This topic brief is one in a series on personalized learning prepared for Conversations with Innovators, 2018. Metacognition is one of the four essential personal competencies emphasized by the Center on Innovations in Learning. Simply stated, metacognition is the process of thinking about thinking. It involves self-reflection: on one's current state, history, future goals, possible actions, and potential results and hence is critical in all aspects of school and in life. Learning pictures support visual thinking. They help students clarify and organize their thoughts about how they are doing and think analytically, for example, whether it is time to celebrate, keep on going, or try something different. Thinking and talking about their learning pictures provides critical practice in self-reflection, self-evaluation, and other social emotional competences. It supports thinking about presenting information in visual or graphical ways--how well the information is communicated to oneself and to others. This report presents how metacognition can be increased through learning pictures.
