Abstract: In the late 70's, in reaction to both "New Math" movement in the United States and "mechanistic mathematics education" approach to mathematics education in Netherland, Realistic Mathematics Education (RME) has been introduced by Freudenthal and his colleagues. In this educational approach, Freudenthal considered mathematics as a human activity. Based on this approach, education should give students the opportunity to re-invent mathematics by doing appropriate activities. Recently, the National curriculum of Islamic Republic of Iran has been developed by the Ministry of Education to provide educational policies. In this document, an implicit emphasis on so called “realistic” aspect of the program can be seen in the mathematics curriculum framework section. In this paper, I first, introduce the different aspects of RME, and then this educational approach has been traced in the newly written mathematics textbooks in Iran.
