Analysis of the Problem Solving Ability of Mathematics Education Students Using the Trigonometry Module

Abstract

This study aims to analyze students problem-solving abilities in the mathematics education study program after learning using modules in the trigonometry course. This research is a qualitative descriptive study. The subjects in this study were students of mathematics education semester I of low, medium, and high ability. The data collection technique is a test using problem-solving questions, interviews, and documentation. The data analysis technique used document analysis techniques. Data analysis was carried out by collecting data, reducing data, presenting data, and finally drawing conclusions and verifying data. The result of this research is that the subject can understand the problem by identifying the information that appears on the issue and determining the method or formula used in solving the problem. After that, solve the trigonometric problems given and check the results of the answers that have been done. The trigonometric material provided in the problem-solving ability test is the size of the angle, trigonometry ratio, and trigonometric identity. Students still have difficulty completing proving trigonometric identities because students are still confused and also experienced misconceptions in trigonometric and algebraic properties to confirm this trigonometric identity.
