Reflective thinking was introduced by John Dewey in 1910 as a process to improve learning. It involves actively analyzing past experiences and knowledge to make judgments. Reflective thinking helps learners develop higher-order thinking skills by prompting them to relate new knowledge to prior understanding, think abstractly, apply strategies flexibly, and understand their own thinking. For reflective thinking to be effective, teachers must allocate time for reflection, facilitate analyzing experiences, and encourage sharing insights with others. Critical thinking is a related concept involving purposeful, reasoned thinking to solve problems and make decisions. It includes reflective thinking as the process of analyzing and judging what has occurred.
