Abstract

Learning mathematics requires appropriate learning media. The facts in the field of learning are textbook and monotonous. Kartu Operasi Bilangan (KOBI) is a manipulative media developed through game-based methods Teams Games Turnament (TGT). This media is used to support the learning process of students in the classroom both individually and in groups. The purpose of this research is to determine the effectiveness of the KOBI media in enhancing students' creative thinking abilities. The study was conducted on 7th-grade students at MTsN 7 Malang, focusing on the topic of integers. The research utilized a quantitative approach through quasi-experimental methods. Data collection involved tests, questionnaires, and direct observations during the learning sessions. The research findings concluded that the KOBI media is effective in supporting the learning process to enhance students' creative thinking abilities

Abstract

This study investigates ninth-grade students’ mathematical representation abilities in solving number pattern problems, focusing on how they construct and apply visual, symbolic, and verbal forms of representation. Using a descriptive qualitative design, research subjects were selected purposively based on diagnostic test results. Data from written tests were analyzed inductively following the Miles and Huberman model. The findings indicate that students who used structured visual representations, such as paired number lists, were more successful in identifying pattern regularities and reduced cognitive load. However, symbolic representations were less consistent. Although some students were able to recall and apply the arithmetic sequence formula, errors occurred during substitution and algebraic manipulation, indicating partial conceptual understanding. Verbal explanations also emerged but were insufficient to bridge visual and symbolic reasoning. Overall, this study emphasizes the importance of learning strategies that support the integration of visual, verbal, and symbolic representations in solving number pattern problems. Therefore, teachers are advised to provide contextual problems and discussion activities that can train students to use various forms of mathematical representation in an integrated manner.
