Learning fraction through the context of Asian Games 2018

Abstract

In August 2018, Indonesia will host Asian Games in two cities namely Jakarta and Palembang. As the researchers stay in the city of Palembang, we use this event as the context for designing mathematics lesson materials. This paper shares the results of the design research method, which aims to developing Learning Trajectory for primary school students. Three phases of design research were used namely preparing for an experiment, teaching experiment, and finally retrospective analysis. As the result, this research produces Local Instructional Theory (LIT) on fraction through the contexts of Asian Games 2018 sports namely swimming, shot put, rowing, running, and hurdles. The swimming context could stimulate students’ informal knowledge about the meaning of fractions. By using shot-put context can assist students in learning the subtraction of fractions. Furthermore, running context can help students understand the division of fractions. Meanwhile, rowing context can help students understand addition and subtraction of fractions. Lastly, the context of hurdles can help students to realize their knowledge about the concept of multiplication of fractions with natural numbers. Therefore, this study contributes positively to the various parties on how to teach fractions using the contexts in the learning process of Indonesian Realistic Mathematics Education.
