Enhancing Grade 4-Science Class Pupils' Performance in Science through Digital Light Processing Projector (DLP) Assisted Instruction: An Action Research

Abstract

INTRODUCTION

Science involves very broad concepts, knowledge, and application. Average periodic test results in Science in the Second Quarter of SY 2014-2015 and 2015-2016 show that pupils of Grade 4-Science class garnered average periodic test scores of 82.03% and 83.41%, respectively. This is below the standard level considering that they are in a Science class. This study focuses on to how to improve the pupils' performance and mastery level in Science through the use of a DLP projector. The study is also aimed to develop the retention rate by visual and actual presentation of lessons specifically the lessons that books and other reference materials cannot offer optimal understanding among pupils.

METHODS

A descriptive research method was employed in this study. Using the traditional approach and varied instructional materials, the researcher taught all the lessons in the second grading period prescribed in the K to 12 Curriculum Guide (GC). A group activity or Performance Work Approach (PWA) was also utilized. A pretest and posttest were administered to thirty-five (35) pupils from Grade 4-Science Class Curriculum to evaluate their performance. The said tests were again administered and compared after the DLP projector assisted instruction was introduced. The data gathered during the pretest and posttest using the traditional way of teaching and DLP assisted instruction were compared using t-test.

RESULTS

The study showed that there was a significant difference between the mean scores in the pretest and posttest both in traditional teaching method and using DLP assisted instruction. DLP assisted instruction is more effective in enhancing pupils' performance in Science. Based from the calculated Index of Mastery (IM), the DLP assisted instruction is higher compared to the traditional teaching method. Therefore, the former has greater impact in enhancing pupils' performance in Science. The results also revealed that there is a correlation between the mastery level and retention level. When the mastery level increases, it means that the retention level also increases.

DISCUSSIONS

Results revealed that the DLP assisted instruction showed remarkable impact in enhancing the performance of the pupils in Science through Education Technology. Thus, the researcher recommends to school authorities the use of DLP in instruction. Furthermore, it is recommended to conduct a similar study in another subject and/or in another grade level as focus of the research to ascertain further the results of this study.
