Abstract
Probability is one of the subjects in learning mathematics in the ninth grade. Based on the results of preliminary tests conducted, students still get difficulties in restating a concept of probability, students still mistaken in giving examples and not examples of probability events, and the relationship between theoretical and empirical probability, and also students still have difficulty in exploring empirical probability. That is because learning done in school is less meaningful for students. Therefore, this study aims to develop learning probability through the Realistic Mathematics Education (RME) approach. This research using design research method which consists of three cyclic phases, such as though experiment, instruction experiment, and retrospective analysis. Data in this study was obtained from student worksheets, interview sheets, field notes sheets, Hypothesis Learning Trajectory (HLT), voice recordings, and pictures. Based on the results of a retrospective analysis, learning with the RME approach can develop students ability in understanding probability concept. Students can understand theoretical and empirical probability, comparing the chance of events, and understanding the frequency of expectations in empirical events. RME principles can support students’ thinking through the use of contexts, the use of the models, the use of student construction results, interactivity, and the intertwining of various learning strands.
