Critical Thinking

"Critical thinking is the formation of logical inferences."
Simon and Kapplan, 1989.

"Critical thinking is the development of cohesive and logical reasoning patterns." Stahl and Stahl, 1991.

"The purpose of critical thinking is, therefore, to achieve understanding, evaluate view points, and solve problems. Since all three areas involve the asking of questions, we can say that critical thinking is the questioning or inquiry we engage in when we seek to understand, evaluate, or resolve."
Maiorana, Victor P. Critical Thinking Across the Curriculum: Building the Analytical Classroom. 1992.
