Learning trajectory of modeling situation problems utilizing tables and diagrams for elementary school students

Abstract

This research investigated the learning obstacles found in algebra learning and utilized them in the development of learning trajectory on algebraic thinking. Students have experienced algebraic difficulties due to several obstacles. The efforts to overcome difficulties require appropriate learning stages. Learning stages are designed based on the analysis of learning difficulties called learning trajectories. Learning trajectories are composed of systematic topic about tables and diagrams for elementary schools. Problem modeling is represented through tables and diagrams from concrete to abstract levels. The process of analysis results in an alternative didactic situation that can overcome osbtacles in algebraic thinking. This study has used qualitative research with hermeneutics and phenomenology paradigms. The result of this research is a learning trajectory which is a part of the lesson design in algebraic thinking in the elementary level.
