Defining Reflection: Another Look at John Dewey and Reflective Thinking (Rodgers, 2002)Thinking, particularly reflective thinking or inquiry, is essential to both teachers’ and students’ learning. It is the purpose of this article to restore some clarity to the concept of reflection and what it means to think, by going back to the roots of reflection in the work of John Dewey. I look at four distinct criteria that characterize Dewey's view and offer the criteria as a starting place for talking about reflection, so that it might be taught, learned, assessed, discussed, and researched, and thereby evolve in definition and practice, rather than disappear.
