Abstract

Variations in competence and confidence among higher education students in mathematical literacy, numeracy, and logical thinking are crucial for developing critical reasoning, problem-solving skills, and the application of quantitative knowledge in both academic and real-world contexts. However, limited research has explored how students from different academic disciplines vary in their competence, confidence, and challenges related to these fundamental areas. This gap in the literature highlights the need for a comprehensive examination of such variations across diverse higher education fields. This study aims to compare the levels of mathematical literacy, numeracy, and logical thinking among university students, focusing on their knowledge, confidence, and the challenges they face. A comprehensive survey was employed, covering several dimensions of mathematical literacy, such as real-world applications of mathematics, numeracy comprehension, numerical self-confidence, and the role of emotions in logical thinking. Drawing on responses from Indonesian university students, the study reveals that students generally perceive their abilities as moderate to good, though significant differences are evident across academic disciplines and levels of study. A notable correlation was found between the focus of students' academic programs and their mathematics literacy, with certain disciplines demonstrating higher competency levels. The findings highlight the importance of integrating practical applications and emotional intelligence into mathematics education to foster greater confidence, knowledge, and engagement. This research contributes valuable insights into mathematical literacy and proposes new strategies to improve teaching practices and curricula. The comparative analysis offers a broader perspective, essential for shaping future assessments in mathematics, logical reasoning, and numeracy literacy.

Abstract

Students often find mathematics a challenging subject and turn it into a scourge for them. Game-based learning, such as “24-card game”, help engage students in a self-paced and fun learning process and thus may overcome students’ math anxiety and promote mental math skills. This research aims to examine how the 24-card game works using the Monte Carlo method and the possibility to overcome students' mathematics anxiety. The meta-analysis method was used to explain Monte Carlo’s simulation to solve the solution for all possible combinations of cards in the game and respectively assign difficulty levels. The student's proficiency level was evaluated based on the divergence value in the number of guesses required to solve the dealt combination at 87% to show full proficiency. The evaluation could also show the math difficulty of advanced operations, such as fractions and grouping games. This game is more efficient in developing students' mental math skills compared to a conventional and rigidly structured classroom lecture.

Abstract

Current research indicates the presence of highly skilled and motivated students with robust computational thinking backgrounds seeking opportunities to leverage their expertise in driving innovation and success in this era. These studies also reveal that students' computational thinking skills vary widely depending on educational resources, curriculum emphasis, and individual aptitude. Nonetheless, there is a growing recognition of the importance of fostering these skills, with efforts underway to integrate them more comprehensively into education systems worldwide, including in Indonesia and Japan, as representatives of developing and developed countries. Therefore, assessing the competency of computational thinking in these two countries would be intriguing. The descriptive qualitative research method was employed to delineate the computational thinking competencies of students in Indonesia and Japan. Student worksheets, specifically designed for this purpose, were utilized to gauge the development of these competencies during the learning process using the Scratch application. The results revealed that students employed various strategies in solving the given geometry problems. On the other hand, geometry is one of the mathematics topics that can identify students' computational thinking using this application. These findings were utilized to categorize students' computational thinking skills in the two countries and to identify potential obstacles students experienced in their efforts to enhance these skills. Nevertheless, these constraints offer significant insights into potential areas for future investigation and enhancement. Subsequent endeavors could prioritize conducting experiments by implementing specific learning approaches or methods that have demonstrated effectiveness in improving students' computational thinking skills. This study not only underscores the potential for expanding research on students' computational thinking skills but also provides an overview of the learning process, learning culture, and students' competence in solving geometry problems with tiered difficulty levels using their computational thinking skills.

Abstract

Indonesia, particularly the Java region, is home to a wealth of folklore rich in moral teachings. Among these, the story of Rama and Sinta is one of the most prominent, and upon initial investigation, it reveals an underlying presence of mathematical concepts, particularly relations and functions. Despite this potential, there is a lack of research on integrating such cultural elements into the teaching of mathematics. This study aims to fill this gap by exploring the use of the Rama and Sinta narrative as a contextual tool for teaching relations and functions. Following the design research method within the Ethno-Realistic Mathematics Education (Ethno-RME) framework, we developed instructional materials for seventh-grade students at a public school in Magelang, Central Java, Indonesia. These materials, consisting of both student and teacher books, were designed to contextualize the mathematical concepts of relations and functions within the cultural narrative. The resulting learning trajectory, consisting of five interconnected activities, not only deepened students' understanding of the mathematical concepts but also reinforced the moral lessons embedded in the folklore. This paper details the development process, implementation, and outcomes of this culturally responsive approach, contributing valuable insights into the integration of local cultural narratives with core mathematical concepts to enhance the learning experience.

Abstract

In junior high school mathematics, exponents are a fundamental topic that underpins the understanding of more advanced concepts such as logarithms and exponential equations. However, many students still struggle to fully grasp this concept, leading to various forms of misconceptions. Using a systematic literature review approach, this study aims to examine the types of misconceptions, their causes, and the implications for teaching and learning. The literature search was conducted through Google Scholar and Dimension AI databases using specific keywords and inclusion criteria, namely: articles discussing the analysis of misconceptions in teaching exponents at the junior high school level, published between 2020 and 2025, and sourced from indexed national and international journals. The selection process yielded four articles that met the criteria and were relevant for further analysis. The review findings indicate that the types of misconceptions found among students include generalization, notation, overspecialization, and mathematical language. The causes of these misconceptions are classified into internal factors (such as incorrect preconceptions and a tendency to memorize without understanding), external factors (such as non-contextual teaching approaches and lack of visual media), and differences in students' academic abilities. These findings imply the need for diagnostic assessment, meaningful learning, the use of concrete media, and differentiated instruction strategies tailored to students' needs to minimize misconceptions and enhance conceptual understanding of exponents.
