TEACHING AND LEARNING MULTIPLICATION OF MULTI-DIGIT NUMBERS IN REALISTIC MATHEMATICS EDUCATION (RME)

This study developed a learning trajectory of the multiplication of multidigit numbers in Indonesian primary schools using Realistic Mathematics Education (RME). It was the third cyclic process of the developmental research process conducted in 4 primary schools in Medan and Yogyakarta in the academic year of 2000. This study produced a local instruction theory of teaching multiplication of multidigit numbers in primary schools in Indonesia. The learning trajectory was begun by introducing the repeated addition of ten numbers, the multiolications by 10, the multiplication by multiples of the, and the standard multiplication algorithm. This local basic learning trajectory theory of multiplication was opened for adjusment and justification and it functioned as guidance for other research in conducting the next development research.
