I have found it significant to visualize teaching and learning not as a duality but as a trinity, a grouping of three processes linked as one. This linking seems to best validate the adage “It hasn’t been taught until it’s been learned.” First, learning to learn leads to self-awareness of learning, described as the essential stage of knowing that guides both teacher and learner in mastering relevant content. Second, teachers learn about teaching so that content can be developed into learnable formats.
