Abstract

Abstract This research aims to describe the forms of student misconceptions and the factors that cause misconceptions experienced by students in solving linear inequality problems with one variable containing absolute values in class X SMA Muhammadiyah 1 Pontianak. The subjects of this research were students of class X IPA 3 SMA Muhammadiyah 1 Pontianak, totaling 25 students. The research uses descriptive method as the research method. Case study is a form of research used. The results of the research revealed that the research subjects experienced five forms of misconception, namely notation misconceptions experienced by 1 student or by 4%, generalizing misconceptions experienced by 3 students or by 12%, misconceptions of the application of rules experienced by 6 students or by 24%, calculation misconceptions experienced by 2 students or by 8%, and specialization misconceptions experienced by 3 students or 12%. The misconceptions experienced by these students are caused by wrong intuition and incomplete reasoning, where students' intuitive thoughts that arise spontaneously when solving problems are still wrong and students' reasoning or logic is still wrong in drawing conclusions and being too broad in generalizing. Keywords: Misconceptions, Two-Tier Diagnostic Test, One Variable Linear Inequality Problem with Absolute Values

Abstract

Based on the results of the study, in general there are still many students who experience errors in solving problems on the material of a two-variable system of linear equations. The errors experienced by students based on student error indicators are as follows. wrong in choosing a formula or method to solve the problem, wrongly determining the unit of the object in the problem, wrongly writing what to askand know about the difficulty, wrong in using the rules that exist in the elimination and substitution method, wrong perception in interpreting the meaning of the problem. questions, as well as misperceptions between methods of elimination and substitution. While the overall factors causing the error include the following. Factors that come from within students, namely the lack of mastery of the material and lack of interest in mathematics. Factors that come from outside the students are the way the teacher gives lessons.
