Abstract

Mathematics is an abstract subject so it is considered a difficult subject for some students and students. Language is a human communication tool. The use of language that is well structured and precise will make it easier for the interlocutor to understand what is being conveyed, this also applies in learning. The level of students' understanding of the material presented by educators is the main factor that can affect student learning outcomes. The method used in this research is bibliometric analysis method. Bibliometric analysis is a research method used by researchers to find the widest possible information related to keywords in the research to be carried out. The objectives of this research are, among others: (1) To find out trends regarding language research in mathematics learning communication. (2) To find out the great opportunities for further research on the topic of language in mathematics learning communication. The researcher found that there have been many studies with the keyword “mathematics”, but there is still little research related to mathematics learning, mathematics outcomes and quality. This can be an opportunity for further research to conduct research on these three keywords.

Abstract

Ethnomathematics integrates cultural elements into mathematics learning, fostering students' conceptual understanding while preserving cultural heritage. Ethnomathematics in religious architecture offers a unique perspective on the relationship between mathematical concepts and cultural values. This study aims to explore the ethnomathematical aspects of the Al-Barkah Great Mosque in Bekasi by analyzing its symbolic and geometric elements. A qualitative research approach with a realist ethnographic method was employed, incorporating interviews, observations, documentation, and literature reviews to examine the mathematical structures embedded in the mosque’s architectural design. The findings reveal that the Al-Barkah Great Mosque exhibits various geometric shapes and transformation elements, including reflection, rotation, and translation, which hold both cultural and spiritual significance. These mathematical features serve as concrete representations that enhance students' comprehension of geometric concepts. The study concludes that integrating ethnomathematics into geometry learning provides an engaging and meaningful context for students, connecting mathematical theories with real-world cultural artifacts. The implications of this study include enriching geometry instruction through cultural perspectives and providing educators with culturally relevant resources to enhance student learning and appreciation of mathematical concepts.

Abstract

Analyzing the efficiency of using flashcard media on students' thinking skills related to the topic of polygons using the Problem-Based Learning (PBL) model in class IV SDIT Global Insan Madani. The basis of this study began with the low learning achievement of students in mathematics, especially in geometry material, due to monotonous teaching methods and minimal variation in learning media. The method applied in this study is the One Group Pretest-Posttest Design, involving 24 students as samples. The findings of the study indicate that the use of flashcard media in mathematics learning with the PBL approach can significantly improve students' cognitive abilities. Flashcards play a role in visualizing concepts and facilitating understanding of the material, while PBL increases students' active participation in solving problems. The combination of these two methods has proven effective in deepening understanding of the concept of polygons and increasing students' learning motivation. This study recommends the use of flashcard media as an innovation in teaching to improve mathematics learning outcomes at the elementary school level.

Abstract

The purpose of this research is to explore the concept of school mathematics in the museum's geometry building to fill the lack of learning resources so that it can be used as a reference for learning. The method in this study uses an ethnographic approach. Data were obtained through thematic analysis, this analysis, and narrative analysis. The results of the study obtained mathematical concepts, namely spatial shapes such as blocks and cone then there are geometric transformations such as translation, reflection, and rotation, the concept of flat shapes such as circle, square and, rectangle. In conclusion, the exploration of the Gedung Juang 45 museum in Bekasi Regency can be a medium for ethnomathematics-based mathematics learning that is contextual and interesting, in line with the three elements of deep learning, namely awareness, meaningful, and fun.   Keywords: Ethnomathematics, Gedung Juang 45, Museum

Abstract

Preschool education is important for developing children’s social and cognitive skills, with early mathematical ability being a strong predictor of future success. This study evaluated the psychometric properties of the Preschool Home Mathematics Questionnaire (PHMQ) using Rasch Model Analysis. A total of 95 parents and guardians of preschool-aged children participated in the study. A total of 37 Likert-scale items were analysed. The results showed excellent person reliability (0.93) and item reliability (0.96), indicating strong consistency and well-targeted item difficulty. Of the 37 items, 32 were valid according to the Rasch fit criteria, while five items (Q13, Q15, Q22, Q24, and Q26) showed misfit based on the Outfit mean square (MNSQ), Z-standard (ZSTD), and PTMEA-CORR. The Likert scale functioned well with ordered thresholds and smooth transitions between categories. The unidimensionality test confirmed that the PHMQ measures a single construct, with 44.1% of the variance explained and only 12.8% unexplained in the first contrast. While the PHMQ shows good validity and reliability, this study focused only on basic Rasch validation. Future research should explore differential item functioning (DIF), item bias, and long-term stability to further improve this instrument and support its use in different settings.

Abstract

Ethnomathematics is an interesting learning resource because it connects the surrounding culture with mathematical concepts. This research focuses on exploring ethnomathematics in one of the games from DKI Jakarta, namely the game of umpet batu. The ethnographic approach is used to reveal the mathematical concepts in the game of umpet batu with data collection techniques through observation, interviews, and documentation, then further discussion related to mathematical concepts with mathematics teachers who know the game of umpet batu. The results showed that the game of umpet batu has simple mathematical concepts, namely basic arithmetic, probability, and flat geometry at the elementary and junior high school levels in different phases. The existence of learning resources with traditional games can help students understand math concepts in a real form and can preserve the traditional game itself.

Abstract

21st century skills should ideally be able to provide a foundation to today's learning. The purpose of this study intends to investigate the use of whiteboard fox in mathematics learning that accommodates 21st century skills. Qualitative research methods with case study types are used to uncover 21st century skills in mathematics learning using whiteboard fox. The research site is located in one of the North Jakarta State High Schools. Purposive sampling techniques were used to answer research questions in which out of 31 students 10 students were selected who were assumed to be able to provide saturated information as well as a primary data source. Data collection techniques use structured interviews with reference to 21st century skill indicators in the context of the use of whiteboard fox in mathematics learning. Data were analyzed using the 2022 version of MAXQDA through coding, sub-coding, in-vivo and MAXMaps visualization processes. The results showed various aspects that emerged in mathematics learning using whiteboard fox related to 21st century skills. Keywords: whiteboard fox, 21st century skills, math learning. DOI: http://dx.doi.org/10.23960/jpmipa/v23i4.pp1644-1664
