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.
