Abstract

This Community Service Program aims to revitalize and implement Geogram (Geometry Tangram) as an innovative learning medium to address the difficulties faced by students at SMAN 2 Tarakan in visualizing and internalizing geometry concepts. The method employed was Participatory Action Research (PAR), involving teachers and 32 students. The main stages included Needs Assessment via Focus Group Discussions (FGD), the Revitalization of Geogram (which resulted in the Geogram media and a comprehensive guide book), and the Implementation Phase utilizing hands-on, Geogram-based expeditions. The activity results demonstrated a significant impact. Quantitatively, 92% of the students reported that learning geometry became easier and more enjoyable after using Geogram. Qualitatively, the program successfully fostered a supportive and innovative learning climate. The hands-on approach proved effective in overcoming conceptual difficulties, as students showed a much better understanding of the difference between rotation and reflection following the practical sessions. The success of the program was cemented by SMAN 2 Tarakan’s formal commitment to permanently integrate Geogram into its learning media bank. This signifies the achievement of the objective for Science and Technology transfer and positions the program as a model of best practice in enhancing spatial and geometrical literacy. Geogram proved itself to be an effective instrument for bridging the gap between abstract visual representation and robust conceptual understanding.

Abstract

This article examines mathematical connection ability, an essential competency emphasized in the National Council of Teachers of Mathematics (NCTM) recommended mathematics learning objectives. Specifically, this research aims to describe students' mastery of mathematical connection ability in the topic of Quadrilaterals and Triangles. Employing a descriptive qualitative methodology, the research instrument consisted of three essay-type test questions on mathematical connection ability, which were implemented to collect data. Data analysis revealed that the average percentage of students' achievement in mathematical connection ability was 30%. These findings indicate that middle school students' mastery of the mathematical connection ability in the topics of quadrilaterals and triangles remains relatively low. The results of this study provide educators with a foundation for designing more effective learning experiences to enhance students' mathematical connection ability. The importance of developing this ability lies not only in fostering a deep conceptual understanding but also in applying mathematics in broader contexts, both within and outside the field of mathematics.
