Abstract

This research is qualitative research with design research methods and a development research type aiming to produce valid and practical worksheets on relational and functional materials based on problem-based learning (PBL) to support students' conceptual understanding. The learning process is carried out in the classroom with learning activities, accompanied by a student's worksheet, which consists of 2 questions. The subjects of this study were students of class VIII 10 of SMP Negeri 8 Palembang, with 6 students as the focus of the research. There are 2 stages in this research, namely: (1) preliminary stage and (2) prototyping stage (formative evaluation), which is divided into 5 stages, namely (1) self-evaluation, (2) expert review, (3) one to one, (4) small group and (5) field test. This research was conducted based on the learning system in schools with data collection techniques, namely walkthroughs, tests, interviews, and questionnaires, to be collected and analyzed qualitatively to see the validity and practicality of the worksheet. The results of this study will show that the worksheet that has been made is valid, as seen from the results of the expert review and practical validation sheets obtained from the questionnaire results, with an average of 84.03%, which is included in the valid and practical categories. The developed worksheet also supports understanding PBL-based concepts (Problem-Based Learning) in solving problems given in relation and function material, which can be seen from the overall student test results.

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

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.

Abstract

Mathematical problem-solving ability among students remains low in conventional learning environments. The integration of Augmented Reality (AR) into the Indonesian Realistic Mathematics Education (PMRI) approach facilitates visualization of abstract concepts and promotes contextual learning. This study analyzes the effect of PMRI-based circle learning assisted by AR on students' problem-solving abilities. A quantitative approach was employed using a One Group Pretest pretest-posttest design with 35 eleventh-grade students from SMA Srijaya Negara Palembang. Data were collected through a mathematical problem-solving test based on Polya's four stages: understanding the problem, devising a plan, carrying out the plan, and looking back, administered before and after the intervention. The Shapiro–Wilk test indicated that the data were normally distributed (pretest = 0.084; posttest = 0.309, both > 0.05). Paired sample t-test analysis revealed a pretest mean score of 19.37 and a posttest mean score of 66.51, with a mean difference of 47.14. The t-test result (t = -23.053, Sig. (2-tailed) < 0.001) indicated a significant difference between pretest and posttest scores. These findings demonstrate that the PMRI-based learning design assisted by AR is effective in improving students' problem-solving abilities through contextual learning experiences and interactive visualization. The results suggest that integrating PMRI with Augmented Reality in circle learning represents an effective instructional innovation for enhancing students' problem-solving abilities.
