Abstract

By using technology, learners can better understand mathematical concepts that are relevant to their local culture. Ethnomathematics focuses on the application of mathematics in a cultural context, and educational technology allows for the creation of more interactive and contextual learning media. The purpose of this study is to review articles related to the use of technology in ethnomathematics-based learning media. The Systematic Literature Review (SLR) method was used in this study to review existing literature on the use of technology in ethnomathematics-based learning. There were 14 relevant articles in 2024 selected and analyzed using SLR to determine the opportunities for technology in creating learning media based on local culture. The results of the analysis show that technology and culture have been utilized in mathematics learning and have positive effects. However, to achieve optimal success, special attention needs to be paid to aspects of technology accessibility and the development of materials that are relevant based on local culture

Abstract

This study aims to identify the need for the use of Artificial Intelligence (AI) technology in supporting adaptive mathematics learning. The subjects of this research are students of the Faculty of Teacher Training and Education, University of Mataram, who are enrolled in mathematics courses. This is a descriptive study with a qualitative approach. The data collection instruments used are observation and questionnaires. The results of this study indicate that: (1) 96% of students are accustomed to using Artificial Intelligence (AI) technology for learning, with 31% reporting usage "every day" and 58,6% reporting usage "several times a week", etc.; (2) several AI-integrated applications commonly used by students include ChatGPT (Open AI), Gemini, Meta, Perplexity, Question AI, etc.; (3) AI technology is capable of providing students with more detailed information from various references, even by simply uploading a photo or image, and it can assist with academic tasks, though attention must still be given to limitations and ethics.

Abstract

Abstract This research aims to investigate the effectiveness of the Problem-Based Learning (PBL) model in enhancing the learning activities and outcomes of seventh-grade students in SMPN 6 Mataram, particularly for students with diverse mathematical abilities. Employing a collaborative Classroom Action Research (CAR) approach, the study was conducted in three cycles consisting of planning, implementation, observation, and reflection. Data collection methods included observation of learning activities and achievement tests. The research findings revealed a significant increase in student learning engagement, from 59.37% in cycle I to 81.25% in cycle III, as well as an improvement in learning mastery from 59.52% in cycle I to 85.71% in cycle III. These findings indicate that the Problem-Based Learning (PBL) model successfully encouraged active student involvement in learning activities and enhanced their understanding of the subject matter. This research recommends the adaptive and creative implementation of the Problem-Based Learning (PBL) model, as well as the development of varied learning activities to cater to the needs of students.

Abstract

Pendidikan merupakan sebuah proses pembelajaran bagi setiap individu. Dalam sistem pembelajaran, ada banyak cara atau model-model yang dapat diterapkan dalam perkuliahan agar suasana belajar mengajar terasa lebih menyenangkan yaitu model pembelajaran diskusi, kolaboratif, case method dan sebagainya. Pada penelitian ini digunakan model pembelajaran diskusi dan case method untuk mengetahui apakah ada perbedaan antara kedua model tersebut, maka digunakan uji nonparametrik dua sampel independen. Uji yang digunakan untuk membandingkan perbedaan antara dua sampel yang independen yaitu Uji Mann Whitney dan Uji Kolmogorov Smirnov. Alasan digunakan metode tersebut, karena metode ini dapat menilai apakah dua sampel independen yang diamati terdapat perbedaan atau tidak secara signifikan. Tujuan penelitian ini adalah untuk menguji apakah ada perbedaan nilai yang signifikan antara kedua model pembelajaran tersebut dan melihat metode manakah yang terbaik dengan melihat Mean Square Error (MSE) terkecil. Hasil penelitian menyimpulkan bahwa perhitungan pada pengujian hipotesis Uji Mann Whitney dan Uji Kolmogorov smirnov terhadap model pembelajaran case method dan diskusi yaitu terima H0 artinya tidak ada perbedaan bermakna antara model pembelajaran case method dan diskusi. Berdasarkan hasil statistik Uji Kolmogov Smirnov ternyata lebih baik dibandingkan dengan Uji Mann Whitney. Karena Uji Kolmogov Smirnov memiliki nilai Error atau MSE lebih kecil dibandingkan dengan Uji Mann Whitney.

Abstract

This research is motivated by the low numeracy skills of students in Indonesia, particularly in mathematics, with only 28% achieving proficiency at Level 2, far below the OECD average. The research problem includes questions about the effectiveness of Interactive Mathematics Learning Media (GeoGebra and Website) in improving students' numeracy skills in Geometry Transformation material. The aim of the research is to evaluate the effectiveness of this learning media, and the results are expected to provide an alternative for teachers in enhancing students' numeracy skills, which is crucial in addressing the wide educational quality gap in Indonesia compared to other countries, especially in terms of students' numeracy abilities. This research is also expected to provide recommendations to support the improvement of mathematics education quality at the junior high school level. This study is a case study involving 2 teachers and 8 students. The interactive mathematics learning media, integrating GeoGebra and the website, is effective in improving students' numeracy skills in geometry transformation material. The effectiveness of the interactive mathematics learning media can be seen through sufficient activities that allow students to explore the properties of translation, rotation, reflection, congruence, and dilation. Students' understanding of these properties in geometry transformation is followed by activities in solving geometry-related problems. Finally, conclusions are drawn on techniques for solving problems related to geometry transformation material.

Abstract

One of the most effective strategies to improve mathematics teachers' professional competency is providing regular professional development workshops and training sessions for teachers. The aim of this study is to answer the following research questions: (1) How to design PD program for mathematics teachers in Indonesia through online workshop? (2) What are areas that need to be improved so that the program works as planned the next time? A “design research” method adopted for analyzing the process of PD program through collaboration CAR. The participant in this study were 24 mathematics teachers from 12 provinces. Data were collected through evaluation forms, focus group discussion, group meeting and learning logs, then the data were analyzed using grounded theory approach through the process of open, axial, and selective coding. 51% of participants considered the workshop to be very good, and 49% provided suggestions for improvement for further implementation. The two biggest factors to improve are adjusting the time to suit the participants and considering the technical issues that teachers might face. Based on the evaluation form each week, teachers considered that they need to join wokshop related to related to the Kurikulum Merdeka implementation, teaching media, ICT integration, and book publishing.
