I saw a wonderful article by MindShift pop up in my Feedly feed (another great tool). This article, entitled "When Kids Have Structure for Thinking, Better Learning Emerges" by Katrina Schwartz, shows how teachers can get students to think more deeply about what they are thinking by making it visual.
Like me, you have probably had training on "metacognition". And you were probably taught that it means "thinking about thinking". Schwartz points out that there is more to metacognition than simply "thinking about thinking"--there is monitoring thinking and directing thinking.
