Instruction on problem solving in particular domains typically relies on explanations from experts about their strategies. However, research indicates that such self-reports often are incomplete or inaccurate (e.g., Chao & Salvendy, 1994; Cooke & Breedin, 1994). This article evaluates research on experts' cognition, the accuracy of experts'…

Paper discusses in some detail the design of a problem-solving monitor and includes an annotated student protocol and the corresponding problem-solving graph. (Author)

Focusing on the precise grounds on which a person can be said to have solved a problem, six conditions are articulated which govern the application of the concept and its relationship to trying and intention. The "solving" concept is found in synonymous phrases such as "figuring out" and "finding the solution." (Author/CM)

Reports on a study of human problem-solving behavior in which a technique called First-Order Cognitive Analysis was employed to analyze the tasks involved in certain accounting processes such as bookkeeping. A reference list, an appendix outlining the problem employed in the study, and an appendix on the task analysis are attached. (JL)

Discussion of the role of small group performance focuses on solving problems to improve performance. Types of tasks and their effects on groups are described; group resources are discussed; factors affecting group process are explained; and a flowchart for solving group performance problems is presented. (LRW)

The term "conceptual simulation" refers to a type of everyday reasoning strategy commonly called "what if" reasoning. It has been suggested in a number of contexts that this type of reasoning plays an important role in scientific discovery; however, little "direct" evidence exists to support this claim. This article proposes that conceptual…

We compared the performance of three heuristics with that of subjects on variants of a well-known combinatorial optimization task, the Traveling Salesperson Problem (TSP). The present task consisted of finding the shortest path through an array of points from one side of the array to the other. Like the standard TSP, the task is computationally…

Presents a study of preschoolers' imitation of a model's irrelevant hand gestures while performing easy and difficult tasks. (BD/BR)

Relates the problem-solving behavior of second, fourth, and sixth graders to conceptual tempo. Correlations with indices of strategic and efficient performance on a pattern-matching task confirmed that reflectives are more strategic than impulsives. A task-analysis identified the sources of inefficiency for each child and related these sources to…

A step-by-step tutorial on planning, building, and debugging a BASIC program. (JL)

Studied development of procedural knowledge in 14 adults, aged 18 to 35 years, engaged in a novel task using a toy tractor-trailer rig. Results revealed three phases of development in subjects' knowledge of steering procedures and the rig's movement patterns, and their use of feedback information. Subjects also manifested different levels of…

Given the privileged status claimed for active learning in a variety of domains (visuomotor learning, causal induction, problem solving, education, skill learning), the present study examines whether action-based learning is a necessary, or a sufficient, means of acquiring the relevant skills needed to perform a task typically described as…

Strategic communication scholars agree that planning is critical to human action. An investigation tested plan modification aspects of cognitive planning theory. Two experiments tested whether success and failure of a plan served as predictors of plan modification and whether individuals can accurately predict whether and how they will modify a…

This study was designed to determine whether modifying the task characteristics of the Stage 6 sensorimotor means-end problem (by introducing additional visual cues) aided task solution in children. Subjects were 80 children, ages 20-33 months. (CS)

This analysis of solutions to the Tower of Hanoi Problem underscores the importance of subject-by-subject analysis of "What is learned" in understanding human behavior in problem-solving situations, and provides a technique for describing subjects' task performance programs in detail. (Author/BJG)
