Abstract

This study aims to determine the learning obstacles experienced by students in understanding the concept of lines in three dimensional material. The research method used is descriptive qualitative method. Identification of learning obstacles is carried out using praxeology which includes type of task, technique, technology, and theory based on the results of the analysis of student and teacher books as well as previous research. The results of the study show that the learning obstacles that occur in students are didactical obstacles and epistemological obstacles. The didactical obstacle identified is the lack of emphasis on alternative solutions that can be used to solve several types of problems. The identified epistemological obstacle is that the problems presented are focused on the cube which causes limited solutions.
