The purpose of this study is to apply the attribute hierarchy method (AHM) to a sample of SAT algebra items administered in March 2005. The AHM is a psychometric method for classifying examinees' test item responses into a set of structured attribute patterns associated with different components from a cognitive model of task performance. An…

The relationship between working memory, intelligence and problem-solving is explored. Wittmann and Suss [Wittmann, W.W., & Suss, H.M. (1999). Investigating the paths between working memory, intelligence, knowledge, and complex problem-solving performances via Brunswik symmetry. In P.L. Ackerman, R.D. Roberts (Ed.), "Learning and individual…

An emerging body of research suggests that a set of broad "21st century skills"--such as adaptability, complex communication skills, and the ability to solve non-routine problems--are valuable across a wide range of jobs in the national economy. However, the role of K-12 education in helping students learn these skills is a subject of current…

This module is designed to apply mathematical models to nuclear deterrent problems, and to aid users in developing enlightened skepticism about the use of linear models in stability analyses and long-term predictions. An attempt is made at avoiding overwhelming complexities through concentration on land-based missile forces. It is noted that after…

This study investigated a theoretical structure which attempts to explain the problem-solving strategies used by first-grade students who are successful in solving simple arithmetic story problems. The structure used describes the problem-solving procedure as consisting of a three-stage model building process: (1) comprehending the story, (2)…

Applies the Lesh Translation Model to develop conceptual understanding by showing relationships between five modes of representation proposed by Lesh to learn multiplication of fractions. Presents five teaching activities based on the translation model. (MDH)

Most theories of instruction rely on a model of the learner's internal processing system. In this article, three general models of the internal processing system involved in learning to solve problems will be outlined, and will be related to both external instructional procedures and learning outcome variables. (Author/DEP)

The article reports results of a survey of 150 curriculum planners about their knowledge, attitudes, and behavior regarding deliberate development of creative thinking and problem-solving skills. A six-step creative problem-solving model is proposed. (CL)

A model suggesting that dissatisfaction unfolds into a hierarchical arrangement is presented. The hierarchy begins with unease/disgust and proceeds upward with conscious awareness/articulation, active solution/action orientation, frustration/concern, and concludes with despair/fear/depression. (JC)

Features of this model for technology education are human needs and wants, problems/opportunities, resources, technological processes, technological knowledge, evaluation, and solutions/impacts. (SK)

The paper discusses the iterative nature of problem solving; operant analysis of the response repertoire available in a problem situation; the likelihood of reaching a solution versus escaping from the situation; and the relationship between exiting with solution and exiting without solution, modeled on catastrophe theory. (JDD)

The scientist-practitioner professional judgment framework for psychologists is reviewed, and three judgment components are identified--the range of alternatives in professional behaviors; identification of personal practice style; and potential error sources. Strategies to analyze professional judgments, and conceptual links between analysis of…

A series of experiments involving more than 40 mechanical engineers and engineering students with different levels of expertise examined strategies, competence, and style of the designers in problem-solving behavior. A model is proposed that explains differences in designing as an interaction of domain-specific and heuristic competence. (SLD)

This paper first reviews existing models of creative problem solving in art and then proposes the Model for Idea Inception and Image Development in Art. This model consists of five stages: (1) associative exploration; (2) problem parameter exploration; (3) multiple focus exploration; (4) primary focus exploration; and (5) refinement. (Author/DB)
