Abstract

Students need teachers with a deep understanding of mathematical concepts to improve their mathematical knowledge and achievement. The observation results of several elementary school teachers showed that they still have a lack of understanding of the geometry concepts. This research is an exploratory study with a qualitative approach that aims to describe the performance of elementary school teachers in understanding the concepts of triangles and squares. The participants in this study were elementary school teachers across Soe City District. A description test deals with the geometry concept of two-dimensional shapes that were implemented to determine the most appropriate teachers to participate in the study. Thirty-three teachers were then selected based on this preliminary test results. In-depth interviews were also conducted with the participants. The data analysis showed that the participants had a lack of understanding of the concept of two-dimensional shapes and necessary arithmetic skills. Moreover, the data suggested that the participants held various perceptions regarding their understanding of certain concepts based on their experience in teaching the mathematical concept. Based on these results, some programs are recommended to improve professionalism and pedagogical competencies, such as a refresher training program for basic mathematical material and training in teaching aids used. These programs are expected to help prepare elementary school teachers in teaching mathematics.

Abstract

The gap in the decline in PISA scores is likely due to an abstract and contextually irrelevant approach to teaching mathematics, which often fails to connect everyday experiences that utilize the potential of local wisdom to make learning more engaging and culturally relevant. This research aimed to develop mathematics learning materials that integrate local wisdom to improve students' mathematical literacy skills. The study employed the Research and Development (R&D) method with the ADDIE development model. The developed learning materials incorporated elements of Timor local culture, including traditional houses, handwoven fabrics, and traditional games, as contextual tools to enrich the learning experience. The quality of the developed product was evaluated for three aspects: validity, practicality, and effectiveness. The validation results showed an average score of 93.1%, which is included in the very valid category. Product implementation showed a significant increase in trial results, with all students meeting the minimum competency criteria after using the learning materials. The final score of students' responses after using this developed product is 96.93%, categorized as very practical. The average N-Gain score of 0.76 significantly increased students' mathematical literacy skills. Feedback from students highlighted that learning materials inspired by local wisdom made the learning process more engaging and relatable. Teachers appreciated the inclusion of cultural elements, noting that they facilitated a deeper connection between mathematical concepts and students' everyday experiences. The research underscores the transformative potential of a culture-based approach in mathematics education.
