Abstract

Problem posing is a learning approach that trains students to be able to process and communicate mathematical problems based on information obtained. This study aims to describe the ability of high school students to pose problems on the topic of the system of linear equations in two variables (SLETV). This study used a quantitative descriptive study involving 60 high school students in the East Surabaya area. The results showed that students were able to submit 60 problems where consists of 54 problems can be categorized and 6 problems could not be categorized. Based on the semantic structure of mathematics, there were about 17 students (31,48%) which is able to pose problems using 1relationship. Moreover, as many as 13 students (24,07%) were able to pose problems using 2relationships. Besides that, 13 students (24,07%) were able to propose problems using 3-relationships while the remaining 11 students (20,37%) able to pose problems using 4-relationships. Based on the language structure (syntax), about 23 students (42,59%) were able to pose problems using assignment propositions. Furthermore, as many as 17 students (31,48%) were able to pose SLETV problems using relationship propositions while the remaining 14 students (25,93%) were able to pose a problem using a presupposition proposition. Thus, it can be concluded that based semantic structure, students more easily posed problems one relationship. But, based on language structure (syntax), most students are able to pose problems using the proposition of proposition.
