Abstract

When solving problems, the spontaneous actions of students identified as slow learners (SL) often reflect their cognitive limitations. This study analyzed students' SL understanding of mathematical concepts through representational gestures as a means of communication in constructing concepts. A qualitative case study was conducted in a public junior high school in Lamongan Regency. From eight SL students identified through IQ tests and teacher interviews, only three consistently used representational gestures and were selected as the subjects. Although limited, this sample enabled an in-depth analysis while acknowledging restricted generalization. Data were collected through functional tasks, gesture observations, and interviews and were then analyzed interactively through data reduction, display, and conclusion drawing. The results showed that SL students frequently used hand gestures to represent graph axes or intersection points but misinterpreted variable relationships. They could only classify objects based on conceptual conditions, while other indicators of understanding were not attained. These findings suggest that teachers should consider students’ gestures not only as spontaneous expressions but also as diagnostic cues for misconceptions and as a support for mathematical communication.

Abstract

Many students encounter learning obstacles when understanding the volume of cylinders and cones; however, few studies have explicitly integrated these obstacles into didactic design. This study aimed to develop a didactic design to address specific learning obstacles in understanding the volume of cylinders and cones. Using a Didactic Design Research (DDR) approach grounded in Brousseau’s Theory of Didactic Situations, the study involved 28 seventh-grade students and a mathematics teacher from a junior high school in Pontianak, selected through purposive sampling. Data were collected through observations, diagnostic tests, and interviews and then analyzed qualitatively using interpretative and critical techniques. The didactic design consisted of four didactic situations: action, formulation, validation, and institutionalization, implemented in classroom practice. The institutional phase revealed several limitations, particularly a lack of sufficient scaffolding and inadequate visual support for students’ spatial reasoning. The findings indicate that addressing epistemological obstacles, such as misconceptions regarding the interpretation of height and base area in three-dimensional solids, can enhance students’ conceptual understanding. The study suggests that integrating learning obstacle analysis into didactic design helps refine future implementations to better anticipate students’ cognitive development.

Abstract

Children with autism spectrum disorder (ASD) often have difficulty understanding abstract concepts, such as monetary values, due to limitations in executive functioning and concept generalization. This study aimed to develop and test a learning trajectory for understanding monetary values through a modified Monopoly game according to the characteristics of autistic students. The study employed a design research approach with validation type, using hypothetical and actual learning trajectory (HLT-ALT) analysis through the stages of preparation, design experiments (pilot and teaching experiments), and retrospective analysis of the data. The research subjects were eight autistic students at the junior high school level at SLB Bina Autis Mandiri, Indonesia. Data were collected through student activity sheets, observations, interviews, and documentation and then analyzed qualitatively. The results showed that the learning trajectory consisting of four activities (playing modified Monopoly, recognizing the value of money, counting the number of pictorial patches of money, and adding up the value of money) effectively helped students gradually understand the concept of monetary value. Game-based activities also increased students' engagement and understanding of the material. This study contributes to a replicable and inclusive learning trajectory that integrates structured gameplay with mathematical reasoning for students with autism.

Abstract

This study addresses a gap in the literature concerning the combined influence of stress and sleep duration on academic performance, particularly in demanding mathematics courses like Basic Statistics. Among mathematics education students—who rely heavily on concentration and logical reasoning—stress and poor sleep may significantly affect learning outcomes. Conducted at a state university in Surakarta, Indonesia, the research aimed to examine the associations between perceived stress, sleep duration, and course performance in 45 first-semester students who had completed Basic Statistics. A non-parametric quantitative design was used, with data gathered via the Perceived Stress Scale (PSS-10), a sleep duration questionnaire, and final course grades. Analyses employed chi-square tests and correspondence analysis. While no statistically significant relationships emerged, the correspondence analysis revealed intriguing proximity patterns: moderate-to-high stress and short-to-adequate sleep categories clustered near higher performance, hinting at possible nonlinear or adaptive effects. These findings, though preliminary, suggest that optimal—not minimal—stress and sufficient sleep may support academic achievement. The study underscores the need for expanded research with larger, more diverse samples to better understand these complex dynamics and inform holistic student support strategies in mathematics education.

Abstract

Computational thinking (CT) is a vital 21st-century skill in mathematics education, enabling students to solve problems systematically through decomposition, pattern recognition, abstraction, and algorithmic thinking. However, students’ mathematical disposition—encompassing beliefs, habits of mind, and affective tendencies—may significantly influence CT development. Guided by the affective–cognitive interaction model, this study aimed to explore how mathematical disposition shapes students’ CT skills, particularly in solving systems of three-variable linear equations using self-constructed, flowchart-supported algorithmic representations. A descriptive qualitative approach was adopted, with six students (two each from high, medium, and low disposition levels, identified via questionnaire) participating. Data collection involved a disposition scale, CT test, interviews, and documentation. Findings revealed that high-disposition students successfully demonstrated all CT indicators and produced coherent flowcharts. Medium-disposition students showed variability: some met all criteria, while others faltered in algorithmic design. Low-disposition students managed only basic decomposition and pattern recognition, with incomplete abstraction and fragmented flowcharts. These results suggest a strong link between affective factors and cognitive performance in CT tasks. Implications highlight the importance of integrating disposition-aware scaffolding—such as interactive visual tools and guided reflection—to support diverse learners and enhance CT development in mathematics classrooms.

Abstract

Although Realistic Mathematics Education (RME) promotes deeper conceptual learning, empirical evidence mapping different types of cognitive loads in university engineering mathematics is limited. This mixed-methods study profiled intrinsic, extraneous, and germane cognitive loads among 76 first-year aeronautical engineering students working on RME-based task, a contextualized double integral problems modelling aircraft wing surface. We measured load components with a CLT questionnaire that adapted from Leppink et.al and mental effort with the Paas scale, then triangulated findings with student reflections and observations. Correlations showed intrinsic and germane load related to students’ mental effort, while extraneous load was minimal, suggesting clear task design. Multiple regression analysis clarified that the germane load was the main unique predictor of mental effort, whereas intrinsic complexity and extraneous factors contributed little uniquely. Qualitative data confirmed that students used strategies such as breaking tasks into sub-steps, activating prior knowledge, and peer explanation to manage effort. We propose an RME–CLT alignment framework that scaffolds intrinsic difficulty, minimizes extraneous processing, and cultivates germane engagement through reflective context-rich tasks. The findings also inform the design of cognitively efficient engineering-mathematics curricula. Thus, it offers practical guidance for designing cognitively efficient engineering mathematics instruction and recommends future studies using longitudinal and real-time measures.

Abstract

This study addresses the need to improve fifth-grade students’ problem-solving skills and learning interest in spatial geometry—a topic often perceived as abstract and challenging—by developing an Augmented Reality (AR)-based instructional medium integrated with the e-IM3 (intelligent, meaningful, mindful, joyful) model. Grounded in the ADDIE framework, the research encompassed the analysis, design, development, implementation, and evaluation phases at SDN Kwadungan Lor, Ngawi, East Java. Initial analysis via diagnostic tests and teacher interviews confirmed low baseline performance and motivation levels. The resulting AR-e-IM3 media underwent expert validation and readability testing, achieving high validity scores (media: 3.79; problem-solving instrument: 3.42; and interest instrument: 3.98). A limited trial (n = 10) and a large-scale trial (n = 32) demonstrated strong practicality (88% and 84.5%, respectively). Effectiveness was evidenced by moderate N-Gain improvements in problem-solving skills (0.58 and 0.51) and learning interest (0.63 and 0.51). These findings indicate that the AR-e-IM3 integration successfully fosters engagement and meaningful learning, aligning with Generation Alpha’s digital learning preferences. This study underscores the potential of technology-enhanced affective–cognitive models in elementary mathematics education. The implications include the scalable adoption of such media to strengthen 21st-century competencies—particularly critical thinking, spatial reasoning, and intrinsic motivation—while supporting curriculum innovation in resource-constrained settings.
