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…

This article investigates several methods of identifying individual guessers from their response data. Both the posterior probability method and the likelihood ratio method are based on the two-state mixture modeling approach to response times. The accuracy method is based on response accuracy data. Results from the simulation study showed that…

Computer-assisted instruction systems have been broadly applied to help students solve math word problem. The majority of such systems, which are based on an instructor-initiating instruction strategy, provide pre-designed problems for the learners. When learners are asked to solve a word problem, the system will instruct the learners what to do.…

A theoretical model and methodology is presented that allows the path or trajectory of an individual's emotional experience during problem solving to be depicted and empirically studied. The trajectory of one's emotional experience reveals how well the individual copes with the frustration of problem solving by indicating how quickly recovery…

While little is known about the processes of creative cognition or about the structure of human memory, scholars do understand the immense task of unraveling the cortical structure and function of the human brain. Existing literature on creativity appears to obscure the processes of creativity far more than it clarifies the creative act. However,…

This paper address three questions: (1) What is the nature of design? (2) How do skilled designers function? and (3) Can a theory of design be constructed which will allow novice and expert instructional designers to perform their tasks more efficiently and effectively? It begins by presenting two general theories of design: Simon's conception of…

Reports on two types of unsolvability in mathematics. One is an instance of impossibility and the second is a judgment of undecidability. Presents a number of examples of undecidable propositions. (GS)

Basic medical science has primary paradigms from which are derived secondary paradigms that allow the practice of medicine. Medical education consists in students acquiring this paradigm and in practitioners changing their paradigm in the light of medical research. (Editor/PG)

The cognitive processes involved in a child's interaction with the linguistic environment are discussed. Specifically, the general cognitive processes involved in outputting long spans of connected utterances are examined. Narrative data are classified into three developmental levels: the procedural phase, where the linguistic output is generated…

This document consists of three papers. The first, "A Parallel Model of (Sequential) Problem Solving," describes a parallel model designed to solve a class of relatively simple problems from elementary physics and discusses implications for models of problem-solving in general. It is shown that one of the most salient features of problem…

Decisionmaking involves the conception of the situation, a perception of the attitudes of others toward the problem, an understanding of the various alternatives available and their predictable consequences, and an ability to predict the acceptance of any given decision. The author contends that to regard implementation of the decision as part of…

Assessed the relative difficulty in the utilization of oddity and matching response strategies in 144 children, ages 5-13 years. A model of matching and oddity problem-solving is presented based on the data collected. (Author/ED)

The term "problem-solving" covers three steps of the comprehensive planning process: problem analysis, generation of alternative solutions, and selection of policies or programs from those solutions. After goals have been developed and needs assessed, the problem-solving process begins with identification and definition of the specific nature of…
