Abstract

Self-regulated learning (SLR) is a condition in which students actively participate in the process of acquiring knowledge, and it closely relates to students’ metacognitive, motivational, and behavioral aspects. In order to measure this variable, an instrument was developed by referring to the Zimmerman cycle in the form of a questionnaire. Therefore, this study aims to analyze the construct validity of SLR questionnaires designed for high school students through Rasch model analysis. The method employed was descriptive quantitative research. The analyzed questionnaire consists of 50 positive statements, rated on 4-point Likert scale, and arranged of forethought, performance, and self-reflection phases. Furthermore, the construct validity was conducted on 235 third grade (XII) high school students in Gunungsitoli City (Indonesia), with a gender distribution of 58.29% female and 41.70% male. The results showed that the questionnaire with 4-rating scales satisfied the criteria for validity, gender inclusiveness, and unidimensionality based on Rasch model analysis for 25 statements. The implication of this research shows that the SLR questionnaire developed is valid and can be used in wider field research, especially in mathematics learning.

Abstract

In the context of globalization, traditional cultural values are increasingly at risk of being overlooked in modern education. The Alang Tulung tradition of the Gayo people in Aceh, which promotes gotong royong (mutual cooperation), social responsibility, and collaboration, offers meaningful values for character development in youth. This study investigates the integration of Alang Tulung into a Blended Project-Based Learning (BPjBL) model. A qualitative approach was employed, utilizing semi-structured interviews, classroom observations, learning outcome evaluations, and student surveys. The study aimed to assess both the cultural significance and educational effectiveness of the Alang Tulung-based BPjBL model. The findings indicate that incorporating Alang Tulung values into BPjBL enriched students’ learning experiences and supported cultural preservation. Academic performance improved significantly, with an N-Gain score of 0.72. Collaboration skills also increased, with an average score of 4.6 and 92% of students displaying optimal teamwork. Additionally, 90% of participants reported a deeper understanding of the Alang Tulung tradition, and 88% recognized its relevance to contemporary education. While the model proved effective, challenges such as limited internet connectivity and the absence of structured cultural learning modules were noted. These barriers suggest the need for infrastructure improvements and curriculum development. The integration of local cultural traditions like Alang Tulung into educational models can enhance student engagement, foster character development, and contribute to cultural preservation amidst globalization.

Abstract

Numeracy literacy is an essential competency that should be developed from the elementary school level to help students understand and apply mathematical concepts in daily life. However, elementary school students’ numeracy literacy remains low, especially in understanding problems, connecting numerical information, and solving contextual mathematical tasks. This condition is caused by mathematics learning that is still abstract, procedural, and less connected to students’ real-life experiences. Therefore, contextual and engaging learning media are needed to support numeracy learning. This study aims to develop a Doodle Art comic based on Realistic Mathematics Education (RME) to enhance elementary school students’ numeracy literacy. The study employed a Research and Development (R&D) method using the ADDIE model, which includes analysis, design, development, implementation, and evaluation stages. The research instruments included validation sheets, teacher and student questionnaires, numeracy literacy tests, observations, and interviews. The results showed that the RME-based Doodle Art comic was categorized as highly feasible, with an average validation score of 4.41. Teacher responses obtained an average score of 4.54, categorized as very practical, while student responses obtained an average score of 4.50, categorized as very good. In addition, students’ numeracy literacy scores increased from 61.10 in the pretest to 76.18 in the posttest. The study concludes that the RME-based Doodle Art comic has the potential to become an innovative and contextual learning medium for improving elementary school students’ numeracy literacy.

Abstract

Background: Students in higher education consistently demonstrate significant difficulties in integral calculus, particularly in selecting appropriate problem-solving strategies and executing procedural steps. Despite extensive research on mathematical errors, studies integrating Newman Error Analysis (NEA) with technology-enhanced, project-based pedagogy at the university level remain scarce. Objective: This research aims to examine the types of errors students make in solving integral problems in calculus by implementing Project-Based Learning (PBL) using GeoGebra software. Methods: The research adopted a descriptive qualitative method with 15 ACT students from the Informatics Department of Universitas Pelita Harapan Medan. Data were collected from written integral test items, observation sheets, and brief interviews with selected students. Errors made by students were classified according to the Newman Error Analysis (NEA) framework, which consists of reading, comprehension, transformation, process skill, and encoding errors. Results: The findings suggest that the combination of PBL with GeoGebra enables students to visualize integral concepts dynamically and enhances their geometric understanding of both definite and indefinite integrals. The most frequent error was transformation (60%), followed by process skill (53.3%), comprehension (46.7%), reading (20%), and encoding errors (13.3%). These results indicate that many students continue to struggle with deciding how to integrate an expression and completing the correct computations. The method helped alleviate conceptual difficulties owing to the visualization features of GeoGebra. Conclusion: GeoGebra-assisted PBL effectively supports error diagnosis and conceptual remediation in integral calculus. Integrating dynamic visualization with project-based inquiry reduces transformation and process skill errors by helping students connect symbolic procedures to geometric interpretations.

Abstract

Mathematical literacy is a crucial competency for university students, yet research indicates that many students struggle to apply it effectively. This study aims to analyze students' mathematical mindsets in addressing mathematical literacy challenges and their implications for mathematics education in higher education. The research employs a descriptive qualitative design, involving three second-semester students selected through purposive sampling. Data collection methods include observation, in-depth interviews, and analysis of mathematical literacy tests, focusing on indicators such as the ability to formulate mathematical situations, apply mathematical concepts and procedures, and interpret mathematical results. Data analysis was conducted through several stages: data reduction, data presentation, drawing conclusions, identifying students' mindsets in solving mathematical problems, and source triangulation. The findings reveal that students' mathematical thinking is influenced by cognitive development, cognitive style, and problem-solving strategies. While some students successfully solve mathematical literacy problems, they still make errors in several concepts and often exhibit carelessness in reading the questions. This research has significant implications for mathematics education in higher education, including the need to emphasize conceptual understanding, balance procedures, and concepts, and utilize visual representations. The development of teaching materials and mathematical literacy questions should be designed to accommodate diverse student mindsets and be grounded in realistic contexts.
