Learning Fractions through Swimming Context for Elementary School Students

This research aimed to produce learning trajectory by using the swimming context in helping students to understand the concept of fractions and addition of fractions. The approach used was Realistic Mathematics Education, Indonesian version (PMRI). The study involved 6 fourth grade students with heterogeneous capabilities in Elementary School IBA, South Sumatra, Indonesia. The method used was a design research with three phases of the preliminary design, the design experiment, and retrospective analysis. However, this study only shows the results at the phase of the design experiment, in particular on a pilot experiment. Data collection techniques used were video recordings, photograph, the student's work, the results of pretest and posttest, and student interview during learning. The results showed that the swimming context could stimulate students' informal knowledge of the meaning of fractions in which it can eventually be used in addition of fractions material.
