Abstract

This research focuses on the results of the analysis of the errors that occur when students solve problems related to matrices at the high school level, assuming that there are many errors in solving these problems from different perspectives. The main purpose of this research is to find out the most common types of errors and the factors affecting them, based on the research object presented by the researcher. The study was prepared through a qualitative study, where the results of an error analysis obtained directly from the evaluation of high school students were examined. From the results of the study, it can be concluded that students' errors in solving  matrix material problems include different types of errors, which  are usually identified as errors in performing matrix operations, such as  addition or subtraction errors of matrix elements. In addition, there are  errors in understanding the basic concepts of matrices, such as errors in identifying the size of a matrix  or identifying the elements of a matrix. Contributing factors to these errors are lack of conceptual understanding, lack of practice and confusion in applying the relevant formulas.

Abstract

This study is a descriptive qualitative research for the purpose of analyzing errors and explaining the types of mistakes made by students when solving problems based on the text format provided. This research was conducted at a tertiary institution in Cianjur, with 10 research subjects in class VII B in the odd semester of the 2022/2023 academic year at SMP Negeri 5 Pasirkuda. The data collection method in this study was in the form of a written test. Based on the data presentation, the student error rate is 1) conceptual error, namely 66.9% with a "high" error percentage; 2) 10% procedural errors with a percentage of "very low" error categories; 3) 22.1% technical failure with a "low" failure percentage rate. Therefore, we can conclude that the conceptual understanding of student set material is relatively low. Therefore, the teacher should pay attention to students' conceptual understanding of the overall concept of the material and show students the important parts of the whole concept.
