what is the main idea in this story ? (1) Problem solving involves applying existing knowledge and previous experience. (2) It may also involve seeking new knowledge. (3) It requires some degree of intuition. (4) Analysis—breaking the problem down into its component parts—is also crucial. (5) So is synthesis: bringing together various aspects of the problem so as to comprehend them as a unitary whole. (6) Spatial abilities come into play as well. (7) Logic and a sense of causality are essential: the problem-solver must be able to draw reasonable inferences, avoid unreasonable inferences, and recognize what effects follow from what causes. (8) A sense of procedure—stepwise progression—is needed, too. (9) Overall, problem solving is the most complex kind of learning.
