Abstract

This study aims to examine the effectiveness of deep learning assisted by GeoGebra on students’ critical thinking skills in the topic of Three-Dimensional Geometry (Polyhedrons) among eighth-grade students at SMPN 3 Lingsar. This research employed a quasi-experimental design with a Pretest-Posttest Control Group Design. The sample consisted of two classes: the experimental class, which received deep learning assisted by GeoGebra, and the control class, which received conventional instruction. The research instrument was an essay test measuring five indicators of critical thinking: interpretation, analysis, evaluation, inference, and conclusion. Data were analyzed using an independent t-test with SPSS version 25. The results revealed a significant difference in critical thinking skills between the experimental and control classes, with a significance value of Sig. (p) = 0.000 < 0.05. This finding indicates that deep learning assisted by GeoGebra is more effective than conventional learning. In addition to improving learning outcomes, this approach promotes active engagement, motivation, and students’ reflective abilities. Therefore, GeoGebra has proven to be a powerful tool to enhance 21st-century learning implementation, emphasizing the development of critical, independent, and creative thinking in understanding mathematical concepts more deeply.

Abstract

This study was conducted in response to the low level of students' critical thinking skills and the predominance of teacher-centered instruction in mathematics classrooms. It aims to analyze the differences in students' critical thinking skills between those taught using the MHM approach assisted by GeoGebra and those taught through traditional methods on the topic of the Pythagorean Theorem in Class VIII at SMPN 3 Lingsar, West Lombok.  This study employed a quasi-experimental design, specifically a nonequivalent control group design, involving two groups of 27 students each.  The experimental group received instruction using the MHM approach with GeoGebra, which emphasizes reflective, persistent, and evidence-based mathematical thinking habits, while the control group used conventional methods  Data were collected through pretest and posttest critical thinking assessments, student worksheets, and learning observations. The initial abilities of both groups were comparable, as indicated by the independent t-test on the pretest (p > 0.05). Posttest results showed a significant improvement in the experimental group (mean = 82) compared to the control group (mean = 65), with a posttest p-value of 0.000 (< 0.05) and a very large effect size (Cohen’s d = 1.90), indicating a substantial difference in learning outcomes between the groups.  Observations also revealed very high engagement levels in the experimental group. These findings demonstrate that the MHM approach, aided by GeoGebra, effectively enhances students' critical thinking skills and fosters reflective, systematic, and collaborative learning habits. This study recommends adopting MHM strategies and visual technologies like GeoGebra in mathematics education.
