The Effectiveness of Using Powerpoint Presentation in Teaching Electromagnetic Spectrum to the Academic Performance of Selected Grade 10 Students of the Lipa City National High School

Abstract

INTRODUCTION

Man has strived for excellence in all spheres of life. This desire has given birth to new inventions and innovations in all walks of life. The world of education had been influenced by an increase in the use of technology. Technology now plays an important role in imparting knowledge to the students. Students must be provided with maximum opportunities to become functionally literate in science. This reflects that there is a need for the teachers to innovate and use all the possible resources in order to increase the competency of our learners with one innovation that is the use of computer in teaching. This action research aims to determine the effectiveness of using PowerPoint presentation in teaching a specific competency such as electromagnetic spectrum in Grade 10 Science in the Lipa City National High School

METHODS

The study was conducted at Lipa City National High School during the School Year 2016-2017. The respondents were composed of 138 Grade 10 students from 10-Diamond. 10-Sapphire, 10-Jasper and 10-Beryl. The study used the experimental method of research wherein pretest and posttest was conducted to gather the data. The control group was taught using the traditional such as the chalk-talk method while facilitating with the aid of PowerPoint presentation was given to the experimental group.

RESULTS

For the pretest results, it could be gleaned from the findings that there is no significant difference in the pre-test results between the two teaching methods. This means that students from both groups had the same understanding of the lesson before it was taught.On the other hand, the posttest results when the two groups of respondents were evaluated. It was revealed that there is a significant difference between the traditional method and multimedia presentation. This means that the experimental group where the multimedia presentation was used had significantly better retention of facts and concepts. For this reason, students were able to answer much better than the control group.

DISCUSSIONS

The study revealed that utilizing technology in teaching was effective and made a better result than employing the traditional method. Based on the findings and conclusion of the study, this recommendation was drawn Computer-aided instruction is a must for teachers for effective learning to happen.
