Abstract

The problem found is the low understanding of concepts on division operation material. This is due to the difficulty of understanding the abstract material. This is triggered by the lack of utilization of relevant learning media to overcome it. This study examines the effect of RME-based division machine props on the conceptual understanding of division among seventh-grade students at SMP Yayasan Perguruan IRA. This research design uses a pre-test and post-test control group as part of a quasi-experimental research method with a quantitative approach. The population of this study was all seventh-grade students, with a sample of 18 students in the control class and 18 in the experimental class. In the post-test, the control and experimental classes obtained sig <0.05, so it was stated that there was a significant difference between the experimental class and the control class. Thus, the study results showed a substantial effect in applying Realistic Mathematic Education (RME)-based division machine props on understanding the concept of division operations in class VII of SMP Yayasan Perguruan IRA. The findings highlight the practical effect of RME-based teaching aids in improving students' conceptual understanding and emphasize the need for scalable, inclusive teaching aids in mathematics education.

Abstract

This study focused on identifying the magnitude of the impact of a deep learning approach assisted by GeoGebra-based interactive PowerPoint media and animated videos on junior high school students’ conceptual understanding, particularly on the topic of straight-line equations. The research employed a quasi-experimental methodology with a pretest–posttest design involving two groups: the experimental group and the comparison group. The measurement instruments consisted of essay questions, and the data were analyzed using normality testing, homogeneity testing, and an independent t-test. The findings revealed a significant improvement in the experimental group’s conceptual understanding. The higher average posttest score compared to the control group confirmed that the use of interactive media enhanced students’ understanding of the material in a more visual and engaging way. Furthermore, the deep learning strategy optimized students’ active involvement in understanding and connecting relevant material to real-life situations. Thus, the synergy between digital media and this learning strategy was proven to effectively enhance conceptual understanding.
