This research aim is to know the students' understanding in adding number up to 20 using traditional game of dakocan and to acquire learning trajectory of adding number up to 20 using traditional game of dakocan for the first grade of primary school. This research used methodology of design research that consists of three phases, there are preliminary design, teaching experiment, and retrospective analysis. Subject of this study is 33 first grade students of Sekolah Dasar Negeri (SDN) 98 Palembang as one of partners' school of Pendidikan Matematika Realistik Indonesia (PMRI). The result of this research shows that the students' understanding in adding number up to 20 can be stimulated by using traditional game of dakocan as a context. All of strategies and model that is used by students and also their result discussion shows how construction and contribution of students can help them to understand concept of adding number up to 20. All the activities that are done by students produce learning trajectory to gain the goal of learning. Each steps of learning trajectory of students has an important role in understanding the concept from informal to the formal level. Learning trajectory using dakocan that is produced consist of playing dakocan, put the model of dakocan to the frame ten dakomatika to understand the relation of part and whole of ten combination in adding number, and solving contextual problem in adding number up to 20.

The objective of this study was to investigate the role of the context to enable the students to understand the concept of volume of a sphere in class VIII. The context of this research was using a watermelon as teaching aids by using PMRI approach. The method used in this study was design research; the stages were preleminary design, teaching experiment, and retrospective analysis. The results of this study indicated that the role of watermelon as teaching aids supported the students to develop their knowledge about the concept of volume of a sphere, and enhance their understanding about the material so that the learnin becomes more meaningful. In giving the volume of a sphere its better not to be taught the students by giving formula directly, however they were given the opportunity to understand the volume of a sphere with their own concept in real situation. The existence of such a situation, the student will be easier to learn the material volume of a sphere at a higher level.
