Abstract

This study mapped the contemporary research landscape surrounding “oral traditions as a fount of ethnomathematics knowledge” through a bibliometric analysis employed as a methodological procedure. The main problem addressed in this study is the lack of a comprehensive consideration of evolving research trends and intellectual structure within ethnomathematics, i.e., the role of oral traditions as a source of knowledge. Oral traditions, defined as the cultural knowledge, art, ideas, and practices transmitted verbally across generations, offer a rich repository of ethnomathematical insights. 713 publications were identified from the Dimensions database between 2014 and 2024. This bibliometric analysis focused on identifying key research themes, authors, publishers, keywords, or key terms distributions within the corpus of extracted publications, as well as temporal trends in publication activity and citation patterns. The findings revealed a growing interest in the field, focusing on (a) educational context, (b) cultural studies, and (c) the intersection of mathematics and language. The analysis also identified key research themes, such as (a) the role of language and culture in shaping mathematical thought, (b) the development of ethnomathematical practices, and (c) the pedagogical implications of incorporating ethnomathematics into formal education. Additionally, 11 influential scholars who are driving the field forward were identified. According to the term distribution analysis, of the 6,092 terms, 316 met the threshold (minimum number of occurrences of the term: 6). For each 316 terms, a relevance score has been calculated. Based on this score, the most relevant terms have been selected. The VOSviewer’s default setting (60% of the most relevant terms) resulted in selecting 190 terms. Based on the given criteria, there is a result of 5 distinctive clusters related to the query that emerged. This study provides theoretical insights into the conceptual foundations of ethnomathematics derived from oral traditions and empirical evidence for informing future research directions and pedagogical practices in mathematics education.

Abstract

As the Indonesian National Curriculum (INC), the Merdeka curriculum was implemented in response to students' difficulties in comprehending and utilizing basic mathematics, contributing to low numeracy skills. This study investigated mathematics teachers' perceptions in Indonesia concerning the effectiveness of INC and the supporting programs, such as the National Assessment (NA) and Pancasila Student Profile (PSP), in improving students' numeracy skills. It also aimed to identify mathematics teachers' challenges in integrating numeracy skills into the curriculum and these programs. A mixed-method study with a sequential explanatory design was used to achieve this objective. The data collection was carried out through quantitative and qualitative approaches. Closed questionnaires were explicitly used for quantitative data, while open questionnaires and interviews were used for qualitative data. Inferential statistics were used to analyze the quantitative data and a thematic analysis for qualitative data. The quantitative results showed that most teachers positively perceived the effectiveness of INC and the programs in empowering students' numeracy skills. The implementation of INC and PSP significantly influenced the empowerment of numeracy skills. The qualitative analysis provided an in-depth exploration of teachers' perceptions and the challenges faced in promoting numeracy skills in implementing INC and the programs.

Abstract

Students' performance in understanding and developing algorithms from numerical methods is crucial because these concepts require them to engage in reasoning. DL-CA facilitates learning for fifth-semester bachelor students, specifically those in mathematics education, in comprehending numerical methods, algorithm concepts, and program development. Computer-assisted learning is appropriate for internalizing discovery learning and supporting autonomous study. The condition that differentiates individual learners is the level of self-regulated learning (SRL), which significantly enhances reasoning abilities by enabling goal setting, progress monitoring, and strategy adaptation, resulting in improved critical analysis and problem-solving skills. This grounded theory research investigates the reasoning outcomes of students in learning algorithm concepts for non-linear equation problems using computer-assisted discovery learning (DL-CA) through a web platform. It examines levels of self-regulated learning (SRL) and explores students' reasoning perspectives to describe differences in each level of SRL. Data analysis involved open coding through to categorization as essential steps in grounded theory, supported by method triangulation to enhance the validity and reliability of the findings. It was conducted using HyperRESEARCH output, a tool that aids in following comprehensive qualitative research procedures. The output suggests the following conjecture: The reasoning abilities of students in the high self-regulated learning (SRL) group encompass four categories: memorization, algorithm, plausibility, and mathematical foundation. In contrast, students in the medium and low SRL groups only demonstrate imitative reasoning abilities. Novel reasoning abilities are not sufficiently explained by these students, potentially due to limitations in the instruments or misunderstandings of the problems.

Abstract

Mathematics is essential for individuals to solve everyday life problems. However, students remain insufficiently motivated in mathematics learning, necessitating the implementation of engaging teaching approaches integrated with other disciplines, such as STEAM (Science, Technology, Engineering, Art, and Mathematics). This study investigated the effectiveness of a STEAM-based Project-Based Learning (PjBL) approach on mathematical literacy and character development among secondary school students. Utilizing a mixed-methods convergent parallel design, the research employed quantitative and qualitative techniques. The quantitative data collection used a literacy skills test to measure mathematical literacy. Meanwhile, the qualitative data collection to measure students' character utilized surveys, interviews, and observations. Quantitative data analysis was conducted using the Kruskal-Wallis test, while qualitative data analysis employed triangulation, including data reduction, data presentation, and data verification stages. The study results revealed that students' mathematical literacy significantly improved after participating in STEAM-PjBL-based learning. Additionally, STEAM-PjBL fosters the development of students' character traits, including teamwork, communication, and responsibility, highlighting its potential to support holistic educational outcomes. These findings indicate that integrating STEAM principles with PjBL enhances academic performance and cultivates critical 21st-century skills.

Abstract

Geometry learning requires a comprehensive understanding of spatial reasoning, but students face difficulty in mastering the skill. As a virtual technology, Augmented Reality (AR) offers a solution to overcome the challenges in spatial reasoning with the potential to represent and manipulate objects and develop spatial images mentally. Therefore, this research aimed to develop a mobile educational game named GEMBI AR to support students' spatial reasoning skills in geometry learning. The ADDIE model consists of analysis, design, development, implementation, and evaluation phases used to conduct research and development (R&D). The participants included six expert validators, two mathematics teachers, and eighteen eighth graders. In addition, the expert validators validated GEMBI AR in terms of quality. The result showed that GEMBI AR was valid as a geometry learning tool. According to the feedback of teachers and students, GEMBI AR was practical for educational purposes since the application positively impacted spatial reasoning. Students' spatial reasoning skills were also enhanced to compare the differences in the pre-test and post-test using Wilcoxon (Z = –3.578, p = 0.000 < 0.05). Meanwhile, the N-Gain score of 0.576, showing moderate improvement, reflected gains in spatial perception, mental rotation, and visualization. These findings suggest that GEMBI AR is a functional and valid educational resource useful for helping students develop geometric spatial reasoning. Thus, geometry learning supported by GEMBI AR has the potential to enhance spatial reasoning in secondary school.

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

This study aims to understand how pre-service mathematics teachers conduct prospective analyses comprehensively. A qualitative research method with a case study design was used. The participant was Mrs N, a pre-service mathematics teacher who conducted research using DDR methodology in a grade 9 junior high school in Sindang, Majalengka, involving 48 students. Data were collected by analyzing empirical evidence from Mrs. N's prospective analysis process by uncovering the various stages of a prospective analysis. An iterative approach was used to analyze the data by refining the research questions through discussions and regular meetings with Mrs. N. The process ensured adaptability to new insights and understandings from the empirical data. Our findings reveal that the teacher draws upon fundamental philosophical principles from didactical design research, including hermeneutics, phenomenology, and ethnomethodology. By embracing these approaches, the teacher gains valuable insights into conducting research within an interpretive paradigm, allowing for a deeper exploration of the meaning of concepts, the purpose of learning, and the cultural influences that shape the educational process. Additionally, our study sheds light on the emergence of transpositional didactics theory as the prospective teacher delves into understanding the meaning of the geometrics transformation concept.
