What is reflection in the context of learning, and what does being able to do it accomplish? The interest in reflection began (as did so many educational topics) with Dewey, who described reflection as a two-stage process beginning with doubt, hesitation, being perplexed, and the experience of having difficulty explaining something to oneself so that it makes sense. To resolve that dissonance, the learner seeks new ideas or experiences that will resolve the doubt, settle the perplexity, or remove the difficulty. Researchers who have studied the construct have built on Dewey, but they haven’t changed his basic depiction.
