Critical Thinking in Mathematics: A Must-Thinking Process to be Developed in Mathematics Classroom

Abstract

This paper aims to present critical thinking in mathematics which is a part of the authors’ research. Critical thinking in mathematics is related to thinking, reasoning, and critical thinking. The authors define critical thinking in mathematics in four aspects which are the following: 1) building mathematical ideas through explaining, questioning, and organizing, 2) using mathematical understanding to generate, and create new ideas, 3) providing reasons or judgments, and 4) performing ways to solve mathematical problems. The authors also present the related components of it which are questioning, reasoning, and problem solving.
