    Abstract

    One of causes of difficulties that students often encountered when working with problems of linear equations is their inflexibility in employing strategies to solve for an equation. As a consequence, the students might be able to solve a problem easily, but often fail to solve another similar problem. Focusing on this phenomenon, the present study aims to provide a series of lessons that build students’ flexibilities in employing strategies to solve linear equation problems. The study is a design research, which is a preliminary to a larger study. This study is implemented to a small group consisting of four 7th graders of SMP Pusri Palembang. Balancing is chosen as an approach to base the overall design and the promoted solving strategy. This study first revealed a trend of students’ strategies, that is, either unsystematic guess-and-check or (a not meaningful) formal problem solving, that the students used all the time when solving any linear equation problems. During the learning implementation, the students’ strategy started to vary. The balancing activities have helped students to make sense of equalities. The balance was then improving to be a model that helps students perform transformation strategy, which is a more meaningful formal strategy to solve for equations. This shows the applicability of the proposed design to deal with students’ rigidity in solving linear equation problems. Keywords: Strategies, linear equations, design research, balancing
