Abstract

The essence of the independent curriculum and Pancasila student profile requires teachers to adapt teaching materials to the PISA framework and invite students to think critically. For this reason, this qualitative descriptive research aimed to describe students' critical thinking skills in solving mathematical PISA-like questions on the quantity content in the context of the Jakabaring Palembang tourism using the Indonesian Realistic Mathematics Education (PMRI in Bahasa) approach. This research involved 36 under-15 students of a junior high school in Palembang. Data from observations, tests, and interviews were collected and analyzed qualitatively to measure students' critical thinking skills. The results of this study indicated that the students' critical thinking ability belonged to the moderate category, with a total of 22 students in this category. The highest scoring critical thinking indicator was interpretation (86.1%), while the lowest was analysis (13.8%). The former was dominant in students because when learning using the PMRI approach, students could model problems into their interpretations. Solving PISA-like questions could train students to develop the interpretation indicator of critical thinking skills and at the same time introduce the Palembang Jakabaring tourism.

Abstract

Mathematical modeling is key in helping students connect abstract mathematics with real-life situations by transforming practical problems into mathematical forms, solving them analytically, and interpreting solutions in context. This study investigates junior high school students' mathematical modeling abilities in solving PISA tasks on Uncertainty and Data, analyzed through the OECD (2018) framework of formulating, employing, interpreting, and evaluating. Employing a descriptive qualitative approach, we collected data through written tests and follow-up interviews with seventh-grade students. Findings reveal that students show moderate ability in employing mathematical procedures (50.2%) but struggle with formulating problems (45.3%). Most critically, they demonstrate significant difficulties in interpreting (33.7%) and evaluating (28.5%) solutions within real-world contexts, impairing their ability to apply mathematics practically. Qualitative analysis of written tests and interviews shows that students often develop mental strategies but fail to articulate them in writing. These findings underscore the critical need to strengthen higher-order modeling skills in instructional practices, particularly interpretation, evaluation, and mathematical communication. The study reveals essential gaps between procedural competence and practical application, suggesting that curriculum reforms should emphasize problem-solving approaches to develop mathematical modeling abilities that meet PISA’s standards.

Abstract

The System of Linear Equations in Two Variables (SLETV) is one of the essential topics in mathematics that often presents challenges for students to understand. Interventions in the learning process can be made by designing a Hypothetical Learning Trajectory (HLT) based on Indonesian Realistic Mathematics Education (PMRI), integrating local context to enhance student understanding. This study aims to describe the design of an HLT for the SLETV topic using the context of Jakabaring tourism in Palembang, which is relevant to students' daily lives. The method used is design research, consisting of three stages: preliminary design, design experiment (pilot experiment and teaching experiment), and retrospective analysis. The subjects of this study are 30 eighth-grade students from SMPN 9 Palembang. Data were collected through observations, interviews, and documentation. The HLT was compared with the Local Instructional Theory (LIT) that emerged during the learning process. The study results show that using the Jakabaring tourism context can facilitate students in understanding the SLETV concepts, formulating mathematical models from contextual problems, and solving these problems systematically while also introducing the relevance of SLETV to real-life situations.
