Abstract

This research aims to develop a guidebook for the use of GeoGebra in creating mathematics learning media based on ethnomathematics for university students in mathematics education study program at Pattimura University PSDKU Maluku Barat Daya. The method used in this research is Research and Development (R&D) with 4D model developed by Thiagarajan et al. (1974) which consists of 4 stages, namely Define, Design, Develop and Disseminate. This method and model are very feasible and systematically supports the development of the guidebook. By involving 2 validators, namely material experts and linguists, the draft of the guidebook was then revised and tested on a small limited group. Furthermore, based on descriptive statistical analysis and qualitative descriptive analysis, it can be concluded that the reference book using GeoGebra has been successfully prepared and meets the criteria of valid and effective. In addition, the use of this guidebook can also increase students' knowledge in understanding material related to cartesian coordinates, especially in drawing graphs of linear functions, quadratic functions, polynomials, trigonometric functions, exponent functions, and logarithms.

Abstract

This study aims to analyze the global trend of computational thinking research in mathematics learning through a bibliometric approach. The analysis was conducted on 536 documents retrieved from the Scopus database during the period 2007–2024 using the PRISMA method and analyzed through RStudio and VOSviewer software. The results show an average increase in publication trends of 31.04% each year, with the largest contribution coming from Vanderbilt University and the dominance of publications by authors from the United States. The most prolific source is the ACM International Conference Proceeding Series with influential authors include Gautam Biswas and Shuchi Grover. Keyword mapping revealed six main thematic clusters, focusing on computational thinking integration, digital tools, and its relationship with mathematics and STEM education. Five emerging keywords were identified—systematic review, GeoGebra, CT-Tools, mathematics lesson, and ChatGPT—signaling new directions for future research.

Abstract

The people of Moa Island have a cultural heritage in the form of Lutur Batu. Lutur Batu is a construction of large stones arranged side by side to form a circular wall. Lutur Batu is used to close village boundaries and as a garden fence which aims to protect plants from wild animals. This research aims to determine ethnomathematics studies on Lutur Batu on Moa Island. The ethnomathematics study of Lutur Batu on Moa Island in this research is expected to provide a deeper understanding of the local wisdom of the people of Moa Island, as well as contribute to the recognition, maintenance, and preservation of cultural heritage with mathematical value in the region. Furthermore, an understanding of the geometric patterns and construction of Lutur Batu can be adopted in mathematics learning at school to increase students' interest in learning and understanding of mathematical concepts.This qualitative research focuses on an in-depth understanding of ways of thinking and using mathematics in the traditions and practices of making Lutur Batu in Moa Island. The results of the analysis on Lutur Batu and the manufacturing process showed that there are mathematical concepts such as circles, cylinders, comparisons, and statistics. Lutur Batu and the Mathematical concepts contained therein can be used in Mathematics learning at school to enrich learning materials, increase learning motivation and students' understanding of Mathematics concepts. Apart from that, it can increase students' insight and knowledge regarding the cultural heritage of Moa Island

Abstract

Using software in mathematics learning can improve students' soft and hard mathematics skills at the high school and college levels. Therefore, using software in the learning process is important, including in learning Differential Equations. This research examines the use of the Python programming language with Jupyter Lab software and the SymPy library in solving ordinary differential equation problems symbolically in the Differential Equations course. The use of the Python programming language in Differential Equations learning includes solving linear ordinary differential equations of first-order, second-order, higher-order, and the Laplace transform. This research also examines the effect of using Python on the learning outcomes of differential equations of Mathematics Education Study Program students, Study Program Outside the Main Campus, Pattimura University. The population in this quantitative research is all students who programmed differential equations courses in the even semester of the 2023-2024 academic year as many as 19 students. The Python programming language can be used to solve differential equation problems symbolically easily, quickly, and accurately. In addition, using Jupyter Lab makes the process of solving differential equation problems easier and more interactive. Furthermore, t-test results show that the use of Python in learning differential equations can improve students' learning activities and learning outcomes. Using the Python programming language with Jupyter Lab software and the SymPy library can be developed to create teaching materials, textbooks, and reference books for Differential Equations courses.

Abstract

The mentoring program for the development of AI-assisted ethnoscience-based LKPD at SD Negeri Tiakur aims to enhance teachers' skills in designing LKPD that are relevant to the local culture. This training is motivated by the low utilization of technology in learning in border areas such as the Maluku Barat Daya Regency, as well as the insufficient integration of local culture in the learning process. The methods employed include socialization, training, evaluation, and program sustainability. The evaluation results show an 81% improvement in teachers' skills based on the N-gain test. This program has produced attractive, interactive, and contextual LKPD, blending local cultural elements such as traditional dances, weaving, and the koli tree with modern scientific concepts. The use of technology tools such as Canva and Quizizz has made it easier for teachers to design and evaluate LKPD. This program not only improves the effectiveness of learning but also promotes the preservation of local wisdom and supports the achievement of inclusive, high-quality, and contextual education.

Abstract

The low mathematical literacy skills of junior high school students in Indonesia, especially those living in the Small Border Islands, require serious attention from various stakeholders. Improving students’ mathematical literacy is a shared responsibility that can begin with introducing the form of PISA mathematical literacy questions to junior high school students. One effort to achieve this is through an ethnomathematics-based mathematical literacy competition. This competition aims to provide knowledge and understanding of PISA mathematical literacy to students in the Small Border Islands, particularly on Moa Island. The activity was carried out as a form of community service by lecturers and students, consisting of four stages: initial observation, socialization, implementation, and evaluation. The participants of this competition were students from seven junior high schools on Moa Island, with a total of 57 participants. The increase in participants’ knowledge regarding PISA mathematical literacy question forms was measured using a questionnaire. The results showed an improvement in participants’ understanding before and after participating in the competition. However, test data also indicated that the mathematical literacy skills of students on Moa Island remain relatively low. Therefore, sustainable programs are needed to improve the mathematical literacy skills of students in the Small Border Islands, including Moa Island.

Abstract

One area in Southwest Maluku Regency that still maintains the culture of its people is Lakor District. Parts of culture that are still maintained today are Lakor weaving, traditional houses, lutur, traditional games, traditional dances, and others. On the other hand, mathematics learning in schools does not accommodate these diverse cultures. Ethnomathematics learning is a way of utilizing local culture as a means of introducing mathematical material. Ethnomathematics-based learning training activities with the help of Geogebra software were carried out with a percentage of 98.83%. Based on 10 indicators of implementation, this training activity is in the very good category and helps teachers make learning more creative and innovative
