Abstract

This research uses the Systematic Mapping Study (SMS) method to identify knowledge trends in beliefs about the nature of mathematics, learning, and learning mathematics and identify new development opportunities for further research. The Systematic Mapping Study (SMS) method is the initial stage for selecting primary sources in a literature study. The Scopus database was used for SMS, then 171 articles were found ready for further analysis. The results show that mathematical belief has become a current research trend. The keywords are "beliefs." The new trending keyword is "pre-service teachers." The thematic map shows thirteen clusters, where the motivation, pre-service mathematics teachers, mathematics education, beliefs, and attitudes clusters are the motor themes currently a global challenge. This means there are still great opportunities to research this theme to complete the knowledge puzzle. In closing, 41 articles are primary articles related to this theme. Three of them, namely articles from Stipek et al. (2001), Beswick (2012), and Felbrich et al. (2012), can be seen as primary references.

Abstract

Background: Understanding mathematical concepts is essential for students, as it forms the basis for developing other mathematical abilities. Many students struggle with abstract mathematical ideas, particularly in geometry.Aim: This study aims to examine the validity, practicality, and effectiveness of GeoGebra-based interactive multimedia in enhancing students’ understanding of triangles and quadrilaterals.Method: This study employed a Research and Development (R&D) approach using the ADDIE model, which consists of Analysis, Design, Development, Implementation, and Evaluation phases. The subjects involved were seventh-grade students at a junior high school. Validation of the product was conducted by two material experts and two media experts. Practicality was assessed using student response questionnaires, while effectiveness was measured through a quasi-experimental design involving a pretest-posttest control group. Data were analyzed using descriptive statistics and inferential analysis to determine the improvement in conceptual understanding.Result: Validation scores reached 88% (material) and 88.2% (media), indicating high validity. Student feedback showed positive responses toward the multimedia's usability and engagement. The experimental group outperformed the control group, with a higher average score, demonstrating the effectiveness of the developed multimedia.Conclusion: GeoGebra-based interactive multimedia is a valid, practical, and effective tool for improving students’ understanding of mathematical concepts, particularly in triangle and quadrilateral topics. Its integration into classroom instruction enhances engagement and supports meaningful learning experiences. Future research is recommended to investigate the long-term effects of such multimedia on students’ conceptual retention, its application to other mathematical domains and grade levels, and its integration with collaborative or inquiry-based learning approaches.

Abstract

The development of technology has a significant impact on the world of education. One of them is the use of games as a learning medium. This study aims to develop an educational game integrated with a live worksheet. The development research was conducted using a design thinking approach. The design thinking stages are carried out through five steps: empathize, define, ideate, prototype, and test. The feasibility of educational games is reviewed based on expert assessments, the practicality of educational games is reviewed based on student response questionnaires, and the effectiveness of educational games is reviewed based on the results of field trials. A total of thirty students of SMP Muhammadiyah 5 Semarang became research respondents. The study results showed that educational games are feasible for mathematics learning, with an Aiken V value of 0.93. The practicality test results showed that students responded to 88.67%, with a very good category. The effectiveness test of using educational games with SPSS using the Wilcoxon Signed Test obtained a Sig. 2-tailed value of 0.000 <0.05. This shows that educational games can improve students' mathematical thinking skills in data presentation materials. This study suggests improvements in creating educational games that need to pay attention to interesting storylines and the placement of practice questions to increase students' motivation in learning mathematics.

Abstract

A braid is any sequence of crossings of the -strand braid with a positive number n, provided none of the strands are self-crossing. The idea is that braids can be organized into groups, in which the group operation is *, which means: “do the first braid on a set of strands, and then follow it with a second on the twisted strand”. This study dealt with the formulation of additional basic properties of mathematical braids and the connection of mathematical braids to exponential theorems. Moreover, the researchers developed a program that could generate the total number of crossings and the total number of generators in an n-strand braid with a positive number n.

Abstract

Mathematical Problem Solving Reviewed from Emotional Intelligence through Metacognition: A Literature Review. Metacognition is an essential part of the math problem-solving process, with emotional intelligence helping to maintain student consistency and focus. Objectives: This study aims to provide an overview of research related to the role of metacognition in mathematical problem solving, particularly from the perspective of emotional intelligence, in the period 2013 to 2024. It focuses on how emotional intelligence affects monitoring, evaluating, and controlling cognitive states and regulating students' interpersonal interactions in problem-solving. Method: This study used the PRISMA Method (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) to select relevant literature. Data analysis was conducted with the help of VOSViewers and Bibliometrix R-Package software, which enabled the mapping of relationships between variables and identifying major trends in research. This study focused on articles that explored metacognition in mathematical problem-solving and the impact of emotional intelligence on this process. Findings: The results of this literature review show a 1.21% decrease in metacognition research trends from 2013 to 2024. Metacognition is connected to student variables, cognitive systems, problem-solving strategies, working memory, self-efficacy, active learning, and reflection. The integration of metacognition and emotional intelligence emphasizes their role in mathematics education. Conclusion: This study provides insights for further research on mathematics problem-solving regarding emotional intelligence through metacognition. In addition, variables such as active learning, problem-solving skills, math anxiety, student characteristics, and math awareness can be used as research references relevant to the current generation.        Keywords: metacognition, mathematics, problem-solving, emotional quotient. DOI: http://dx.doi.org/10.23960/jpmipa/v25i1.pp399-418
