Zetra Hainul Putra

Abstract


This paper aims to investigate characterize features of didactic contracts in realistic mathematics
education teaching practice in Indonesia in the case of a lesson on addition. We just focus on some
episodes of 26 first grade students and a female teacher from SDN 197 Palembang learning
combinations that make ten based on a Palembang traditional food, pempek, and tablets of
medicine. The result shows that some features such as formulation and validation appear during
the teaching and learning process. The students are able to produce combinations that make ten
individually and collectively, and also make agreement for those combinations. The teacher has an
important role to guide students to the process of institutionalized knowledge.
