Abstract

This study aimed to examine the effect of the Teams Game Tournament (TGT) learning model assisted by Question Cards on senior high school students’ conceptual understanding of sound wave material. The research employed a quantitative approach with a quasi-experimental design using the nonequivalent control group design. The subjects were eleventh-grade students of SMAN 2 Lubuk Pakam, with class XI-C as the experimental group (36 students) and class XI-A as the control group (34 students). The research instruments consisted of pretest and posttest questions as well as observation sheets. The results showed a significant improvement in students’ conceptual understanding after the implementation of the TGT model assisted by Question Cards. Based on the hypothesis testing using an independent samples t-test, the posttest significance value was 0.000 < 0.05, indicating a significant difference between the experimental and control groups. The N-Gain analysis revealed that the experimental group achieved an average N-gain score of 0.65 (moderate to high category), while the control group obtained 0.31 (low to moderate category). These findings indicate that the TGT model assisted by Question Cards is more effective in improving conceptual understanding than the lecture method. In conclusion, the use of the TGT model assisted by Question Cards has a positive and significant effect on enhancing students’ understanding of physics concepts. This model is able to create an active, enjoyable, and competitive learning environment while simultaneously increasing students’ participation and self-confidence in understanding the material.

Abstract

This study aims to develop a big book learning media based on local folklore with the help of the Canva application, and to evaluate student responses and its feasibility. This big book is based on local legends, uses Indonesian, and presents relevant images to attract students' interest in learning. The research method used is Research and Development (R&D) with the ADDIE model, but only three stages are applied: Analysis, Design, and Development. At the analysis stage, pre-research was conducted at the UPTD SPF SDN Cibubukan, where interviews with grade I teachers revealed that learning Indonesian was less interesting for students. At the design stage, the researcher designed a big book using Canva, and at the development stage, the big book media was validated by material experts, media experts, and teachers. The validation results showed a feasibility score of 95% from material experts, 94% from media experts, and 95% from teachers, all of whom concluded that this media was very suitable for use in learning. The big book media developed can be applied as an initial step in the teaching and learning process, indicating that this folklore-based big book is very suitable for use in learning Indonesian.
