Ray Diagramming Technique for Concave Mirrors Using Freeware-Based Module

Abstract

INTRODUCTION

This study aimed to create a freeware-based module for the least mastered competency in Grade 10 Science -ray diagram for concave mirrors. The self-paced module intended to advance and develop learners was implemented in a computer laboratory by utilizing offline-based web page.

METHODS

Quantitative experimental design was used in this study. Purposive sampling for 40 students were used as respondents of the study. Top 20 students represented the advanced learners and bottom 16 students represented the developing learners.

RESULTS

Based on students' evaluation, the students strongly agree that the module was an effective tool for them to learn ray diagramming techniques for concave mirrors. The designs were highly acceptable, and the module were highly related to their lessons. They found the module to be an exciting way to learn.The experimental group that used the free-ware based module performed better than the traditional group for advanced learners as computed in the t-test comparing the post-test of each group.

DISCUSSIONS

Grade 10 Science teachers can use this freeware-based module in teaching ray diagramming techniques for concave mirrors. It is easily replicable and very cost effective. This can be used in school laboratory maximizing the computers given by the Department of Education.
