The causes of students’ misconception were identified using a students’ response questionnaire with three indicators of misconceptions causes, namely context, students’, and teachers. The data of students’ questionnaire were analyzed using a Likert-4 scale. The result showed 42.1% of students’ experienced misconceptions, 37.8% of students’ know the concepts, and 22.4% of students’ did not know the concepts.
