Design research on plane figure learning by using picture story and pairing game to improve mathematical communication skills of second grade of primary school students

Abstract

This research aims to produce the learning trajectory to improve mathematical communication skills of second grade students on the plane figure by using picture story and pairing game. It uses design research which consists of three stages: preliminary design, design experiment, and retrospective analysis. In the stage of preliminary design, researcher designed the Hypothetical Learning Trajectory (HLT). In the stage of design experiment, researcher then applied the HLT in teaching second grade students to improve mathematical communication skills from informal knowledge to formal knowledge through mathematics activities. The activities are picture story by using tangram context and pairing game. Finally, in the of retrospective analysis, the result of HLT application was analyzed to acquire the final result namely; Learning Trajectory (LT) of picture story and pairing game. Second grade students were involved as samples of this research. The data were collected through interview, observation, test, documentation, and field note. The data were analyzed through triangulation of data and interpretation cross. The result of this research is LT of the plane figure by using tangram context picture story and pairing game to improve mathematical communication skills of second grade students.
