The development of an RME-based geometrycourse for Indonesian Primary schools

The aim of this study was to develop and implement a valid, practical, and effective RME-based geometry course for Indonesian primary schools using design research approach. The research activities were divided into three stages namely front-end analysis, prototyping stage, and assessment stage that were conducted in a four year period. The focus of the chapter is to present detail and rational regarding the three stages. The result of the study was a high quality RME-based geometry course for teaching geometry at grade 4 in Indonesian primary school consisted of teacher's guide and student book. In the products lies the local instructional theory for teaching geometry that was effective for improving pupils' understanding, reasoning, activity, creativity, and motivation.
