In this article, the author stresses that teachers need to teach their students to think critically and to reason their way. One prerequisite for teaching critical thinking is a classroom climate of high expectations, teacher warmth and encouragement, and pleasant physical surroundings. Schools should see to it that students become progressively more disciplined in their reasoning, and more self-critical and self-directed in the process and products of their thinking as they advance through the grades. She also states that the students need opportunities to analyze their own thinking according to standards of clarity, accuracy, relevance, logic, and fairness. Moreover, she notes that teachers should give necessary information and thinking tools to solve problems that focus more on affective and cognitive features of learning; and for students to become good critical thinkers, teachers must be good thinkers themselves. Furthermore, she discusses some of the possible things that a teacher should do in order to develop the students' thinking skills.
