The Indonesian Realistic Mathematics Education (IRME) approach, when contextualized within the Bukit Sulap tourism area, offers a promising solution to this challenge. This study aims to design a learning trajectory for teaching the surface area of polyhedron using IRME in the context of Bukit Sulap tourism. Employing a research design with a validation study type, the study was conducted in three phases: preparation and design, experimental teaching, and retrospective analysis. The participants were 27 elementary school students from Lubuklinggau City, Indonesia. Data collection instruments included surface area problem-solving worksheets, video recordings of in-depth learning interviews, field notes, and observation sheets. The findings suggest that the Bukit Sulap tourism context significantly enhanced students' understanding of surface area problems, specifically those involving combinations of cuboids and cubes. Additionally, IRME effectively facilitated students' comprehension of abstract mathematical concepts, particularly the surface area formulas for cubes and cuboids. The study concludes that using the Bukit Sulap tourism park context as a starting point for teaching the surface area of polyhedron aligns well with the principles of IRME.

Fraction learning has gained significant attention in mathematics education research, with a growing body of literature addressing the instructional challenges inherent in teaching fractions effectively. Establishing a solid conceptual foundation in fractions is critical to fostering broader mathematical proficiency, yet many students continue to struggle with core fractional concepts. This study addresses these issues by integrating a real-world context—Musi Rawas tourism—into fraction instruction, targeting pre-service elementary teachers enrolled in an elementary mathematics education program. Adopting a design research methodology, specifically a validation study, the study progresses through three structured phases: preliminary design, design experiments (encompassing pilot and teaching experiments), and retrospective analysis. Data collection involved teaching materials, observational checklists, and documentation to capture the instructional dynamics and learning outcomes. The study’s primary contribution is a localized instructional theory for teaching fractions within a tourism context, organized across five progressive learning activities: problem identification in the Gegas Water Lake tourism setting, contextual model development, model-based problem-solving, context-specific solution formulation, and abstraction of mathematical conclusions. This framework offers an innovative pedagogical approach, illustrating the potential for enhancing fraction learning through contextualized instruction in tourism, with detailed insights into the methodology and outcomes presented in the full study.

This research aims to describe students' cognitive processes in understanding fractions through a tourist context. This research method is design research. The data collection technique is through tests and in-depth interviews. The results of this research show that student's cognitive process in understanding fractions through a tourism context is that students first understand the problems in the tourism context of Lake Air Gegas; then students create mathematical models based on context; third, students complete mathematical models based on context; the fourth student creates a solution to the context problem; Finally, students make mathematical conclusions. Through the tourism context, students can solve problems appropriately. The conclusion is that there are five stages of students' cognitive process in discovering the principle of multiplication of fractions, namely students understand the problem through a tourism context, create a mathematical model based on context, complete a mathematical model based on context, create a context problem solution, and end by making mathematical conclusions about the principle of Multiplication of Fractions. Therefore, it is recommended that mathematics teachers use the tourism context as a starting point for mathematics learning.

The concept of surface area for flat shapes is often perceived as a challenging mathematical topic among elementary school students. In fact, the context of tourism can be integrated into the learning of geometry, for example, the topic of surface area. The objective of this study is to develop a learning trajectory that enhances problem-solving skills with respect to surface area problems in the context of Bukit Sulap, a tourism destination in Lubuklinggau City. The design research methodology, which included a validation study, was implemented in three stages: preparation and design, experimental teaching, and retrospective analysis. The subjects of this study were 27 elementary school students in Lubuklinggau City, Indonesia. The instruments utilized in this study included surface area problem solving task sheets, video recordings of in-depth interviews conducted during the learning process, field notes, and observation sheets. The findings of the study indicate that learning trajectories designed within the context of Bukit Sulap facilitate students' comprehension of problems, formulation of problem-solving strategies, implementation of these strategies, and interpretation of the results of problem-solving processes. The activities included in the learning trajectory are as follows: defining the contextual problem; self-review; designing a resolution plan; implementing the resolution plan; and establishing a mathematical model regarding surface area within the context used. Through the use of tourism as a context, students are expected to be able to solve surface area problems and learn the principles of surface area of flat shapes. This learning approach is an effective technique for improving problem-solving skills regarding surface area.
