Abstract

This article discusses the comparison of trends in mathematics education research in Indonesia and Australia. There are significant differences in research approaches, research focuses, and issues addressed in both countries. Mathematics education research in Indonesia often focuses on improving teacher capabilities, the use of technology in mathematics learning, and the influence of teaching approaches on mathematics learning outcomes. In Australia, research also involves studying mathematics curriculum, effective teaching strategies, inclusion issues in mathematics learning, and the use of technology in teaching. The research approaches also differ, with Indonesia tending to use quantitative approaches and Australia using both quantitative and qualitative approaches. This article provides valuable insights for the development of mathematics education in both countries. By learning from and sharing experiences with each other, both countries can leverage their strengths to enhance the quality of mathematics education at the national level.

Abstract

This Community Service (PKM) aims to build a sustainable and creative learning environment at SMA Swasta Yapim Taruna Stabat. This program was motivated by the lack of students' creative activities and the dominance of gadget use that inhibits social interaction and innovation in learning. This PKM activity involves various programs, such as entrepreneurship, gadget-free days in class, library cleanliness, and reading corners (literacy corners). The PKM implementation method includes initial observation, preparation of work programs, and implementation of various activities that last for one month. The results of this activity show an increase in student creativity in utilizing available resources, increased awareness of the cleanliness of the school environment, and increased social interaction through literacy and entrepreneurial activities. In conclusion, this PKM activity succeeded in having a positive impact on the learning environment at SMA Swasta Yapim Taruna Stabat. Suggestions for the sustainability of this program are the need for further monitoring and mentoring so that the results achieved can continue to grow and provide long-term benefits for students and schools.

Abstract

Mathematics is a universal science that is useful for human life and also underpins the development of modern technology. In general, students find it difficult to learn mathematics due to its abstract nature, which leads to low learning interest. Therefore, contextual learning that is closely related to their daily lives is needed, one of which is ethnomathematics learning. Ethnomathematics learning is integrated with educational games to further increase the appeal of mathematics learning. This study aims to measure the validity, practicality, and effectiveness of the developed educational game. The research uses the 4D model, which includes define, design, development, and disseminate stages. The practicality test was conducted by distributing questionnaires to teachers and students. Meanwhile, the effectiveness test was carried out by giving questionnaires to observers and reviewing students' learning outcomes. The results showed that the developed media was highly valid, with a percentage of 86.7% for the material and 94% for the media; very practical, with teacher and student response percentages of 94.7% and 86.2% respectively; and effective, with an observation result percentage of 91.7%. The learning outcome test showed that 74.28% of students met the Minimum Mastery Criteria. Therefore, the Lagia traditional musical instrument-based educational game is suitable for use in mathematics learning
