ANALISIS KEMAMPUAN PEMAHAMAN KONSEP MATEMATIKA PADA MAHASISWA DALAM MENYELESAIKAN SOAL MATERI LIMIT FUNGSI

Abstract

This study aims to determine the ability to understand mathematical concepts in students in solving Limit Function material problems. The research method used in this research is descriptive qualitative method. Subjects were selected based on the UAS scores for the differential calculus course and also with the consideration of the lecturer in charge of the course. The research subjects were 3 students, each of whom had high, medium and low abilities. Data collection in this study used literature study, tests, interviews and documentation. Data analysis techniques in this study are data reduction, data presentation, and conclusion drawing. Then the data were analyzed descriptively qualitatively based on indicators of concept understanding, namely (1) restate a concept, (2) classify objects according to certain properties, and (3) use, utilize and select certain procedures. Based on the results of the research that has been carried out, it can be concluded that: subjects with high abilities are able to fulfill indicators (2) and (3), subjects with medium abilities are able to fulfill indicators (3), and subjects with low abilities are not able to fulfill the three indicators. The findings in this study showed that the three subjects were equally unable to fulfill the indicators of restating a concept where the three subjects were unable to interpret the graph according to what was intended in the question.
