    Abstract

    In particular, Indonesian students enroll their first algebra class in secondary school. Generally speaking, most of the Indonesian classes will start with a very formal algebraic lesson which diminish the chance for the students to do an investigation to generalize an algebraic pattern. In one hand, generalization is the important aspect of algebra which distinguish it from its ancestor: arithmetic. This tendency leads to a number of obstacles encountered by the students in learning algebra (see Jupri, Drijvers & van den Heuvel-Panhuizen, 2014). Reflect to the global view of difficulties in learning algebra, the current research is conducted.The present study is aimed to design a local instructional theory which helps the students to build their sense of structure with the support of visualization to develop their generalization ability. Reflect to the aim of this study, design research is chosen as the appropriate approach. In addition, Pendidikan Matematika Realistik Indonesia (PMRI) which is adapted from Realistic Mathematics Education (RME), is applied as the guideline when designing the series of learning activity. The subject of the study are four fifth grade students of MIN 2 Palembang who are following fifth lessons of the pattern investigation activities. The data showed that the students were able to reveal the general structure of a pattern by the support of visualization. The sense of structure gives an opportunity for the students to do generalization based on their point of view toward the regularities on the pattern. Keywords: algebra, structure, sense, generalization, PMRI, RME, design
