For engineering educators who incorporate real-world problems into their teaching, it is essential to understand real-world problem solving and the nature of problems for better design of the instruction. Prior research provided evidence that real-world problems involve many stakeholders, are complex, and have multiple solutions and solution paths. The purpose of this paper is to provide additional insights particularly into the structure/class of workplace problems and associated models of expertise. This paper describes the findings of a study that employed a two-step process: (1)?a single-case study of a steel engineer generating a model of compound problem solving and (2)?a multi-case comparison of 90 problem-solving narratives of other engineers to the single case. The study is located in a U.S. context. Results indicate that real-world problems are intertwined problems (compound problems) and that transitions from one problem type to another within a compound problem are a unique class of problems themselves. These transition problems have properties that are not represented in other problem types and provide insights into expertise and expertise development in problem solving. 相似文献

Four experiments examined whether verbalization can interfere with insight problem solving. In Exp 1, Ss were interrupted during problem solving and asked either to verbalize their strategies (retrospective verbalization) or engage in an unrelated activity (control). Ss in the retrospective verbalization condition were significantly less successful than control Ss at solving the problems. Exp 2 replicated the finding of Exp 1 and demonstrated that the control Ss' advantage was not due to any beneficial effect of the interruption. In Exp 3, concurrent, nondirective verbalization impaired the solving of insight problems but had no effect on noninsight problems. In Exp 4, the effect of concurrent verbalization on insight was maintained even when Ss were encouraged to consider alternative approaches. Together, these findings are consistent with the hypothesis that verbalization can result in the disruption of nonreportable processes that are critical to achieving insight solutions.

Two studies examine how the time at which problem solving is suspended relative to an impasse affects the impact of incidental hints. An impasse is a point in problem solving at which a problem solver is not making progress and does not know how to proceed. In both studies, work on remote associates problems was suspended before an impasse was reached, at the time an impasse was reached, or after a period of continued work during an impasse. After problem solving was suspended on a set of problems, participants completed a lexical decision task before resuming work on the set of unsolved problems. For half of the problems suspended during each impasse state, solution words were presented as incidental hints in the lexical decision task. The proportion of initially unsolved problems that were solved after the intervening lexical decision task was greater when problem solving was suspended at the point an impasse was reached than when problem solving was suspended before an impasse or after a period of continued work during an impasse. These results suggest that suspending problem solving at the point of impasse may increase susceptibility to incidentally presented hints. The point of impasse may be an opportune time for hints because the problem has been explored but there has not been a large increase in fixation on failed solution attempts.
