Plausibility has been implicated as playing a critical role in many cognitive phenomena from comprehension to problem solving. Yet, across cognitive science, plausibility is usually treated as an operationalized variable or metric rather than being explained or studied in itself. This article describes a new cognitive model of plausibility, the…

In two studies, children participated in route-planning tasks in which they were asked to find the shortest path to retrieve certain items. In Study 1, children participated in two versions of the task (standard versus feedback) differing in the amount of contextual support. Forty-eight children, ages 6, 8, and 10 years, had to help their…

Four papers from a project concerning information-processing characterizations of the knowledge and processes involved in design are presented. The project collected and analyzed verbal protocols from instructional designers, architects, and mechanical engineers. A framework was developed for characterizing the problem spaces of design that…

This paper on the nature of expertise discusses implications of findings of an earlier study into the problem-solving, problem-finding and thought processes of 3 groups: 20 professional artists (experts), 20 semiprofessional artists (non-experts), and 20 non-artists (novices), each group consisting of 10 male and 10 female adults. Subjects were…

In earlier times, practically everything was taught by apprenticeships. Schools are a recent invention that use many fewer teaching resources, but the computer enables us to go back to the resource-intensive mode of education, in a form called cognitive apprenticeship. This involves the use of modeling, coaching, reflecting on performance, and…

A study examined the extent to which common knowledge structures and the presence of common performance components are important factors in reasoning. The eye fixations of 37 college students were recorded as they solved four types of complex inductive reasoning tasks: (1) verbal analogies, (2) figural analogies, (3) verbal series completions, and…

Author presented a theory of thinking designed to multiply our power as thinkers, problem-solvers and learners. (Author/RK)

The hypothesis that adolescent psychiatric patients would be deficient with respect to normal controls in their interpersonal problem-solving skills was tested by comparing the patient and control groups on seven tasks ref lecting different aspects of problem solving. (Author)

This paper represents one portion of an ongoing effort to elaborate on pedagogical principles based on structural-developmental (largely Piagetian) theory and research. Here, a concept of "problem structure" is developed as a means for identifying physical factors that contribute to children's ability to apply experimental reasoning.…

Some aspects of the relationships among the symbolic representations (Rs) of problems given to students to solve, the Rs that students use to solve problems, and the accuracy of the solutions were studied. Focus was on determining: the mental Rs that students used while solving problems, the kinds of translation that takes place, the accuracy of…

This chapter from a longer work concerns the ability of children to solve arithmetic word problems. The studies reviewed suggest that, with age, children's improved ability to solve word problems primarily involves an increase in the complexity of conceptual knowledge required to understand the situations described in those problems. Considered in…

This monograph provides teachers with a wide range of articles on the teaching of problem solving in the mathematics classroom. The first section, on Understanding the Problem, includes articles which provide a sense of the "problem" of teaching problem solving. The second section, on Devising a Plan, provides suggested plans for…

The teaching of critical thinking requires an understanding of the term, defined in this document as the processes of judgement or evaluation. Informal logic teaches students to understand and analyze arguments which are fallacious, to determine what is valid and invalid, and to evaluate non-deductive arguments. John McPeck and Richard Paul…

Research has not clearly determined whether memory development in childhood and adulthood can be accounted for by the age variation of cognitive processes other than memory. To examine this issue, a study was conducted based on a model of structures and processes in complex information processing. Subjects (N=162) were presented with two lists of…

Described in the context of a computer simulation are highlights of a program of research focusing on the storage of mathematics problem solving information in young children's memory and the development of such knowledge structures in older children. Specifically discussed are the problem size effect, the network nature of the memory…
