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.
