Even solving simpler, more basic problems is helped by considering analogies. Psychological Science, 16(1), 1–5. .” And that was just the hint he needed: he drew lines outside the box by making them longer than the matrix and soon came up with this solution: When Rachel went to work, she took one look at the problem and knew the answer immediately: she had seen this problem before, though she could not remember where. By these definitions, the nine-dot problem is relatively well-structured—though not completely. But two volunteers tried doing it at the board, but were unsuccessful. A well-structured problem provides much of the information needed and can in principle be solved using relatively few clearly understood rules. A third helpful strategy is analogical thinking—using knowledge or experiences with similar features or structures to help solve the problem at hand (Bassok, 2003). She had also seen other drawing-related puzzles and knew that their solution always depended on making the lines longer, shorter, or differently angled than first expected. She repeated her earlier comment: “Have you assumed anything about how long the lines ought to be?”. Gestalt Theory: An International Interdisciplinary Journal, 16(2), 101–121. Algorithms are only effective when a problem is very well-structured and there is no question about whether the algorithm is an appropriate choice for the problem. The water lily problem described above is a good example: starting with the day when all the lake is covered (Day 100), ask what day would it therefore be half covered (by the terms of the problem, it would have to be the day before, or Day 99). Teachers can assist this process, as you might expect, by suggesting reasonable, helpful analogies for students to consider. Information about lily size is not relevant to the solution and only serves to distract from the truly crucial information, the fact that the lilies double their coverage each day. Many systems for problem-solving can be taught to learners (Pressley, 1995). He mused to himself: “Think outside the box, they always tell you. They do not work well, however, with ill-structured problems, where they are ambiguities and questions about how to proceed or even about precisely what the problem is about. Another helpful strategy is working backward from a final solution to the originally stated problem. Working backward in this case encourages reframing the extra information in the problem (i. e. the size of each water lily) as merely distracting, not as crucial to a solution. At this stage, learners compile relevant information and try out strategies to solve the problem. The responses of students to such problems, as well as the strategies for assisting them, show the key features of problem-solving. This approach is especially helpful when a problem is well-structured but also has elements that are distracting or misleading when approached in a forward, normal direction.
