Abstract

The wedding process in Sidareja village, Sidareja District, Cilacap Regency is carried out using a unique and rich traditional ceremony with a meaning that is still thick with Javanese customs. However, this culture is still not widely used to strengthen learning, especially in mathematics learning, so by using ethnomathematical studies, it is hoped that it can clarify the study of the traditional culture of marriage in Sidareja village to be used in learning at school. The purpose of this study is to explore mathematical objects contained in wedding customs in Sidareja Village, Cilacap Regency, Central Java Province. The method used in this study is a descriptive qualitative method. The data collection technique in this study uses documentation, interviews, and observations. This research was carried out by exploring the sources of activities around traditional wedding ceremonies in Sidareja starting from: Preparation, Premarital Ceremony to Panggih Ceremony. The mathematical aspects that are explored include how Preparation (determining the wedding day) is included in the measurement material starting from counting in the concept of division, addition, and numbering. In addition, it was also presented a study of learning about flat figures, namely with the form of flat shapes such as rectangles, parallelograms, triangles, in terms of many, and rhombus found in majang tarub, sindur cloth, chitak, paes, keris-kerisan, kuluk, and suweng which are used in traditional wedding ceremonies in Sidareja village, Cilacap Regency, Central Java Province

Abstract

Critical thinking skills in mathematics are among the essential competencies that need to be developed in junior high school mathematics education. However, assessment practices in mathematics learning still tend to emphasize final outcomes through written examinations, resulting in limited evaluation of students' thinking processes. This study aims to describe the implementation of portfolio assessment and performance assessment in evaluating students' mathematical critical thinking skills at SMP Negeri 4 Banyumas. The study employed a qualitative approach using a descriptive research method. Data were collected through interviews with mathematics teachers and documentation of students' work. Data analysis was conducted descriptively through the stages of data reduction, data display, and conclusion drawing. The findings revealed that performance assessment was implemented through group presentations, classroom problem-solving activities, and final quizzes, while portfolio assessment was conducted through individual assignments and students' work collected throughout the learning process. Both assessment types provided more comprehensive insights into students' mathematical critical thinking skills compared to traditional assessment methods. The study indicates that authentic assessment can support teachers in evaluating students' thinking processes, engagement, and mathematical communication skills more thoroughly.

Abstract

This study aims to critically examine the relationship between mathematics and tawhid (Islamic monotheism) and to explore how fundamental mathematical concepts can serve as a means of internalizing aqidah within the framework of Islamic education. This research employs a qualitative descriptive approach through a systematic literature review. Data sources consist of relevant journal articles, academic books, and conference proceedings published within the last ten years that discuss the integration of mathematics, Islamic values, and tawhid. The collected literature was analyzed thematically to identify patterns, concepts, and theoretical perspectives regarding the relationship between mathematical structures and monotheistic principles. The findings indicate that mathematical concepts such as numbers, patterns, logical consistency, order, and symmetry reflect the principles of divine unity, harmony, and precision inherent in tawhid. These concepts can be interpreted as manifestations of Allah’s order (sunnatullah), thereby positioning mathematics as not merely a computational tool but also a medium for strengthening students’ spiritual awareness and religious character, including honesty, discipline, and accuracy.

Abstract

This research aims to examine the relationship between mathematical concepts contained in the verses of the Qur’an and their relevance to the development of holistic and contextual mathematics learning. The method used is a literature study by reviewing Qur’anic verses that include concepts of numbers and mathematical operations, as well as related scholarly works. Data were collected through the identification and classification of Qur’anic verses containing mathematical concepts along with supporting literature. The results show that integrating mathematical principles related to numbers with Qur’anic values in the learning process can deepen students’ understanding of number concepts in a more comprehensive and contextual manner. This article is expected to contribute to the development of a mathematics education model that incorporates Qur’anic values, enabling learning that not only strengthens cognitive understanding of mathematical concepts but also builds students’ character grounded in spiritual values.

Abstract

Fuzzy thinking means the thinking process with confusion between understanding and not understanding. This research was conducted to find out the students' experiences of fuzzy thinking in mathematics communication in SMP Negeri 2 Banyumas. This was a descriptive qualitative research and the subjects were taken from the students of class 8 C using snowball technique and T.O.L (Think Out Loud) that fulfilled the criteria of fuzzy thinking either the correct one or the incorrect one. From the results, there were 2 students with correct fuzzy thinking and 4 students with incorrect fuzzy thinking. The data were collected using tests, interviews, and documentation then analyzed using Miles and Huberman model consisting of data reduction, data display, and conclusion. The results showed that: 1) the thinking process of the respondents with incorrect fuzzy thinking experienced a change. At first they were able to think correctly, but after the reflection, they were not able to explain correctly, so the answers did not reflect their understanding absolutely; 2)the thinking process of the respondents with correct fuzzy thinking experienced a change. At first they were not able to do the test correctly, but after the reflection, they were able to finish it correctly.

Abstract

This study aims to analyze the problems of digital literacy among mathematics teachers in implementing the Merdeka Curriculum in secondary schools. The research employed a qualitative approach with a case study design involving five mathematics teachers in Cilacap Regency selected through purposive sampling. Data were collected using semi-structured questionnaires consisting of Likert-scale items and open-ended questions, and analyzed through descriptive qualitative and thematic analysis techniques. The findings indicate that teachers' digital literacy is generally at a good level, with the highest scores recorded for digital device usage (M = 4.8; very good category) and digital ethics (M = 5.0), yet a significant gap was identified in technical troubleshooting competence (M = 3.4; fair category). More critically, teachers' proficiency in mathematics-specific software including GeoGebra for geometry concept visualization and function exploration, and Desmos for interactive mathematical representation reached only an average score of 4.0, the lowest dimension among all measured application competencies. This finding indicates that technology integration in mathematics learning has not been optimally leveraged, particularly in supporting students' understanding of abstract mathematical concepts through interactive tools. Furthermore, teachers continue to face several challenges, including limited infrastructure and digital devices, difficulties in integrating technology with mathematical concepts, and time constraints due to high workloads. The implementation of differentiated learning within the Merdeka Curriculum also remains a significant challenge. Despite these limitations, teachers demonstrate adaptive capacity by applying digital learning strategies such as blended learning, gamification, and project-based learning. This study concludes that the problems of teachers' digital literacy are multidimensional and require a comprehensive approach through strengthening digital pedagogical competence, institutional support, and adequate infrastructure provision.
