Abstract

The proportion has emerged as an important mathematical topic in high school because of its foundation in other mathematics topics. This study aims to identify the learning barriers of pre-service mathematics teachers (PMT) based on the material proportion and level of reasoning proportion. This study implemented Didactical Design Research (DDR) and used qualitative research methodologies within an interpretive paradigm. The research participants were 25 PMTs from a seventh-semester candidate teacher at a private college in Cianjur, Indonesia. The data collected from the test results and interviews were analyzed using procedures such as identification, clarification, reduction, and verification. We then present the findings in a narrative format. Langrall and Swafford categorized the results of written tests at the proportional-reasoning level. Based on the results, the PMT at the varied proportional level but at the nonproportional level 0 identified learning obstacles, which include ontogenetic obstacles, epistimology obstacles, and didactic obstacles. The results of this study are expected to be used as a basis for designing hypothetical learning for school mathematical research in future PMT.

Abstract

The limited ability of teachers to design interesting digital mathematics teaching materials, as well as the context that is free from local participant wisdom, also causes misconceptions and difficulties in understanding mathematical concepts in depth for students. This study aims to analyze the ability of pre-service mathematics teachers to design student worksheets using the GeoGebra application based on local wisdom in mathematics learning. This study uses a qualitative method with a descriptive analytical approach to describe the ability of the pre-service mathematics study program to design student worksheets with Geogebra software based on local wisdom in mathematics learning. Participants in this study were in the pre-service mathematics education study program in West Java. The data collection technique used documentation in the form of student digital open material designs. The digital teaching materials designed by pre-service mathematics students are worksheets with GeoGebra software based on local wisdom. The research instruments were lecturer and teacher assessment sheets to ensure the feasibility of digital teaching materials and student response questionnaires for the practicality of the results of the digital teaching material plan used by students. The results of the study can be explained by the fact that the ability of students in the mathematics education study program to create digital open materials, namely student worksheets and GeoGebra software media, is worthy of the high category as assessed by lecturers and teachers. Meanwhile, the students' response to the socialization of digital open media design by students gave a positive response with a high category. Thus, students' digital teaching materials support meaningful mathematics learning for students with technology and local wisdom.

Abstract

Geometry, particularly three-dimensional (3D) geometry, is often perceived by students as abstract and difficult, resulting in low engagement and interest. Addressing this issue, the present study aimed to design interactive learning media using GeoGebra integrated with Student Worksheets to enhance students’ interest in learning 3D geometry. The research employed a Research and Development (R&D) methodology, encompassing the stages of needs analysis, design, development, implementation, and evaluation. The participants were 30 students from a public high school in Cianjur, Indonesia, who were involved in mathematics instruction on 3D geometry topics. Data were collected through student response questionnaires assessing the usability and effectiveness of the developed media. The findings indicate that the GeoGebra-based Student Worksheet media met validity and practicality criteria, with students responding positively to its use. They reported that the interactive features of the media facilitated better conceptual visualization and significantly increased their interest in learning. Furthermore, implementation strategies—such as teacher demonstrations, collaborative group work, and guided class discussions—proved effective in mitigating the abstractness of 3D geometry. This research contributes to the growing body of literature on technology-enhanced mathematics instruction by offering a practical and engaging learning solution. The integration of GeoGebra-based Student Worksheets is therefore recommended as an effective pedagogical tool to foster students’ mathematical interest and conceptual understanding, especially in abstract topics like three-dimensional geometry.

Abstract

Ethnomathematics is important in recent decades, specifically in the production of gamelan instruments. Therefore, this research aimed to examine the intricate relationship between mathematics and cultural craftsmanship in Sundanese gamelan instruments made at Gong Factory in Bogor, West Java. Ethnographic methods were used to observe and describe the practices of gamelan craftsmen and the data collection process comprised carefully selected artists. These individuals actively acquire data by reviewing relevant material, observing, analyzing, and interviewing. Miles and Huberman's framework for data analysis included data reduction, presentation, inference, and verification. The procedures understood the delicate relationship between mathematics and culture in the investigated setting. The results showed that Gong Factory in Bogor preserved and promoted a unique musical heritage. Furthermore, the instruments were known for exceptional sound quality, serving as cultural relics and didactic tools, as well as teaching visitors about the manufacturing process. The factory preserved culture through the manufacture of gamelan instruments including gong, bonang, and saron. In this context, the craftsmanship used mathematical principles, specifically precise proportions and ratios. The instruments' visual and auditory qualities depended on geometry. The results significantly impacted mathematics education by enhancing cross-cultural connections, improving proportional reasoning and mathematical comprehension, and recognizing the wider relevance of principles. Culture, mathematics, and education were connected, showing that conserving Indonesian musical tradition benefited local and global populations.
