Abstract

Mathematical modelling ability is the ability to convert real problems into mathematical models, then perform mathematical processes on the model and interpret mathematical results into real-world situations again. Students' mathematical modelling ability can be supported by a learning process that actively involves students and is able to bring students closer to learning resources in the real world. Outdoor learning with mobile math trails is designed to support students' mathematical modelling activities in the learning process. The aim of this study is to describe how outdoor learning with mobile math trails can support students' mathematical modelling ability, and to find out the improvement of students' mathematical modelling ability after the implementation of outdoor learning with mobile math trails. This study is a type of design research. This study uses design research as the research method with three phases, namely preparation and design, teaching experiment, and retrospective analysis. This study was conducted at SMP Negeri 19 Semarang involving 32 eighth-grade students. The Hypothetical Learning Trajectory (HLT) was designed and learning activities that include several math trails tasks were created, then students run the activity. Data were gathered by observation, interviews, tests, and worksheets. The findings indicate that outdoor learning with mobile math trails that has been implemented can support students’ mathematical modelling abilities. The learning activities can provide opportunities for students to engage in meaningful mathematical modelling activities in accordance with mathematical modelling indicators. The study identified a link between HLT as learning design and mathematical modelling activities in learning implementation. Based on the analysis of the results of the pre-test and post-test, it was found that students' mathematical modelling abilities had increased in medium category. The learning design can be implemented by teachers and the Hypothetical Learning Trajectory (HLT) can be used as a reference for developing other learning tools. In addition, this research is still limited to the modeling ability and polyhedra material. Further studies are essential for project development and implementation in other location with different situations and aspects of study.
