Study of student error thinking in solving Cognitive Reflection Test (CRT) required from Dual Process Theory (DPT)

Abstract

This study aims to describe the mistakes of students thinking in solving the problem of Cognitive Reflection Test (CRT) based on dual process theory especially on system 1. The research approach is qualitative by taking the subject as much as 2 students in Senior High School (SMA) 4 Ternate City. The results showed that there are 2 categories of student error in solving mathematical problems using system 1. Where students who solve problems using system 1 but wrong and students who solve problems using system 1 and correct but have no logical reason. The misconception of the students identified is on understanding the concept and modeling of mathematics.
