Abstract

Background: Problem-solving ability and mathematical disposition are essential skills in mathematics education, particularly in developing critical thinking and practical application among students. Model-Eliciting Activities (MEAs) have been introduced as an instructional approach aimed at enhancing these skills by integrating real-world problems into learning. However, the effectiveness of MEAs in establishing a significant relationship between problem-solving ability and mathematical disposition remains unclear, necessitating further investigation.Aim: This study aims to analyze the association between problem-solving ability and mathematical disposition after implementing Model-Eliciting Activities (MEAs) in instruction.Method: This study employed a quantitative design with a cross-sectional approach, involving 30 fifth-grade students from SDN 02 Bojongsari, Depok, Indonesia, as participants. Data were collected using a problem-solving ability test and a mathematical disposition questionnaire. Subsequently, the data analysis was carried out using chi-square tests.Result: The results of the study showed that the χ2 value of 0.731 is less than α = 0.947, indicating that there is no significant relationship between mathematical problem-solving ability and mathematical disposition.Conclusion: The study concluded that no association was found between problem-solving ability and mathematical disposition among elementary school students after implementing MEAs in instruction. Additionally, although there is a tendency for students with a high mathematical disposition to demonstrate stronger problem-solving skills, this correlation is not strong enough to be considered significant

Abstract

Effective evaluation of student performance is crucial. Hence, many kinds of techniques are used such as statistics, physical examination and currently data mining techniques to evaluate student performance. Data mining techniques as known as Educational Data Mining (EDM) collect, process, report and used to find the unseen patterns in the student dataset. EDM uses machine learning techniques to dig out useful data from multiple levels of meaningful hierarchy. Various data from intelligent computer tutors, classic computer based educational systems, online classes, academic data in educational institution, and standar assesment can be process for EDM. This led universities include open and distance learning (ODL) to collect large volume of student and learning data in their learning management systems (LMS). Students in ODL are relatively familiar with LMS and many learning activities such as number of accessing materials, student participation in discussion forum recorded in LMS. The processes of using EDM to improve the quality of educational policy maker with data-based models have become a challange that institutions of higher education face today. Therefore, this study aims to design applications that predict student performance in online learning using machine learning techniques based on EDM. The machine learning technique used in this research is Fuzzy-KNN. Testing using Fuzzy-KNN produces an accuracy of 92.5%.

Abstract

This study investigates the effectiveness of the Problem-Based Learning (PBL) model in fostering students’ learning independence and mathematical creative thinking skills. The research was conducted with seventh-grade students at SMP Negeri 2 Mesuji, Lampung, during the odd semester of the 2024/2025 academic year. The population comprised 216 students across seven classes, from which two classes were selected using cluster random sampling. A pretest–posttest control group design was employed. Data were collected through essay tests on the topic of social arithmetic and questionnaires assessing students’ learning independence. The data were analyzed using t-tests, N-Gain analysis, and one-proportion z-tests. The results indicate that the PBL model was more effective than conventional learning in enhancing both mathematical creative thinking and learning independence. The experimental group achieved a significantly higher average N-Gain score than the control group. Furthermore, over 60% of students in the experimental class attained a “good” category in learning independence after the intervention. Improvements in creative thinking indicators—fluency, flexibility, originality, and elaboration—were also more pronounced in the PBL group. These findings demonstrate that Problem-Based Learning not only improves students’ cognitive abilities but also cultivates essential learning dispositions such as independence and creativity. This research provides empirical support for the integration of student-centered learning models in mathematics education to promote higher-order thinking skills.

Abstract

This study aims to develop a Desmos-assisted module and implement it through Problem-Based Learning (PBM) to improve the mathematical communication and representation skills of ninth-grade students. The research employed the ADDIE development model, which includes the stages of Analysis, Design, Development, Implementation, and Evaluation. Validation by three experts resulted in an average validity score of 90.42%, indicating that the module is highly valid. Student response questionnaires yielded an average score of 4.03 out of 5, suggesting that the module is practical to use. Student improvement was measured through pretests and posttests. The average pretest scores for communication and representation skills were 66.93 and 63.41, respectively, which increased to 92.39 and 90.72 in the posttest. The N-Gain score of 0.78 indicates a high level of improvement. These results show that using the Desmos-assisted module in PBM is effective in enhancing students’ mathematical communication and representation skills. Therefore, the developed module is feasible for use in mathematics learning at the ninth-grade level.

Abstract

Background: Although three-dimensional (3D) geometry is an essential component of the elementary school mathematics curriculum, research exploring how students develop spatial understanding of 3D geometric objects in authentic learning contexts remains limited. Furthermore, the challenge of bridging visual, verbal, and manipulative representations persists as a major gap in the literature.Aims: This study aims to address this gap by examining the process through which elementary students develop conceptual understanding of 3D geometry using a grounded theory approach.Method: The study was conducted at a public elementary school in Indramayu Regency, West Java, Indonesia. A total of 26 students (20 female and 6 male, aged 11–12) voluntarily participated. Data were collected through 3D geometric visualization tests and in-depth interviews focusing on students' thought processes in imagining, comparing, and manipulating spatial forms. Data analysis followed the three stages of grounded theory methodology: open coding, axial coding, and selective coding, to construct a theory grounded in empirical data.Results: The findings reveal that students’ understanding of 3D volume is still in a transitional stage, moving from concrete experiences to formal mathematical representations. Familiar local contexts alone were found insufficient to bridge spatial understanding without adequate visual and pedagogical support. Major obstacles included conceptual misconceptions, procedural errors, limited visualization skills, and reliance on teacher assistance.Conclusion: The core category, “multiple representations as a bridge to spatial understanding,” underscores the importance of integrating concrete visualization, verbal description, and mathematical symbolism in geometry instruction. This study suggests that teachers should design instructional strategies that systematically combine visual media, concrete manipulatives, and verbal approaches. Such integration is crucial to ensure that local contexts effectively serve as a bridge between real-world experiences and abstract mathematical understanding.
