I teach the study of creativity and problem solving. We use the Crative Problem Solving Thinking Skills Model which requires divergent and convergent thinking skills in each process step. Mind-Tools provides additional explanation of many of the tools we use to stimulate divergent and convergent thinking. Students find it helpful to explore these tools in different contexts.
This site is helpful also to business clients who often aren't looking for an academic explanation, just a way of working toward a solution. The site is easy to use and searchable.
