Development and Validation of Supplementary Module in Grade Nine Algebra

Abstract

INTRODUCTION

The Philippines, like any other democratic countries all over the world, is dedicated to the task of providing its citizens with the opportunity for intellectual, social, economic, and physical development. It is important that the citizens are literate, socially responsible, useful, patriotic, righteous and law abiding. It is necessary to strengthen the Philippines' performance in Mathematics in order to maximize the contribution of the country's vast human resources in attaining the goals of industrialization and economic development.

METHODS

In this study, the researchers used the experimental method to determine the effectiveness of the developed module in Mathematics 9 while the descriptive method was used to evaluate the developed modules in terms of the identified criteria. The student respondents of the study were thirty (30) Grade 9 students from Punta NationalHigh School while the teacher expert evaluator respondents were 15. All of them are from Punta National High School in Calamba, Laguna.

RESULTS

Before using the developed modules in the Grade 9 Mathematics majority, 17 or 56.67 % of the students performed fairly satisfactory, followed by 7 or 23.33% performed unsatisfactorily, while 6 or 20.00% performed satisfactorily. After using the module, the performance in Math 9 increased as shown in the decrease in the lowest level of performance from 7 students in the pre-test down to only 2 in the post-test. There is a significant difference between the pre-test and post-test mean.

The claim was based on the increase of the mean score from 15.70 in the pre-test to the mean score of 28.93. The developed modules are high invalidity in terms of Objectives, Topics, Activities, and Evaluation. The developed modules were high in acceptability level in terms of particularly in the Language, Content, Relevance, Sequence, and Organization, but Very High in Contents and Potential Usability

DISCUSSIONS

Based on the findings and conclusions of the study, the developed Modules in Grade 9 Mathematics should be used by the Mathematics teachers. The Mathematics teachers must develop similar modules covering the learning competencies of the first, third and fourth grading periods for students' use in the future. The Mathematics department should initiate to conduct a workshop on the development of modules. The suggestions given by the expert respondents should be considered in the development of modules by the mathematics teachers.
