Abstract
Understanding and using equal sign with one variable is dependent on the concept of equality. This study report is a part of full study on how to support students? understanding of linear equation with one variable. The aimed of this research is to supporting 7th graders to understand the concept of linear equation with one variable Hence, a set of learning sequence which consist of five activities were designed. By using design research, a Hypothetical Learning Trajectory (HLT) and mathematical activities were developed to get better understanding 7th graders in linear equation with one variable. Pendidikan Matematika Realistik Indonesia (PMRI) approach was used in this study. Data were collected through video, students? work, pre-test, post-test, field note and interview. Data were analyzed by comparing Hypothetical Learning Trajectory (HLT) with the actually learning trajectory in teaching experiment. The result shows that some students can used to apply equal sign in linear equation with one variable. Retrospective analysis of teaching experiment confirm that comparing the area of two rectangle are able to support students? understanding of equal sign in linear equation with one variable. Keywords: Equal sign, area of rectangle, linear equation with one variable, PMRI, Local Instructional Theory.
