Abstract

The "realistic" concept in Realistic Mathematics Education (RME) is often confined to everyday contexts. In contrast, for aerospace engineering students, realistic mathematics should reflect the mathematical applications in their academic and future professional environments. This study aimed to design and evaluate instructional activities grounded in RME principles, integrating mathematics mobile applications to support conceptual understanding and reasoning. Using a design research approach, the study involved a questionnaire distributed to alums and third-year students, followed by two implementation cycles with first-year aerospace engineering students. The focus was on integral strategies in calculus, utilizing Photomath to bridge informal and formal mathematical reasoning. Results indicate that students engaged actively with the applications and demonstrated improved reasoning skills, particularly in inductive and imitative reasoning. This study highlights the potential of contextualized digital tools in supporting realistic mathematics learning in higher education. It suggests directions for aligning university-level mathematics with its practical applications in other disciplines, such as aerospace engineering.

Abstract

Mathematical literacy and self-regulated learning (SRL) are essential competencies for students' success in mathematics. However, research on their intersection remains fragmented, lacking a comprehensive overview of trends, key themes, and influential contributions. This study used Google Scholar and Publish or Perish to conduct a scoping review and bibliometric analysis of mathematical literacy and SRL research from 2009 to 2023. The analysis included publication trends, citation patterns, co-word analysis, and collaboration networks. The findings showed a significant increase in research after 2015, with peaks in publications in 2021 and 2022. Key themes include cognitive strategies, motivation, pedagogical approaches, technological integration, and assessment methods. The most cited works emphasize SRL's role in problem-solving, metacognition, and technology-enhanced learning. Collaboration networks indicate that research is dominated by North American, European, and Australian institutions, with limited contributions from developing regions. The study suggests expanding AI-enabled SRL research, teacher professional development, and culturally diverse frameworks to enhance mathematical literacy instruction globally. These insights contribute to advancing evidence-based instructional models that integrate Technology, self-regulation, and mathematical reasoning to improve learning outcomes.

Abstract

Computational thinking skills are systematic ways of thinking that involve formulating a problem, deconstructing the problem, and communicating the solution. The development of students' computational thinking ability is significant; therefore, knowing the obstacles is essential. The purpose of this research is to find out students' learning obstacles in computational thinking. This qualitative research uses a phenomenological approach that describes the meaning of certain concepts related to life experiences for some individuals. The population in this study is one of the high school class XI in Bulukumba district. The subjects in this study were three students in the high, medium, and low categories. Data collection techniques in this study used the following instruments: 1) math test question instrument, 2) interview. The results of this study are (1) ontogenical obstacle in the form of students having difficulty in making models (abstraction stage) because they are wrong in capturing information and do not understand in making mathematical models, (2) epistemological obstacle in the form of students having difficulty in solving problems because the problems given have never been encountered, and (3) didactical obstacle in the form of not understanding the correct writing of permissiveness, this is due to the absence of emphasis on correct permissiveness during learning. This research is expected to help teachers overcome students' computational thinking obstacles.

Abstract

This research explores the contributions of Girard Desargues, a pivotal but often overlooked mathematician in geometry. The study aims to provide insights, inspire interest, and evaluate the understanding of prospective mathematics teachers regarding Desargues' contributions, particularly his work on projective geometry. Employing a qualitative approach, the research integrates a literature review and a case study. Literature data were sourced from academic journals and books, while the case study involved interviews with students from five mathematics education classes. Open-ended interviews assessed students' familiarity with Desargues and their ability to comprehend and apply his theorem. Data were analyzed through meta-analysis and thematic analysis. The findings categorize student responses into three levels: Medium of Desargues and Desargues Theorem, Intermediate Knowledge of Desargues and Desargues Theorem, and Low of Desargues and Desargues Theorem. The results underscore varying levels of awareness among future mathematics educators and suggest that integrating historical mathematical insights into education may support a deeper understanding of concepts.

Abstract

Teacher personality competence, which includes ethical maturity, reflective self-development, and a student-centered orientation, is vital to effective mathematics instruction at Madrasah Ibtidaiyah. However, this crucial aspect remains overlooked mainly in instructional design, limiting the potential for meaningful and ethical learning experiences. This study explores how personality competence is demonstrated in classroom practices and contributes to high-quality mathematics teaching. Utilizing a qualitative approach and the Didactical Design Research (DDR) framework at the prospective analysis stage, the research involved six sixth-grade teachers from six different Madrasah Ibtidaiyah in Bandung Regency. Data were collected through classroom observations, in-depth interviews, teacher reflection sheets, and instructional document analysis. Data were analyzed using the three-stage framework of data reduction, data display, and conclusion drawing/verification through an iterative process to identify patterns and inform the subsequent DDR phases in the context of joyful mathematics learning at MI. Findings revealed that teachers scored at level 3 for moral, emotional, and spiritual maturity, level 1 for reflective self-development, and level 2 for student-centered orientation. These findings suggest that while MI teachers show emerging awareness of personality competence, most remain at early developmental stages, highlighting the need for structured support to foster ethical leadership, reflective practice, and student-centered teaching. Teachers with strong personality competence exhibited discipline and consistency and served as moral role models. Furthermore, they effectively managed classrooms and actively engaged students in mathematical learning. These results offer insights for developing instructional designs prioritizing teacher personality competence as a critical factor in educational quality.

Abstract

Research on relational thinking has been widely conducted; however, no analysis of these studies has been carried out so far. This research aims to analyze the distribution of research related to relational thinking in mathematics at elementary and high school levels, which was conducted from 2016 to April 2024. This study employs the Systematic Literature Review (SLR) method, focusing on articles indexed in Scopus, ERIC, ScienceDirect, and Google Scholar. The results of the Systematic Literature Review (SLR) show that: (1) there were 30 studies on relational thinking ability in mathematics conducted; (2) eight studies were conducted abroad, while 22 were conducted in Indonesia; (3) arithmetic was the most common topic in research on relational thinking; (4) the majority of studies on relational thinking ability have been carried out at the junior high school level; (5) of the 30 articles, 14 are indexed in Sinta, 7 in Scopus, and 9 are indexed only in Google Scholar; (6) there are two definitions of relational thinking used by researchers. These findings serve as a basis for determining future research topics related to relational thinking ability.

Abstract

Integrating computational thinking into Programme for International Student Assessment (PISA) assessments presents a significant challenge for Indonesian students, particularly in mathematics education. Despite its crucial role in problem-solving, computational thinking has not been widely implemented by students due to the presence of learning obstacles. This study aims to identify the learning obstacles that junior high school students encounter in understanding systems of linear equations in two variables, specifically about their computational thinking abilities. A qualitative approach with a phenomenological method was employed. Research instruments included a computational thinking test and a semi-structured interview guide. Data were collected from 20 students at a junior high school in Wonosobo Regency, Indonesia. Data analysis consisted of three stages: reduction, display, and conclusion. The findings reveal that students experience three types of learning obstacles—epistemological, ontogenical, and didactical when engaging with systems of linear equations in two variables, indicating that these obstacles hinder the development of their mathematical computational thinking skills.

Abstract

Students' understanding of the concept of circles is still low, which can be influenced by differences in presentation in textbooks between countries and curriculum. Therefore, this study aimed to analyze by comparing the material and questions on the topic of circles in Indonesian and Indian mathematics textbooks in terms of facts, concepts, principles, cognitive levels, PISA framework, and problem-solving questions. This study was conducted using a descriptive-comparative method with a qualitative approach. The objects of this study were Indonesian mathematics textbooks Merdeka Curriculum for grade XI and Curriculum 2013 for grade VIII, as well as Indian mathematics textbooks for grade X. The results showed that the three books had different focuses in delivering the material. Indian books emphasized formal proofs and geometric visualizations and included exploratory activities based on practice. Indonesian books, Curriculum 2013, focused more on contextual activities and gradual discovery of concepts, while Merdeka Curriculum books emphasized conceptual understanding through an exploratory and reflective approach. The questions in the Merdeka Curriculum book are more cognitively diverse, in line with the PISA framework and Polya's problem-solving stages. This finding is essential for developing adaptive textbooks that support higher-order thinking and 21st-century mathematical literacy.
