Abstract

This study aims to analyze the effectiveness of using miniature kelong media in improving the learning outcomes of junior high school students on the subject of mass density. Miniature kelong is a local wisdom-based learning medium that represents the structure of traditional fishing gear in the coastal area of Bintan Regency. The study used a mixed methods approach with a quasi-experimental design involving two classes: an experimental class taught using miniature kelong media and a control class taught conventionally. Data were collected through pre-tests and post-tests, then analyzed using t-tests and normalized gain. The results showed that the average increase in learning outcomes (normalized gain) in the experimental class was much higher than in the control class. The t-test showed a significant difference between the two groups. These findings prove that the kelong miniature media is effective in improving student learning outcomes because it is able to present the abstract concept of density in a concrete, contextual, and meaningful way through a local cultural approach. The implications of this study support the integration of local wisdom in science learning to improve the quality of education in coastal areas.

Abstract

This research was motivated by the low conceptual understanding and learning outcomes of eleventh-grade students at SMA Negeri Dua Singkep, caused by teacher-centered learning and the use of conventional teaching materials. This study aimed to develop a Discovery Learning-based Student Worksheet integrated with the STEM approach and the Lastek game as an innovative learning medium, and to test its feasibility, practicality, and effectiveness in Physics learning. The research method used was Research and Development with the ADDIE model, encompassing the stages of analysis, design, development, implementation, and evaluation. The subjects were eleventh-grade students of SMA Negeri Dua Singkep in the academic year of 2024 to 2025. The results showed that the developed Student Worksheet had a very high level of validity, was easy to use in the learning process, and was effective in improving conceptual understanding and student learning outcomes. Therefore, the STEM-based Discovery Learning Student Worksheet with the Lastek game is deemed suitable for use as a teaching material to support interactive, contextual, and student-centered Physics learning.
