A number of researchers argue that the classroom must nurture an environment providing modeling, rehearsal, and coaching, for students and teachers alike, to develop a capacity for critical thinking. Despite the difficulties, many teachers are now promoting critical thinking in the classroom. They are (1) promoting critical thinking by infusing instruction with opportunities for their students to read widely, to write, and to discuss; (2) frequently using course tasks and assignments to focus on an issue, question, or problem; and (3) promoting metacognitive attention to thinking so that students develop a growing awareness of the relationship of thinking to reading, writing, speaking, and listening.
