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.

Abstract

Buna is one of the woven motifs from Insana, East Nusa Tenggara Province that uses geometric motifs like a rhombus. Rhombus is a challenging material so students only memorize the formula without understanding the concept.  In order to overcome this problem, a weaving learning based on ethnomathematics has been proposed. The purpose of this study is to understand the impact on the learning achievement of students of the implementation of a realistic mathematical approach based on ethnomathematics. This is a quantitative study using a one-group pretest-posttest design. The population for this study is all fifth-grade students of SDN Bestobe, Insana District. Pretest and posttest results obtained are used for the analysis. The statistical test used is a paired sample t-test. The results show that the implementation of realistic mathematical learning based on ethnomathematics has a substantial influence on the learning achievement of mathematics students. These results contribute to adding empirical evidence related to the relationship between Ethnomathematics-based Realistic Mathematics Education approaches to student achievement.

Abstract

Students who have special needs also have the right to obtain an education as a provision for life, just like regular students. However, several learning tools for them are still very few. It is because some researchers always focus on standard students. Therefore, this study aims to develop visual-based mathematics teaching materials on integer arithmetic operations, one of which is deaf students. The development model used is a modified development model from the 4D model. Teaching materials that have been developed and tested on deaf class VIII students are suitable for use as a learning medium because they meet the criteria of being valid, practical, and effective. Valid because the average value of the three validators is 3.85. Furthermore, the practical standard is because the percentage of the average response score of students obtained is 80%. Finally, the effective criterion is that the average score of students trying to solve the test questions is 81. The results of this study contribute to providing alternative teaching materials for deaf students.

Abstract

The purpose of this community service activity is to improve the fastcounting ability of SMK students and the team can also increase the empowerment of partners according to the problems faced and can establish cooperation with partners. The activity took place on May 20, 2024 at SMKN 2 Belu involving 50 SMK students. This Community Service (PkM) activity starts from situation analysis, activity design, socialization, implementation, and evaluation of activities. Some things that can be concluded are that students look enthusiastic and give the impression that this activity is very helpful in solving math problems, all students are involved in answering the questions given, and this method is not boring because there are chants and games played together. This activity was only limited to addition and multiplication material, and lasted for 1 day only so that not all students fully understood the material presented, this resulted in some students not meeting the KKM.

Abstract

Algebra plays a vital role in developing students' higher-order thinking skills; however, in many junior high schools, algebra instruction remains focused on mechanical procedures rather than conceptual understanding and contextual problem solving. This approach limits students' ability to engage meaningfully with mathematical content, particularly in culturally diverse classrooms where learning materials often lack relevance to students’ lived experiences. To address this gap, this study presents the development of culturally grounded algebra learning materials using Google Slides, chosen for its accessibility, interactivity, and collaborative features, which offer distinct advantages over conventional static media. The study employed the ADDIE (Analysis, Design, Development, Implementation, Evaluation) model within a Research and Development (R&D) framework to systematically design and evaluate the learning materials. Conducted with seventh-grade students at SMP Lorotuan using a pretest-posttest design, the results revealed a significant increase in student achievement, with scores improving from 45.36 to 86.61 and an N-Gain value of 0.42, classified as moderate by Hake’s standard. Observations and survey data confirmed the materials’ practicality and strong cultural relevance, with students awarding a perfect cultural relevance score (560/560) and reporting increased appreciation for their local culture. This study concludes that integrating local wisdom into interactive algebra instruction can effectively enhance students’ mathematical understanding and cultural identity. The findings support the continued development of culturally responsive digital learning tools that address diverse student needs and promote equitable mathematics education.
