Mathematical abilities that students must possess at the level of primary and secondary education must also be possessed by a student of teacher candidates who will teach mathematics. One of the abilities is an analogical reasoning ability. The main objectives of this research are: 1) To describe and analyze analogical reasoning ability of students of mathematics education at the State Islamic Universities (UIN) in Indonesia, 2) To know the differences of analogical reasoning abilities of students of mathematics education at several State Islamic Universities (UIN) in Indonesia. The study was conducted at 6 UINs in Indonesia with a sample of 203 5th semester students using a survey method. This study's results indicate: 1) Analogical reasoning ability in Mathematics Education students consisting of 6 UINs in Indonesia can be seen from the average value in each sample. The acquisition of the average value of UIN Syarif Hidayatullah Jakarta students' analogical reasoning ability is the highest compared to the other 5 UINs with an average mathematical reasoning ability value of 65. 2. There is a difference in mathematics education students' analogical reasoning ability at the State Islamic Universities (UIN) in Indonesia.

In the ever-evolving digital era, teachers are required to be able to integrate technology into the learning process to improve the quality of education. This community service activity aims to develop teachers’ competencies in implementing the 5EIM learning model (Engage, Explore, Explain, Elaborate, Evaluate, Integrate, and Meta-Reflect) based on technology. The methods used include training, mentoring, and classroom implementation evaluation. This activity was attended by teachers from various educational levels with diverse backgrounds in technology utilization. The results of the program showed a significant increase in teachers’ understanding and ability to design and implement the 5EIM-based learning model digitally. Furthermore, the teachers also showed a positive attitude toward the use of technology as a tool to enrich students’ learning experiences. This activity is expected to serve as a model for sustainable and adaptive professional development for teachers in response to the demands of the digital age.

This study aims to determine the effect of the Discovery Learning model on the mathematics learning outcomes of class VIII students at SMP Negeri 1 Siak Hulu in the 2025/2026 academic year. This study uses a quantitative approach. The type used is quasi-experimental research. This experiment is called a quasi-experiment. The population in this study were all students of class VIII of SMP Negeri 1 Siak Hulu in the academic year of 2026. Sampling in this study used a purposive sampling technique by selecting two classes, namely class VIII B as the experimental class and class VIII A as the control class. The original plan for the type of sample for the experimental class and the control class was 34 and 35 students, respectively. However, during the implementation there were students who were absent, so the sample for the experimental class was 32 students and the sample for the control class was 26 students. The research instruments used in this study were pre-test and post-test essay questions to determine student learning outcomes. The data analysis techniques used are descriptive analysis and inferential analysis. Based on the results of the research and the results of the research data analysis that have been carried out, the value of Asymp.Sig (2-tailed) <α was obtained with α = 0.05 and Asymp.Sig (2-tailed) = 0.000 (0.000 <0.05). Therefore, H_0 is rejected and H_1 is accepted, meaning there is a difference between the average learning outcomes of students in the experimental class and the control class. So it can be concluded that there is an influence of the discovery learning model on the mathematics learning outcomes of class VIII students at SMP Negeri 1 Siak Hulu.

Mathematical problem-solving skills are an essential competence for pre-service mathematics teachers, as they are expected to cultivate these skills in their future students. This study aims to describe the problem-solving profiles of pre-service mathematics teachers using Polya’s four stages as an analytical lens. A qualitative case study approach was employed to examine the cognitive processes demonstrated by pre-service teachers while solving mathematical problems. The findings reveal diverse problem-solving profiles, including conceptual understanding shaped by prior experience, logical reasoning used to interpret problem conditions, and the ability to represent problems through mathematical models. These profiles underscore the need for dedicated coursework that enhances mathematical problem-solving skills within mathematics education programs. The study provides insights into the variation of problem-solving profiles and offers implications for curriculum development in the mathematics education department. Keywords: Mathematical problem-solving skills, pre-service mathematics teachers, Polya’s profile, qualitative research

The critical thinking ability is fundamental in learning mathematics so it must be possessed by students as prospective teachers. In fact, the students' mathematical critical thinking ability is still relatively low. In this case, one of the causes is the change in learning system from face-to-face to online learning. One effort that can be done to overcome this issue is to apply interactive multimedia-based learning. Current research was further conducted in this matter, aiming to improve students' mathematical critical thinking ability through interactive multimedia-based learning to support online learning. This quantitative research (quasi-experimental) was carried out by involving prospective mathematics teacher students enrolling in the algebraic structure course in 2021/2022 at Universitas Islam Riau (UIR) as the experimental class and prospective mathematics teacher students at Universitas Pasir Pengaraian (UPP) as the control class. The data were further collected through a mathematical critical thinking ability test which were further analyzed through statistical tests. Based on the results of the t-test, there was an increase in students' mathematical critical thinking ability who received a learning process using interactive multimedia.

Indonesian pupils need help solving problems, particularly in mathematics, due to the need for practice questions with the higher-order thinking (HOT) type. This research aims to develop a reliable and valid tool for assessing students' higher-order thinking skills in mathematics. Developing a test involves gathering requirements, creating questions, assessing answers, running trials, analyzing data, making adjustments, and finally putting everything together. The instrument trial was conducted at SMAN at Majalengka, West Java. The total number of test subjects was 32 students. Research data were collected using a description test. The test instrument consists of 10 descriptions, but only 6 had good validity based on the value of V on the V-Aiken. In addition, the test package produces reliable questions based on Cronbach's Alpha scores. The test results of the instrument showed that the HOTS of mathematics for Grade X students was good. This step provides an overview to teachers in designing valid and relevant instruments.

This study aims to analyze the trend of scientific publications regarding the application of Education for Sustainable Development (ESD) in mathematics learning to students' mathematical abilities in the 2020–2025 period. The method used is bibliometric analysis by utilizing article data from Google Scholar through Harzing's Publish or Perish (PoP) and analyzed using VOSviewer software. A total of 991 articles were analyzed to examine the development of publications, citation patterns, and the relevance of research themes. The results showed a significant increase in the number of publications, with a total of 9,304 citations and an h-index value of 46. The focus of research shifted to the topics of mathematical problem-solving, creative thinking skills, STEM integration, and the implementation of ESD-based curriculum. However, the theme of the effectiveness of the application of ESD on students' mathematical abilities directly is still relatively limited. This research is important because there have not been many studies that systematically map the direction, dominant focus, and gaps of ESD research in mathematics learning, so that it has the potential to hinder the development of sustainable and targeted research. The impact of this research is to provide a strategic reference basis for researchers and educators in developing advanced research and ESD-based mathematics learning innovations that are relevant and have an impact on strengthening students' mathematical abilities
