Looking Back to Support Problem Solving
Dickman, Benjamin
Mathematics Teacher, v110 n1 p54-58 Aug 2016
Guessing, for Pólya, is an important way of getting an initial handle on a mathematical problem. An argument can be made to place guessing in any one of the first three steps of the four-step approach to problem solving as described in "How to Solve It" (Pólya 1945). It could be a part of understanding the problem, devising a plan, or carrying out the plan. Guessing can occur throughout the problem-solving process. Traditionally, guessing is incorporated into the work toward a solution. The authors advocate a different approach--guessing that occurs after the problem has already been solved. In this article, the author considers instead placing it in the final step--looking back.
