Penelitian ini bertujuan untuk menganalisis hambatan epistemologi siswa dalam menyelesaikan soal cerita aritmatika sosia. Indikator hambatan epistimologi dalam penelitian adalah hambatan pada pemahaman konsep, hambatan dalam menerapkan prosedur dan hambatan dalam operasional. Jenis penelitian ini menggunakan pendekatan kualitatif dengan metode Penelitian Desain Didaktik (Didactical Design Research). Penelitian ini dilakukan di SMPK Santo Yosep Kupang tahun ajaran 2021/2022. Instrumen yang digunakan dalam penelitian ini adalah soal tes uraian, wawancara dan dokumentasi pada siswa kelas VII-D SMPK Santo Yosep Kupang. Subjek dalam penelitian ini yaitu 3 siswa kelas VII-D SMPK Santo Yosep Kupang. Instrument yang digunakan dalam penelitian ini ialah soal tes uraian sebanyak tiga soal dan melakukan wawancara kepada masing-masing subjek. Wawancara dilakukan untuk mengetahui hambatan siswa dalam pemecahan masalah matematis pada materi Aritmatika sosial. Hasil analisis menunjukan bahawa adanya epistemological obstacle pada ke 3 orang siswa SMPK Santo Yosep Kupang yaitu kesalahan dalam menentukan rumus, teorema atau definisi dan juga adanya kesalahan dalam mengitung nilai serta langkah-langkah penyelesaian soal aritmatika sosial yang diperintahkan tidak sesuai. Dan hasil dari penelitian ini menunjukkan bahwa dari 3 siswa yang di analisis hanya 1 siswa yang memahami sekurang kurangnya 2 dari 3 indikator.

Literacy skills are one of the mathematical abilities that all students need to have in today's global era. However, not all students in border schools have good mathematical literacy skills. This type of research is descriptive qualitative which aims to get an overview of the mathematical literacy skills of students in border areas in solving Minimum Competency Assessment-based problems and also identify factors that influence these skills. This study involved all 57 seventh grade students in the first semester of SPMN Lorontuan Atambua - NTT. The test questions were four numbers in the form of true and false, multiple correct answers and short form. The results of the analysis found that some of them could not read fluently; not all students had a good understanding of basic mathematical concepts; lack of learning experience of contextual problems or story problems that caused them to have difficulty understanding the problem, choosing the mathematical concept used to answer the problem and could not analyze the information provided. The reconstruction that we provide is the need to build a strong mathematical understanding by designing mathematics learning that integrates local wisdom and technology and provides them with varied learning experiences on story problems. Keywords: math skills, literacy, schools at the border. DOI: http://dx.doi.org/10.23960/jpmipa/v25i2.pp728-751

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.

How to Build Mathematical Abilities in Deaf Students? A Grounded Theory. Objective: This study aims to produce a conceptual model as a strategy for building mathematical abilities in deaf students. Methods: This is qualitative research with a grounded theory design involving 45 deaf students from four middle schools in Indonesia. Findings: The results of the data analysis at the open coding stage obtained five categories of visual, feeling, understanding, learning experience, and habits in learning mathematics. At the axial coding stage, mathematical understanding was used as the core category. While at the selective coding stage, a conceptual model was built where each category contributes to building mathematical abilities. Conclusion: That efforts are crucial to develop the mathematical abilities of deaf students comprehensively. This can be done by visualizing the problems, connecting the problems with the student environment, providing learning experiences with various questions, giving motivation, and increasing self-confidence using praise and more attention from parents or teachers. Keywords: deaf student, grounded theory, mathematical abilities.DOI: http://dx.doi.org/10.23960/jpp.v12.i2.202240

Mathematics and culture are two different things, but they have a very close relationship in everyday life included in learning activities. Therefore, this research aims to describes the process and results of developing student activity sheets based on local culture on Simple Trigonometric Function Graphs. This research type is research and development. The product developed in this research is a student activity sheet based on local culture on Simple Trigonometric Function Graphics. Student activity sheets are developed based on a modified 4-D development model, which consists of defining, designing, and developing. At the definition stage; conducted a preliminary analysis, student analysis, material analysis, task analysis and specification of learning objectives. At the design stage; The preparation of student activity sheets based on local culture is carried out, selecting the format and then doing the initial design. At the development stage; The design results are validated by the expert and then revised according to the expert's notes. From the results of the research and data analysis conducted by researchers, it was found that the student activity sheets developed had met the criteria for good learning tools because they were declared valid, practical and effective.
