Abstract
Research on learning obstacles can provide an description of the conditions in the learning process that experience certain obstacles in achieving learning outcomes. This research aims to produce a description of the learning obstacles experienced by students in solving system of linear equations in two variables problems related to ability mathematical communication. This research used a qualitative research method . The research subject were 30 students of eighth grade students in class in one junior high school in Padangsidimpuan, North Sumatera. The results showed that most students experienced learning obstacles that were ontogenic, didactic, and epistemological in solving system of linear equations in two variables related to mathematical communication abilities, based on the identification of mathematical communication abilities and the problems experienced by students in solving system of linear equations in two variables problems. Based on this, this research has identified that there are learning obstacles for students in solving solving system of linear equations in two variables problems based on the results of the instrument tests, interviews and document analysis by researchers.
Keywords: learning obstacle, system of linear equations in two variables, mathematical communication ability
