Abstract

Penelitian ini bertujuan untuk mengetahui efektivitas ChatGPT sebagai alat bantu mahasiswa untuk berpikir kritis dan mendeskripsikan berpikir kritis mahasiswa dalam menyelesaikan masalah aljabar dengan bantuan ChatGPT. Penelitian ini merupakan penelitian mix method dengan explanatory sequential design yaitu data dianalis analisis secara kuantitatif terlebih dahulu dan dilanjutkan dengan secara kualitatif deskriptif. Hasil penelitian ini menunjukkan rata-rata nilai berpikir kritis kelas ChatGPT (56,67) lebih besar daripada kelas kontrol (41,33). Hasil analisis uji-t menunjukkan bahwa t-hitung (2,58) > t-tabel (2,03) dan nilai p-value 0,007 yang mana lebih kecil dari 0,05. Sehingga dapat disimpulkan bahwa hipotesis awal (H0)ditolak yang artinya ChatGPT efektif untuk mendorong mahasiswa kemampuan berpikir kritis. Lebih lanjut mahasiswa yang berpikir kritisnya tergolong tinggi akan mempertanyakan kredibelitas informasi dari ChatGPT maupun masalah, membuat kesimpulan yang tepat dari informasi yang diperoleh, dan menyelesaikan masalah dengan strategi yang tepat. Sedangkan mahasiswa yang berpikir kritisnya tergolong rendah menerima informasi dari ChatGPT maupun masalah tanpa mempertanyakan kredibilitasnya, dan hanya menyalin apa yang dikerjakan oleh ChatGPT tanpa memperhatikan kebenarannya.Kata kunci: Berpikir kritis, ChatGPT, Masalah aljabar, Mahasiswa Abstract: This research aims to determine the effectiveness of ChatGPT as a tool for assisting per-service teachers in critical thinking and describe the critical thinking of students in solving algebra problems with the help of ChatGPT. This study uses a mixed-methods approach with an explanatory sequential design, where quantitative analysis is conducted first, followed by qualitative descriptive analysis. The results of this research show that the average critical thinking score for the ChatGPT class (56.67) is higher than the control class (41.33). The t-test analysis indicates that the t-value (2.58) > t-table (2.03) with a p-value of 0.007, which is smaller than 0.05. Therefore, it can be concluded that the null hypothesis (H0) is rejected, meaning that ChatGPT is effective in enhancing pre-service teachers’ critical thinking abilities. Furthermore, pre-service teachers with high levels of critical thinking tend to evaluate the credibility of information from both ChatGPT and problems, make the correct conclusions from acquired information, and solve problems using appropriate strategies. On the other hand, pre-service teachers with low levels of critical thinking tend to accept information from ChatGPT and problems without questioning their credibility, merely copying what is generated by ChatGPT without paying attention to its accuracy.

Abstract

Mathematical creative thinking is an essential skill that needs to be developed in pre-service mathematics teachers. This skill is needed for them to be able to compose or propose problems that make students think creatively as well. The purpose of this study was to investigate the impact of number sense and working memory on creative thinking of pre-service mathematics teachers when conducting problem posing activities. This research was a quantitative research through ex post facto approach. The subjects in the study were 121 Mathematics Education students at one of the Central Kalimantan Universities. This study used ordinal logistic regression data analysis techniques. The results of this study showed that the average number sense and working memory were 27.17 and 46.26 out of 100, respectively. Descriptively, the average number sense and working memory of students were very low which was far below the maximum range. Furthermore, there were 4 people in the very creative category, 10 people in the creative category, 62 people in the less creative category, and 45 people in the uncreative category. The majority of prospective teachers were in the less creative category, indicating their low creative thinking ability descriptively. Furthermore, number sense had a significant effect on the creative thinking of pre-service mathematics teachers in problem posing activities, while working memory did not show a significant effect.

Abstract

This research aims to develop 3D-based geometry learning media using the SketchUp application. The method used is the 4D development model, which includes Define, Design, Develop, and Disseminate. However, this research activity is conducted only up to the Development stage, which involves assessment and evaluation of the media by educational experts as well as a small trial with 13 students. The learning media created aims to help students understand the concepts of spatial geometry in a clearer, visual, and interactive way. Survey results indicate that the media using SketchUp is easy for students to use, which can help them better understand the shapes and structures of spatial figures. Additionally, this media is considered capable of increasing interest in learning and encouraging students to be more active in studying mathematics, especially geometry. Based on assessments from experts and student opinions, this learning media is regarded as good, interesting, and effective for aiding in learning. With a three-dimensional display, students can view spatial objects from various angles, allowing for better understanding.
