Utilization of Photo Glossary to Improve Level of Understanding of Grade 10 Students in Heredity (Variation and inheritance)

Abstract

INTRODUCTION

Learning science relies heavily on students' ability to understand new terms and concepts. Science is considered difficult by most of students. Partly because they find science words tough and unfamiliar. Failure to understand a term will lead to confusion and misunderstanding of ideas. This failure will have a domino effect in poor comprehension and less participation. Several researches reveal that a child learns best and assimilates knowledge far more effectively through the use of images than with oral explanation in classroom teaching. This study is conducted in order to improve students' level of understanding through complementing the picture or image to the keyword and the definition.

METHODS

This study used a non-random sampling method in selecting the Grade 10 Students of Tigao National High School in the third grading period. It also utilized a quantitative method in analyzing and reporting the gathered data using descriptive statistics in the treatment of the data, specifically Mean Percentage Score and analysis of variance (ANOVA). In testing the null hypothesis of the study, ANOVA was used to determine the significant difference between the performance of Grade 10 Students before and after the intervention.

RESULTS

The result of the study indicated that the performance of Grade 10 students has greatly improved after utilizing the photo glossary in the teaching-learning process. Based on the result, a significant difference exists between the level of understanding of Grade 10 Students before and after the intervention. The result implies how a photo or any visual aid simplify the complicated lesson and intensify the comprehension of the students.

DISCUSSIONS

The use of photo glossary which complemented the keyword, definition, and the photo was a great help as a tool in improving the comprehension, maximizing understanding, and thus improve the performance of the Grade 10 Students. As a teacher, it is important to know how pictures help in better comprehension and deeper understanding of concepts, so that one may utilize this tool for achieving desired learning outcomes.
