Analisis Miskonsepsi Peserta Didik pada Materi Pertidaksamaan Linear Satu Variabel Melalui Two- Tier Test

Abstract

This study aims to analyze students' misconceptions on the one-variable linear inequality system materials through a two-tier test and analyze the possible causes of students' misconceptions in the one-variable linear inequalities materials. This research is qualitative research with an exploratory method. The data collection technique uses a two-tier test. The data are collected through one variable linear inequality test and unstructured interviews. The instruments used are in the form of one variable linear inequality test questions and interview guidelines. The research subject was taken in a purposive way. The results showed that (1) students' misconceptions on each indicator of one variable linear inequalities were characterized by subjects who did not understand the differences between variables, coefficients and constants, subjects who did the summation between variables and constants, subjects who did not understand the concepts related to the stories question on linear inequalities of one variable, and subjects who do not understand in making mathematical models related to one variable linear inequalities ; (2) factors causing students' misconceptions include the lack of understanding of students on the concept of linear equations and inequalities of one variable, learning the topic of One Variable Linear Equations becomes the starting point of learning the topic of One Variable Linear Inequalities, students lack of practicing questions that contain algebra which has coefficients in the form of decimal numbers, the study does not explain how the rule "change the sign of the inequality when multiplying or dividing both sides of the inequality with negative numbers" can be obtained, and contextual problems are only given as an application of the topic of One Variable Linear Inequalities.
