Abstract

The purpose of this study is to evaluate the effectiveness of using the Realistic Mathematics Education (RME) approach assisted by GeoGebra in teaching mathematics at a public junior high school in the city center. To assess the extent to which the implementation of RME meets the desired learning standards, the CIPP model (Context, Input, Process, Product) was applied. Data were collected through interviews, observations, and document analysis, and analyzed using a descriptive-evaluative method. The findings reveal that the implementation of RME assisted by GeoGebra generally meets the required criteria. The context component reached 100%, input 80%, while the process and product components achieved 85% and 100%, respectively, all of which are categorized as highly appropriate. Nevertheless, several challenges were identified, including limited internet access for using GeoGebra, the lack of professional certification among some teachers, and less-than-ideal instructional time. Overall, the RME approach assisted by GeoGebra proved effective in enhancing students’ conceptual understanding of mathematics, particularly on the topic of three-dimensional shapes such as cubes and rectangular prisms. The average score of students’ conceptual understanding increased significantly from 47.76% in the pretest to 80.29% in the posttest, with the indicator “restating a concept” showing the highest improvement at 93.27%.

Abstract

This research studied the application of Realistic Mathematics Education and GeoGebra which could enhance students’ conceptual understanding in mathematics, especially for geometry themes on flat-sided shapes. The study included 26 eighth-grade students of a junior public high school in Yogyakarta, Indonesia. The research, which adopted a pre-experimental design with one-group pretest–posttest arrangement, intended to explore the extent of students’ understanding improvement as GeoGebra was implemented in RME-based learning. Two conceptual understanding tests were applied, before and after intervention, alongside observation sheets aimed at monitoring activities in the class. The analysis showed that the average score increased from 47.76% to 80.29%. The test of the paired sample t-test showed a significant difference between the pre- and post-test means. Meanwhile, the N-gain score obtained 0.63, falls within a moderate category regarding effectiveness, while the learning implementation reached 98.33%, categorized as very good. These indicate that integrating RME with GeoGebra enhances accessibility in mathematics concepts to the learners and involves active participation. Limitations, however, include poor pre-knowledge of the students, irregular attendance, and distractions from using mobile phones, probably affecting their engagement and performance.
