    Abstract

    Nowadays, the way of teachers in teaching proportion usually stands at giving the students a ready-made formula, such as cross multiplication, to solve proportional problems involving fractions. As a result, the students tend to memorize the formula and just apply it in solving the problems. This will be meaningless for them because they do not even know and do not understand the meaning of proportionality. Additionally, this will make students difficult to develop their proportional reasoning. Therefore, there is a need for us to support the students to learn about proportion and to develop their proportional reasoning to solve problems through innovations in teaching proportion. To deal with this situation, design research was chosen as the research approach of this study. It highlights a new way for fifth grade students in primary education to learn about proportion which includes fractions. Additionally, it underlies an innovative way for mathematics teachers to teach proportion since this study also employs the heuristic of Realistic Mathematics Education (RME) as the main theory in which we designed five instructional activities within a learning trajectory. Consequently, the aim of this study was to investigate how we can support students to learn about proportion and to develop their proportional reasoning. In conducting this study, 6 fifth-grade students from SD Al – Hikmah were involved. Thus, the students’ activities during the teaching and learning process were recorded so that they can be analyzed. The retrospective analysis of the teaching and learning process showed that models, such as: students’ visualization, can support students to learn about proportion and to develop their proportional reasoning
