Abstract

Limits of function is one of sub-topic of Calculus that is complex and difficult to understand. Several studies, both examining misconception and understanding related to function limits, aim to improve teaching and learning. This research is single Subject Research with a single subject, namely by Student of National Mathematics Olimpiad ON MIPA in University. Data was collected through a test instrument consisting of 7 questions on understanding function limits and interviews were conducted to confirm the subject's answers. Data analysis is qualitative. The research results show that 1) Subject can determine the limit value of the function. However, the subject still has a partial understanding. 2) Subject does not understand the meaning of function limits. The subject believes that if there are 2 functions with the same function limit value, then both functions will be the same. 3) Subject can determine the value of the left limit and the right limit from the graph of the given function. 4) Subject cannot formally prove (epsilon-delta) the limit value of the function, the subject does not yet understand what information is given, what information will be sought. The subject is also not able to determine the delta limit in proof problems that have factors 5) Subject can determine the limit value at infinity 6) Subject can determine the value of infinite limit 7) Subject can investigate whether a function is continuous or not continuous. The conclusion of the research is that from 7 understandings of function limits, the subject has 4 perfect understandings regarding left and right limits, limits at infinity and infinity and function continuity. However, the subject was not yet able to prove the limit (epsilon-delta).

Abstract

One of the most crucial abilities for students to cultivate is the capacity to engage in collaborative endeavours. Despite the growing interest in collaboration as a skill required of students, the context of collaboration itself remains unclear. The objective of this literature review is to examine the conceptualisations, definitions and understandings of collaboration as presented in the research literature. Collaboration can be defined as a process whereby members of a group interact with one another in order to fulfil their roles and to solve problems or achieve goals collectively. In order to achieve this, it is essential that responsibility is shared. The most frequently employed indicators are those identified by Trilling and Fadel, namely cooperation, flexibility, responsibility, compromise and communication. It is incumbent upon educators to consider how the design of assessment tasks can be modified to encourage all students in a group to participate, share thoughts, gather resources and ideas, manage tasks, manage time and communicate effectively.

Abstract

High school students enter adolescence, a period full of challenges, including changes in their physical, emotional, cognitive, social, and behavioral aspects. The inability to adapt to these changes often leads to problems. Therefore, problem-solving skills are necessary. This study explores the relationship between students' emotional stability and their mathematical reasoning abilities. The research aims to understand how variations in emotional stability impact the cognitive process involved in mathematical reasoning. A descriptive qualitative approach was used to examine the mathematical reasoning abilities of twelfth-grade students in Bandung. Participants were selected using purposive sampling based on specific criteria related to their emotional stability and reasoning abilities. The instruments included a mathematical reasoning test and an emotional stability questionnaire measured on a Likert scale. The results indicate that students with high emotional stability demonstrate very good mathematical reasoning abilities, meeting all relevant indicators. In contrast, students with medium emotional stability show good reasoning skills, meeting three to four indicators. Students with low emotional stability, however, fall into the poor category, meeting only one or two indicators. These findings suggest that emotional stability significantly influences students' ability to reason mathematically. The study recommends that educators create engaging and supportive learning environments to enhance students' emotional stability and, consequently, their mathematical reasoning abilities. Training programs for students with low emotional stability are advised to help them focus better and improve their cognitive abilities. Future research should further investigate the interplay between emotional stability and mathematical reasoning across different subjects and educational levels to develop more effective educational strategies.

Abstract

This study explores the mathematical concepts embedded in the woven motifs of Buna, specifically Tais Kaimnutu and Buna Panbuat, from the Amanuban community, and their potential integration into mathematics education. Using a qualitative ethnographic approach, the researchers conducted six months of observations, interviews with indigenous weavers and cultural experts, and documentation of woven patterns. The study reveals that Buna woven motifs embody rich mathematical concepts such as symmetry, geometric transformations, fractals, and group theory, while also reflecting deep cultural values, identity, and spirituality. These motifs serve as intuitive artistic and cosmological expressions, with mathematical interpretations offering a new form of cultural appreciation that respects local contexts. Educationally, these motifs support learning across all levels: introducing symmetry and spatial visualization in elementary school; deepening understanding of transformations and congruence in middle school; exploring fractals and algebraic structures in high school; and fostering culturally responsive teaching in higher education through ethnomathematics integrated with mathematical modeling and topology. Beyond pedagogy, the study emphasizes the importance of integrating indigenous knowledge into formal curricula to strengthen cultural identity, community involvement, and empowerment. It highlights ethnomathematics as a transformative bridge linking academic research, cultural preservation, and community development. Future research should explore participatory curriculum design and community perspectives on the mathematical interpretation of indigenous crafts to enhance educational and cultural sustainability.

Abstract

Students learn mathematics through practical applications without applying it. Consequently, the concept images and definitions that students offer do not match. This study examines the gap in mathematical ability between the concept images of professionals in mathematics education and students' concept images of content, including quadrilaterals. This study employed a qualitative approach with a hermeneutic phenomenology method. Sixty-two seventh-grade students were involved in conducting this study. Some instruments, such as quadrilateral-related tests and semi-structured interview questions, were used to collect the data. The results of quadrilateral-related tests and interviews revealed that most students with high mathematical ability, some with medium mathematical ability, and a small number with low mathematical ability have a concept image that matches the definition but cannot produce proof of the properties of a quadrilateral. In addition, a small number of students with high mathematical talents, some with medium mathematical abilities, and a large number of students with low mathematical abilities were unable to completely explain each rectangle's formal definition and properties. This indicates that there are some students whose concept image is low. So, several alternatives and effective mathematics learning should be implemented to facilitate students in enhancing students concept image.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk menumbuhkan kecerdasan logis-matematis warga belajar di salah satu Pusat Kegiatan Belajar Masyarakat (PKBM) di Kabupaten Bandung Barat, Provinsi Jawa Barat. Kegiatan ini dilatarbelakangi oleh hasil observasi bahwa pembelajaran matematika paket B belum mengoptimalisasikan media dalam proses belajarnya termasuk alat peraga. Hal ini disebabkan karena media belum terfasilitasi dengan baik, padahal belajar matematika dengan alat peraga dapat menumbuhkan tantangan bagi pembelajar termasuk alat peraga menara hanoi. Pengabdian terdiri dari beberapa tahapan yaitu observasi, pelaksanaan, dan evaluasi. Dalam pelaksanaan kegiatan warga belajar dibagi menjadi tiga kelompok dan mencoba mencari langkah minimum perpindahan dan menganalisis strategi yang harus digunakan untuk mencapai tujuan. Berdasarkan hasil angket kecerdasan logis-matematis didapatkan bahwa menara hanoi dapat menumbuhkan kecerdasan logis-matematis lebih dari 70% warga belajar, sehingga dapat dikatakan bahwa alat peraga ini cocok digunakan untuk menumbuhkan kecerdasan logis matematis dalam proses pembelajaran khususnya pada materi pola bilangan. This community service activity aims to foster the logical-mathematical intelligence of learning residents at one of the Community Learning Activity Centers (PKBM) in West Bandung Regency, West Java Province. This activity was motivated by the observation that package B mathematics learning had not optimized the media in the learning process, including teaching aids. This is because the media has not been well facilitated, even though learning mathematics with visual aids can create challenges for students, including the Hanoi tower props. The service consists of several stages: observation, implementation, and evaluation. In carrying out the activity, students are divided into three groups and try to find the minimum steps of movement and analyze the strategies that must be used to achieve the goal. Based on the results of the logical-mathematical intelligence questionnaire, it was found that the hanoi tower can foster logical-mathematical intelligence of more than 70% of the learning population, so it can be said that this teaching aid is suitable for growing logical-mathematical intelligence in the learning process, especially in number pattern material.
