Abstract

Many recent studies found that students tended to have difficulty in grasping the concept of fraction. In order to overcome all the difficulties, this study presents a sequence of classroom activities aimed at constructing the understanding of fraction. This study enables prospective teachers as students to work with contextual situations. Realistic Mathematics Education (RME) underlies the design of the context and the activities. The aim of the research contributes to practical domains especially in mathematics learning using Realistic Mathematics Education. Design research was chosen as an appropriate means to achieve the aim. It was conducted in three phases, preliminary design, teaching experiment (first and second cycles), and retrospective analysis. This study involved two classes of prospective teachers (first cycle); some prospective teachers were analyzed in detail which was held at STKIP Garut. The result of this study showed that a sequence of activities could bring prospective teachers' learning from the contextual situation to more formal situation and give them the way of idea in teaching it. They could do every contextual problem with their reasoning. This result was supported by a sequence of classroom activities that have been given. It could be seen from comparing pre-test and post-test, prospective teachers' work increased and many strategies with reasoning were come up in the end of learning. Learning trajectory on this study could be used for school learning.
