Abstract

Realistic Mathematics Education (RME) has gradually influenced the development of mathematics learning worldwide, including in Indonesia. Through the implementation and development of online-based 21st-century education, RME is increasingly proving itself as an effective approach to improving the quality of mathematics teaching and student learning. Learning using the RME approach based on the e-module System aims to become a real learning experience for education and students in implementing mathematical concepts into web-based software systems. The type of research used is pseudo-experimental research with a population in this study of 3 schools, and the number of samples is 147 students. Hypothesis testing was carried out with the N-gain test on the experimental class and control class and the Linear Regression Analysis Test to determine the effect of Gender on improving the learning outcomes of the experimental class. The results of this study show that: 1) There is a difference in the improvement of learning outcomes of classes taught with the RME approach based on the e-module System with conventional learning models; 2) There is no significant difference in the improvement of learning outcomes of students taught using the RME approach based on the E-Module System based on gender characteristics; 3) Gender only contributes 0.1% to the improvement of learning outcomes while 99.9% of other factors.

Abstract

This study analyzes the direct and indirect effects of learning motivation and learning habits on student grade point average (GPA). The study used a quantitative approach with the path analysis method. The research sample consisted of 57 students and was obtained based on the distribution of research questionnaires. The results showed some important findings: First, learning motivation has a significant direct influence on learning habits, with a path coefficient of 0.673, indicating the critical role of Motivation in shaping positive learning patterns. Second, learning motivation was also shown to significantly influence the GPA with a path coefficient of 0.498, confirming its role as a key factor in academic achievement. Thirdly, learning habits did not considerably affect the GPA, with a path coefficient of only 0.253. Furthermore, it was found that learning habits did not play an effective role as a mediator in the relationship between learning motivation and grade point average. The practical implications of this study suggest that strategies to improve students' academic achievement should focus more on strengthening learning motivation without neglecting the importance of forming positive learning habits.

Abstract

STEM and STEAM education has become a strategic learning approach in addressing global challenges in the Industrial Revolution 4.0 and Society 5.0 era, focusing on developing 21st-century skills, such as creativity, critical thinking, problem-solving and collaboration. This study used bibliometric analysis of 535 articles from the Scopus database published between 2014 and 2025 to explore research trends, dominant keywords, geographical contributions, and author and institutional impact. Data analysis conducted with RStudio, VOSviewer, and Excel identified four main clusters: skills development, educational approaches, utilization of STEM in various fields, and use of learning-based tools such as AR and VR. STEM and STEAM education effectively increased student engagement and built cross-disciplinary skills. However, challenges such as gaps in technology access and teacher training still need to be addressed. These results provide important insights for curriculum development, teacher professional training and education policies supporting technology-based learning transformation.

Abstract

This research is descriptive because it aims to describe students' mathematical representation ability. Mathematical representation is related to ways of expressing mathematical ideas. Mathematical representation is divided into verbal, visual/pictorial, and symbolic representations. The subjects of this study were 40 new Mathematics Education study program students. Data were collected using test and interview techniques. Furthermore, the data were analyzed using descriptive and qualitative statistics. The results showed that only 10% of the students had the mathematical representation ability in the good category, 12.5% in the moderate category, 10% in the poor category, and 67,5% in the very poor category. In detail, for verbal skills, there is 2.5% in the very good category, 7.5% in the good category, 17.5% in the moderate category, 15% in the poor category, and 55% in the very poor category. For the ability of visual/pictorial representation, there is 2.5% in the very good category, 7.5% in the good category, 12.5% in the moderate category, 7.5% in the poor category, and 70% in the very poor category. Furthermore, for the symbolic representation ability, 10% is in a good category, 10% in the moderate category, 7.5% in the poor category, and 72.5% in the very poor category. Based on the classroom observation and interview, the low mathematical representation ability is caused by two main things, namely (1) relatively low prerequisite knowledge and (2) mathematics learning, which is dominated mainly by teachers; learning does not provide opportunities for students to develop mathematical representation skills
