Concept mapping is far from a new educational approach, but it can help students engage in improved thinking. It typically involves creating diagrams that visually represent a set of ideas. Argument mapping is a variation of concept mapping, and the approach encourages people to create diagrams of an argument’s contentions. A forthcoming research review argues that helping students create online organizers leads to stronger reasoning skills. The authors declare that mapping tools are simply “a very effective way to teach critical thinking.”
