Impact of Using PhET Simulation for Teaching Science Concepts to the Standard VIII Students in Pudukkottai District, Tamil Nadu, India

Abstract

Simulations represent computational replicas of actual or hypothesized scenarios or natural occurrences. These virtual models enable users to investigate the consequences of altering parameters within them. PhET Interactive Simulations, often referred to as "PhET," constitute a series of free online interactive simulations developed by the University of Colorado Boulder. These simulations are purposefully crafted to facilitate improved comprehension and learning of various scientific and mathematical concepts for both students and educators. This study endeavours to evaluate the current grasp of science concepts among eighth-grade students and aims to enhance these concepts through the utilization of PhET simulations. Five pivotal science concepts were selected from the eighth-grade science textbook in Tamilnadu as the focus of this study. The research employed a two-fold approach, consisting of an experimental group and a control group. An assessment tool comprising opinion-based questions and achievement-based tests (questionnaire) was employed. The study commenced with a pre-test for the control group, followed by a post-test after delivering suitable teaching-learning experiences to the experimental group. Based on statistical data, there was a significant difference between the control and experimental groups. It concludes that the conventional lecture-based approach in teaching science concepts proved inadequate in achieving desired learning outcomes. In addressing these shortcomings, PhET interactive simulations are shown to be engaging, effective, and valuable learning tools for diverse students and the application of innovative and interactive techniques, such as PhET simulations, notably improved learners' comprehension and academic achievement. These simulations are recommended as effective instructional aids for comprehending science concepts and enhancing the academic achievements of eighth-grade students in classroom settings
