Development, Validation, and Effectiveness of Higher Order Thinking Skills-Based Multimedia Materials in Geometry

Abstract

INTRODUCTION

Developing critical thinking and problem-solving skills among students are some of the objectives of Mathematics in the education mainstream. Thus, the teachers have to find ways to realize this. In this study, the researcher aims to help students develop their higher order thinking skills through the use of the developed Higher Order Thinking Skills-Based Multimedia Material in Geometry.

METHODS

The researcher made use of the experimental method to determine the effectiveness of the developed Higher Order Thinking Skills-Based Multimedia Materials in Geometry and descriptive evaluative method to evaluate the developed instructional. The researcher made use of the purposive sampling over (56) fifty-six third year high school students since they were currently taking the subject Geometry as one of their subjects.

RESULTS

The findings revealed that the experimental group performed better in the posttest than the control group. Moreover, the findings show that there is a significant difference between the performance of the experimental and control group in Lesson 2, 3, 5, 6 and7 while it fails to reject the null hypothesis in Lesson 1 and4.

DISCUSSIONS

The results of the study demonstrate that the developed Higher Order Thinking Skills-Based Multimedia Materials in Geometry is an effective tool in developing the higher order thinking skills of the students in the study of Geometry.
