Abstract

This study aims to determine student errors and the causes of student errors in solving trigonometric identity problems in class XI MIA SMAK St. Dominic Tambolaka. The type of research used is qualitative descriptive. The subjects of the study were 18 class XI MIA students at SMAK St. Dominikus Tambolaka. Data collection techniques use written tests and interviews. The results showed the percentage of errors made by students in solving math problems related to trigonometric identity. The causes of student errors include rushing to read math problems, not having the ability to focus attention on learning, not mastering trigonometric identity material, not understanding the formula that should be used, not being careful in carrying out the calculation process, carelessly doing problems because of previous mistakes, and rushing in working on the solving process.

Abstract

This study aims to find out the difficulties of students in solving PLSV problems using the demonstration method for grade VII students of SMP Negeri 5 Lamboya. This study uses a qualitative approach with a descriptive method. 14 students as subjects to be researched to the extent to which the students can work on one-variable lienar equation problems. The data collection methods used are tests, interviews, and documentation. Data analysis is carried out qualitatively with the stages of data reduction, data presentation, and conclusion drawing. The results of the study showed that there was still a lack of ability of students to solve PLSV questions that answered the questions correctly and incorrectly. The results of the analysis for problems number 1, 2 and 3 were at the stage of difficulty in interpreting mathematical language (59.66%), the stage of difficulty in using data (64.33%), the stage of difficulty in mastering concepts correctly (66.66%), the stage of difficulty in using calculation operations (66.66%), and the stage of difficulty in drawing conclusions (83.33%). The cause of incompetence is that students do not read the questions carefully so that they make mistakes in writing down what is known and what is asked, so that they are less able to solve problems, in a hurry so that others are incomplete.
