Heuristic Approach to Problem-solving: Examples …

To become a good problem solver in mathematics, one must develop a base of mathematics knowledge. How effective one is in organizing that knowledge also contributes to successful problem solving. Kantowski (13) found that those students with a good knowledge base were most able to use the heuristics in geometry instruction. Schoenfeld and Herrmann (38) found that novices attended to surface features of problems whereas experts categorized problems on the basis of the fundamental principles involved.
Silver (39) found that successful problem solvers were more likely to categorize math problems on the basis of their underlying similarities in mathematical structure. Wilson (50) found that general heuristics had utility only when preceded by task specific heuristics. The task specific heuristics were often specific to the problem domain, such as the tactic most students develop in working with trigonometric identities to "convert all expressions to functions of sine and cosine and do algebraic simplification."

From empirical studies, a description can now begiven of the problem-solving process that holds for a rather widerange of activities. First, problem solving generally proceeds byselective search through large sets of possibilities, using rulesof thumb (heuristics) to guide the search. Because thepossibilities in realistic problem situations are generallymultitudinous, trial-and-error search would simply not work; thesearch must be highly selective. Chess grandmasters seldomexamine more than a hundred of the vast number of possiblescenarios that confront them, and similar small numbers ofsearches are observed in other kinds of problem-solvingsearch.

Is your objection that heuristics are unreliable or invalid? On the one hand, that’s a reasonable objection because heuristics are by definition not perfectly reliable. On the other hand, it’s not like more algorithmic methods are by their nature more trustworthy simply because they’re algorithmic. After all, an algorithm can be applied in an inappropriate context, or can be based on an invalid model. The Weibull distribution is a classic example. Cem Kaner and Walter (“Pat”) Bond give a detailed refutation of its applicability to software bug-finding metrics .

Mathematical Problem Solving - Instructional Design


Methods, such as the clinical approach discussed earlier, used to gather data dealing with problem solving and individual's thinking processes may also be used in the classroom to evaluate progress in problem solving. Charles, Lester, and O'Daffer (7) describe how we may incorporate these techniques into a classroom problem solving evaluation program. For example, thinking aloud may be canonically achieved within the classroom by placing the students in cooperative groups. In this way, students may express their problem solving strategies aloud and thus we may be able to assess their thinking processes and attitudes unobtrusively. Charles and his colleagues also discussed the use of interviews and student self reports during which students are asked to reflect on their problem solving experience a technique often used in problem solving research. Other techniques which they describe involve methods of scoring students' written work. Figure 3 illustrates a final assignment used to assess teachers' learning in a problem solving course that has been modified to be used with students at the secondary level.

However, even without the ordering of differences according to importance, MEA improves over other search heuristics (again in the average case) by focusing the problem solving on the actual differences between the current state and that of the goal.

This is sometimes more colorfully described as "Finding oneself impaled upon the horns of a dilemma", referring to the sharp points of a bull's horns, equally uncomfortable (and dangerous).

generally signifies a solution designed for a specific problem or task, non-generalizable, and not intended to be able to be adapted to other purposes (compare with a priori).
