Teaching Wave Concepts Using Self-Made Wave Machine and Computer Simulator

Abstract

This study aimed to investigate the effectiveness of utilizing a self-made wave machine and a computer simulator in teaching basic concepts of waves to Grade 7 students. Drawing on Schwab's Inquiry- based Learning Theory, the research explored how these hands-on and technology-based approaches impact student performance and interest in science education. The researcher used descriptive-correlational and comparative designs. A total of 109 students utilized the self-made wave machine, and 110 students used the computer simulator. These approaches were randomly assigned to the two groups of students. The findings revealed that the students' performances after using the self-made wave machine and computer simulator were both at the “outstanding” level. The data also indicated no significant difference in the students' performances after using the self-made wave machine and computer simulator. Furthermore, students’ interest in using the self-made wave machine and computer simulator was generally “high.” Lastly, no significant relationship was found between students’ interest in activities using self-made wave machine and computer simulator and their performance. These findings suggest that hands-on and digital methods can effectively support science learning, providing educators with versatile tools to engage students. Incorporating self-made apparatus and simulators in science education may enhance student engagement and understanding without significantly altering performance outcomes.
