Abstract

Kemampuan numerasi siswa di SD Negeri Ngrenak belum optimal, hal ini disebabkan karena guru belum memperhatikan level-level kognitif AKM pada saat latihan soal sehingga pengabdian ini menawarkan solusi untuk melakukan pembinaan terhadap siswa dalam menyelesaikan soal-soal AKM Numerasi dengan memperhatikan level-level kognitif AKM, yaitu pemahaman, penerapan dan penalaran. Metode pelaksanaan pengabdian menggunakan metode ceramah, pembinaan dan diskusi. Adapun tahapan pengabdian ini meliputi perencanaan, pelaksanaan, evaluasi dan refleksi. Hasil yang dicapai dalam pengabdian ini, yaitu nilai AKM siswa di SD Negeri Ngrenak dapat meningkat pesat, hal tersebut dapat dilihat dari hasil Try Out sebesar 80% siswa mencapai nilai di atas 75. Selain itu, siswa mahir dalam menyelesaikan soal-soal AKM numerasi baik pada level pemahaman, penerapan dan penalaran. Bentuk pembinaan AKM ini sangat efektif untuk memberikan pengetahuan dan ketrampilan siswa dalam menyelesaikan soal-soal AKM Numerasi. Antusias guru dan siswa terkait proses pembinaan AKM sangat tinggi.

Abstract

This study aims to identify research trends on digital-based learning media in the Gen Z era and visualize them. The method used is the descriptive bibliometric analysis method. The research data comes from the database dimensions obtained as many as 548 publication articles that have gone through several stages of data collection, namely identification, screening, eligibility, and inclusion. The results of the study concluded that the highest number of publications in 2024 was 227 publication articles. Indonesia is a pair of country bibliographies that have the largest number of documents and have a major influence on the focus of this research compared to other countries. The top-ranked bibliographic pair of institutions/universities is Yogyakarta State University with a total link strength of 61. The pair of journal bibliographies that have the largest number of documents is the science education research journal. The focus of research with the keyword digital-based learning media in the Gen Z era obtained seven clusters. New themes in this field of research are literacy, Islamic education, younger generation, disruption, the industrial revolution era, the society era, and entrepreneurship. These topics can be selected for further research because this topic still rarely appears in research topics.

Abstract

The use of GeoGebra as an interactive learning medium in geometry has become a major focus in various mathematics education studies. GeoGebra allows dynamic visualization of geometric objects and supports student engagement in understanding concepts more deeply. As the number of publications discussing the use of GeoGebra in geometry learning at the secondary school level increases, a comprehensive review is needed to identify trends, focus directions, and open research gaps. Therefore, this study aims to identify and map trends and research focuses on the use of GeoGebra in geometry learning in secondary schools through a descriptive bibliometric approach. Data in this study were obtained from the Google Scholar database with a total of 480 published articles that have been selected through the stages of identification, screening, eligibility, and inclusion. The results of the analysis show that the publication trend increased significantly in the period 2020–2025, with the highest citation peak occurring in 2022, namely 840 citations. The most dominant journals covering this topic are the Rafflesia Journal of Mathematics Education and the Cendekia Journal. The main focus of the research is divided into six large groups: GeoGebra; geometry; junior high school students; mathematics learning in secondary schools; application of the discovery model; and studies of algebra and problem solving. These findings not only provide a comprehensive overview of the development of GeoGebra research but also reveal potential new themes that can be developed in further studies.

Abstract

Mathematical literacy is an essential competency for students in the Mathematics Education study program, particularly in understanding and solving mathematics problems at the high school/vocational school level. Mathematical literacy encompasses not only the ability to perform calculations, but also the ability to formulate, apply, and interpret mathematical concepts in the context of real problems. This study aims to describe students' mathematical literacy skills in solving Final Semester Exam (UAS) questions for the Mathematics course in high school/vocational school. The type of research used is descriptive with a qualitative approach. The study population was fifth-semester Mathematics Education study program students, with three subjects representing high, medium, and low ability levels, selected by random sampling and having taken the UAS for the related course. The research instruments included test questions and interview guidelines, while data collection techniques included test results, interviews, and documentation. Data analysis was carried out through triangulation with three stages: reduction, presentation, and drawing conclusions. The results showed that the average mathematical literacy ability of students was at a moderate level (average score of 67). High-ability students mastered the aspects of formulate, employ, and interpret, medium-ability students only mastered employ and interpret, while low-ability students had not mastered all three aspects adequately. This finding emphasizes the need for learning strategies that focus more on strengthening the formulating aspect, so that all students are able to understand, formulate, and interpret mathematical concepts comprehensively.

Abstract

The increasing research on the culturally responsive teaching (CRT) approach shows that this approach can improve students' abilities and student participation in learning, so that a more in-depth analysis of the results of these studies is needed. Therefore, the purpose of this study is to review the trend of research results on the culturally responsive teaching (CRT) approach to mathematics learning in Indonesia and visualize them. This research method uses eval__uative and descriptive bibliometric analysis. The sample used in this study came from a database of dimensions of 84 published articles that had gone through several stages of data collection. The results showed that the highest number of publications in 2024 was 54 published articles. The top-ranked bibliographic pair of institutions or universities was Padang State University, with a total link strength of 10. The journal bibliographic pair with the largest number of documents was the SHES journal, which had nine published articles. The document bibliographic pair with the most citations was Taher in 2023, with 80 times. The influential bibliographic author in this study was Atmojo, Idam Ragil Widianto. The focus of the research is divided into three, namely the CRT approach, mathematics learning, and students. New themes in this study, namely elementary schools, mathematics learning, learning, teachers, implementation, private and public secondary schools, the DAP approach, Gen Z, STEAM learning, and students' mathematical abilities. These themes can be used for further research because they are still rare in this research topic.

Abstract

Mathematics Olympiad is a competition to measure and improve students' mathematics skills. Therefore, guidance and coaching of mathematics olympiad is needed which aims to prepare superior seeds both in terms of material and mental, especially for students at SMP Islam Ta'allumul Huda Bumiayu in facing mathematics olympiad. The method of implementing this community service uses the method of material consolidation (25%), practice questions (60%), and interviews or moderation (15%). The stages of community service include planning, implementation, evaluation, and reflection. The results achieved in this community service, namely the development of the national science olympiad (OSN) in the field of mathematics study were 100% implemented and students were very enthusiastic in participating in the development of mathematics olympiad. Students' understanding of the olympiad material and various types of mathematics olympiad questions increased significantly, as seen from the results of the pre-test and post-test, namely 80.2 and 90.35 from each sub-chapter of the olympiad material. Students have a competitive spirit and compete intelligently and students have a reference source in the form of drilling mathematics olympiad questions whose credibility has been tested.
