Studi ini melibatkan 60 calon guru matematika dari Universitas Sriwijaya. Pengumpulan data dilakukan melalui wawancara, observasi, dan lembar kerja. LT yang dikembangkan terdiri dari empat langkah utama yaitu memahami jenis data, menerapkan konsep statistik, menganalisis tren probabilitas, dan menggunakan model statistik untuk prediksi. Studi ini menekankan pentingnya menghubungkan konsep teoretis dengan aplikasi praktis, memberikan wawasan berharga bagi pendidikan calon guru dan pengembangan kurikulum. Abstract Statistical literacy is essential for prospective teachers to interpret data accurately and make informed decisions. However, many struggle due to abstract instructional approaches. This study develops a Learning Trajectory (LT) that integrates Pagar Alam coffee production as a real-world context to support statistical literacy of prospective teachers. Employing a design research methodology within a validation study framework, the research consists of three phases: (1) a preliminary phase, (2) a design experiment phase, including a pilot experiment and a teaching experiment, and (3) a retrospective analysis phase. The study involved 60 prospective mathematics teachers from Sriwijaya University. Data collection methods included interviews, observations, and worksheets. The developed LT comprises four key steps: understanding data types, applying statistical concepts, analyzing probability trends, and using statistical models for predictions. This study underscores the importance of linking theoretical concepts with practical applications, providing valuable insights for teacher education and curriculum development.

Statistical literacy has emerged as a central competence in mathematics education, particularly for prospective teachers who must be able to interpret, analyze, and critically evaluate data in a world increasingly shaped by information and statistics. However, previous research shows that many prospective teachers continue to struggle with developing statistical literacy, especially in connecting abstract concepts to meaningful contexts. This gap highlights the need for instructional designs that not only strengthen statistical reasoning but also draw on culturally embedded practices to enhance relevance and engagement. Addressing this challenge, the present study develops a Local Instructional Theory (LIT) that supports prospective teachers’ statistical literacy through the integration of local cultural contexts in South Sumatra, designed within the framework of Realistic Mathematics Education (RME) as adapted in Indonesia, namely Pendidikan Matematika Realistik Indonesia (PMRI). Employing a design research methodology, the study was conducted in three phases: a preliminary investigation, a design experiment (pilot and teaching experiment), and a retrospective analysis. The resulting LIT was structured around three context-based learning trajectories, each targeting a key dimension of statistical literacy: data visualization, data interpretation, and critical evaluation. Instructional activities were grounded in authentic cultural contexts—such as Pempek demand during Ramadan, the Bekarang Iwak fishing tradition, and coffee productivity in Pagar Alam—which were used to bridge statistical concepts with learners lived experiences. Findings from the teaching experiments indicate that prospective teachers demonstrated notable shifts from procedural to conceptual reasoning and from descriptive analysis to reflective critique. Participants also showed improved ability to select appropriate graphical representations, interpret contextual data, and critically assess the credibility and sufficiency of statistical information. These outcomes underscore the potential of culturally relevant instructional design to foster holistic statistical literacy. The study contributes both theoretically and practically by offering a validated model for integrating cultural contexts into mathematics education, thereby enriching prospective teachers’ curriculum and providing a replicable approach for diverse educational settings.

This study aims to support students proportional reasoning in comparison problems using Palembang culture as context and PMRI approached. Six students of 7th grade were participated. We used design research as research approach, a Hypothetical Learning Trajectory (HLT) was develop and a set of activities using Palembang culture as context, such as ketek fare, empek-empek price, lempok price. Theoretical development is driven by an iterative process of designing instructional activities, performing teaching experiments and conducting retrospective analysis in order to contribute to Local Instruction Theory (LIT) to support students proportional reasoning in comparison problem. Data collected by making video recording about actual teaching and learning in classroom, collecting students worksheet, giving pretest and posttest, interviewing students. The designed HLT compared Actual Learning Trajectory (ALT) during pilot experiment to analyze whether the students learned or did not learn from what we had designed in the instructional sequence. Retrospective analysis of pilot experiment showed that by using Palembang culture as context can support students proportional reasoning in middle school to solve comparison problems.

This research was a qualitative descriptive study to analyze the misunderstanding of students' concepts in solving two fold integral problems on polar coordinates. The 30 students who took the multivariable calculus course became the subjects in this study. Data were collected using tests and documentation. The results of the student's test answers and the documentation of students answers were corrected, analyzed based on indicators of conceptual understanding and data displayed. Analysis of students' answer errors based on indicators of concept understanding, namely (1) restating the integral concept. (2) representing the concept in other forms, (3) selecting and using procedures and (4) using problem solving concepts and algorithms. In restating the integral concept, students directly use the upper and lower limits of integration without writing down the integration results first. The mistake of representing the function to the graph is that the function is immediately sketched without creating a table, plotting points and creating curves. Errors in selecting and using procedures and using problem solving algorithms are due to students' lack of prior knowledge of prerequisite materials, namely trigonometric integrals and trigonometric functions.

Statistical literacy was one of the important abilities that must be possessed by prospective mathematics teachers in the era of society 5.0. This research was qualitative descriptive to develop statistical literacy questions for prospective mathematics teachers using indicators of the five bases of statistical literacy and PMRI principles. The questions were developed using a design research type of development study to see the validity and practicality of the questions. The research stages included the preliminary stage, and the prototyping stage (self-evaluation, expert review, one-to-one, and small group). As many as 13 prospective mathematics teachers participated in this study, in the one-to-one stage and the small group stage. Data were collected through walkthroughs, observations, interviews, and video recordings. Data were analyzed qualitatively to describe the results of each stage. The results showed that the statistical literacy questions developed were valid and practical. Validity was shown from the expert review stage which validates the content, construct and language aspects used in the questions. Practicality can be seen from the one-to-one and small group stages where students can work on the questions given. Further research was needed using more subjects to see the potential effects that emerge from this study.
