of these students. Based on the findings, there was an improvement in the students' ability to perform addition and subtraction of rational numbers. They were able to master the concepts and skills necessary in performing addition and subtraction of rational numbers through the enrichment activity given to them.

DISCUSSIONS

The results show that through repeated action and practice learners may master basic concepts and skills that are prerequisite to learning complex mathematical concepts and skills. Students benefit from drills and practice because it deepens their understanding and increases familiarity with concepts.
