The Learning Trajectory of Social Arithmetic using an Indonesian Traditional Game

Abstract

The aim of this study is to design mathematics learning trajectory in social arithmetic using an Indonesian traditional game called the Kubuk Manuk. This game was used as the starting point in the learning process by applying the Indonesian Realistic Mathematics Education approach. A design research method was applied in the three stages, namely the preliminary design, the design experiment, and the retrospective analysis. The results of this study indicates that in the learning of social arithmetic, the learning trajectory can be practiced using local contexts such as culture or other things easily found in the daily activities of the students. With the use of the Kubuk Manuk Indonesian traditional game, it helped to stimulate the students to understand their knowledge of social arithmetic concept. Additionally, the stages in the learning trajectory have important roles in understanding the mathematics concepts of expenditure, income, profits and loss within the trading activities.
