Abstract

Quadratic equations are an important topic in mathematics at the secondary school level because this topic is widely used in solving problems in subsequent materials such as functions, logarithms, trigonometry, and several other materials. However, many students still make mistakes in solving quadratic equation problems. This study aims to get an overview of student errors in solving quadratic equation problems. The method used in this research is a systematic literature review. After going through the inclusion and quality test stages, the literature reviewed was 12 articles. The results of this study show that there are several student errors in quadratic equation material, namely concept errors, procedural errors, and operation errors and the factors that cause them are students not understanding the problem well, not understanding the sequence of steps used to solve the problem, and not being careful in calculating the final result, forgetting, answering originally and rushing in calculating.

Abstract

This research aims to describe students' errors in solving story problems related to quadratic functions and identify the underlying factors causing these errors. The research conducted is qualitative. The study took place in one of the junior high schools in South Kalimantan, involving 5 subjects from Grade IX. The research instrument used was three descriptive story problems—data collection techniques involved analyzing the answers to the descriptive test and conducting interviews. Based on the analysis, the types of errors made by the subject are as follows: 1) Misread-direction errors (30%): Students failed to read the instructions properly due to rushing or being unfamiliar with reading question instructions. 2) Careless errors (40%): Students made calculation mistakes due to lack of attention to detail. 3) Concept errors (20%): Students lacked understanding of quadratic function concepts due to insufficient study. 4) Application errors (33.33%): Students could not apply concepts and formulas effectively in solving problems due to a lack of comprehension of the subject matter. 5) Test-taking errors (66.67%): Students failed to restate information from the problem because of being in a hurry and unfamiliar with solving story problems.
