Sebagian besar respon peserta didik setelah penggunaan GeoGebra selama kegiatan pembelajaran adalah sangat baik. Students' mathematical creative thinking skills in Indonesia are still considered low. This is partly caused by the use of learning models and media that do not sufficiently encourage the growth of these skills; therefore, it is necessary to select innovative learning models and media that can foster mathematical creative thinking. One such approach is the use of the Creative Problem Solving (CPS) model and GeoGebra software. The purpose of this research is to determine the improvement of students' mathematical creative thinking skills through the implementation of the Creative Problem Solving (CPS) model assisted by GeoGebra compared to the CPS model assisted by PowerPoint. Furthermore, this study examines the difference in the improvement of creative thinking skills between the two groups. Regarding the use of GeoGebra, students' responses were observed after its implementation in learning activities. Based on the results of the N-gain test, t-test, and Mann-Whitney test, it can be concluded that the use of the CPS model assisted by GeoGebra can improve creative thinking skills. Moreover, the majority of students' responses toward the use of GeoGebra during learning activities were very good.

Abstract

This study aims to analyze the relationship between self-concept and adaptive mathematical reasoning ability of eighth-grade students at SMP Negeri 3 Tarogong Kidul, Garut. Adaptive reasoning ability is an important skill in facing the challenges of the 21st century, while self-concept is suspected as one of the internal factors that influence it. This study uses a quantitative approach with a non-experimental method. The research subjects were 30 students selected through a purposive sampling technique. The instruments used included a descriptive test to measure adaptive reasoning ability and a Likert scale questionnaire to assess self-concept. The normality test using Shapiro-Wilk showed that both variables were not normally distributed, so the relationship analysis was carried out using Spearman Rank correlation. The results showed a significant relationship between self-concept and students' adaptive mathematical reasoning ability, marked by a significance value of 0.000 <0.05 and a correlation coefficient of 0.624 which is included in the strong category. The coefficient of determination of 38.9% indicates that self-concept contributes to adaptive reasoning ability, while the remaining 61.1% is influenced by other factors, such as learning interest, conceptual understanding, and student creativity. Overall, this study concludes that mathematical self-concept plays an important role in improving students' adaptive reasoning ability, so strengthening the affective aspect needs to be part of the mathematics learning strategy
