Problem solving: “what you do when you don’t know what to do.” What a simple, straightforward definition for something often defined in much more complex ways. But problem solving doesn’t always mean the same thing. It might be the solution to a specific problem, like those that appear on math quizzes, or it might be a collection of possibilities that respond to a complex open-ended problem. But however it’s defined, problem solving is one of those skills all teachers aspire to have their students develop.
