Description of Student's Misconceptions on Trigonometry Based on Problem-Solving Ability

Abstract

This research aims to describe some misconceptions by students based on students problem-solving abilities. This research was conducted at MAN 2 Palopo in the 2019/2020 school year. The type is descriptive research with a qualitative approach. The collection technique used is a problem-solving ability test consisting of 3 trigonometric questions and interview guidelines. The sampling technique was carried out by using purposive sampling based on the types of misconceptions. The subjects in this study are 6 students, with 2 students with high abilities, 2 students with moderate abilities, and 2 with low abilities. The data analysis technique includes 3 stages: data reduction, data presentation, and conclusions. To check the validity of the research data, the researcher used the triangulation technique. Subjects with high mathematical problem-solving skills did not experience misconceptions, subjects with mathematical problem-solving abilities experienced classification and theoretical misconceptions, and subjects with low mathematical problem-solving abilities experienced theoretical and correlation misconceptions.
