DEVELOPING A LOCAL INSTRUCTION THEORY FOR LEARNING COMBINATIONS

Abstract

This research aims at developing local instruction theory for learning combinations by using Realistic Mathematic Education (RME). The LIT flow developed in this study is to find an easy learning path to help students build basic concepts in combination material. To achieve the objectives of this study, researchers used design research. The Hypothetical Learning Trajectory (HLT) was developed from a series of activities to get a better understanding about combinations at Senior High School (SHS) students. Theoretical development is supported by interactive process in designing learning activities, conducting teaching experiment and conducting retrospective analysis to contribute to the development of LIT combinations. An understanding of combinations emerges and develops during classroom learning activities. Qualitative analysis of teaching experiments shows that by using LIT teaching materials that contain the characteristics of PMR, students can build basic concepts and develop their understanding about combination.
