Analysis of the Epistemological Obstacle of Junior High School Students on Proportion Topic

Abstract

This research is motivated by most of students who have difficulty solving math problems, especially in proportion topic. Considering the importance of overcoming learning obstacle experienced by students, knowledge is needed by teachers to know obstacles students expenence in solving math problems. The purpose of this research is to find out what are the epistemological obstacles of the students in solving proportion problems The descnptive qualitative research method was used in this research. The subjects of this research were students of grade eight SMP Al-Halim Garut with a total of 29 students. Researchers are the main instrument that plays a role in the entire process of research activities, from determining the focus of research, collecting data, analyzing data to making conclusions or verification. Data were collected using test instruments and interview techniques. Based on the results of the discussion above regarding the epistemological obstacles experienced by students on the topic of proportion, there are several epistemological obstacles including obstacles to understanding concepts, obstacles to using problem solving procedures, and obstacles to problem solving operational techniques.
