Abstract

This study is motivated by students' low critical thinking skills, particularly in three-dimensional geometry. Moreover, the limited availability of effective interactive learning media impedes the development of these skills. Three-dimensional geometry requires a more engaging and interactive approach to enhance understanding. This study aims to develop GeoGebra-based learning media within the Problem-Based Learning model to enhance students' critical thinking skills in mathematics. The research method employed is Research and Development using the ADDIE design model. The study subjects consist of eighth-grade students. The research instruments include validation sheets, practicality questionnaires, and tests. The validation results indicate that the GeoGebra validation score is reaching 95.16% (highly valid). The practicality test showed an average score of 96.09% (highly practical). The obtained N-Gain score of 0.7655 (high category) indicates an improvement in students' critical thinking abilities. The findings of this study conclude that the use of GeoGebra in PBL-based learning is effective in enhancing students' mathematical critical thinking skills and can serve as an innovative alternative for teaching three-dimensional geometry. The findings of this study have positive implications for enhancing students' critical thinking skills through the integration of interactive learning tools such as GeoGebra, which can improve engagement and understanding in mathematics.

Abstract

This research aims to improve self-regulated learning and mathematics learning outcomes for class VIII students at SMPN 4 Jonggat by applying the inquiry learning model. This research was conducted in two cycles, with research subjects in cycle I being 20 students and in cycle II being 17 students out of a total of 22 students. The application of the inquiry learning model to Circle material in class VIII shows an increase in self-regulation or learning independence and student learning outcomes. The research results showed an increase from cycle I to cycle II, where the average self-regulated or independent learning of students in cycle I was 51.75 in the medium category, increasing to 76.24 in the good category in cycle II. In addition, the evaluation test results showed an average increase from 65.75 in cycle I to 87.95 in cycle II. Thus, the application of the inquiry learning model in the mathematics subject Circle material is effective in improving self-regulation or learning independence and the learning outcomes of class VIII students at SMPN 4 Jonggat.
