In this paper we report on a case study of a university student (third year of Mathematics course). She was engaged in proving a statement of elementary number theory. We asked her to write the thoughts that accompanied her solving process. She was collaborative and her protocol is suitable to study the interrelation between affect and cognition.…

Twelve linear algebra students were interviewed about the concept of a Solution of a System of Equations. The interviews were analyzed using APOS tools, in particular the ideas of Action, Process, Object and Schema, and Genetic Decomposition. The analysis of the interviews revealed several misconceptions of Solution. The analysis also revealed…

How do more experienced school administrators think about and attend to problems in school administration? This paper presents findings of a study that compared how principals and aspiring principals cognitively processed and solved a problem scenario. A total of 30 practicing principals and 24 aspiring principals (referred to as the "novice…

On-the-job experience is commonly regarded as the prime prerequisite for proficiency. This paper presents findings of a study that compared the ways in which a group of practicing elementary principals (n=31) and aspiring principals (n=25) thought their way through a case study. The study was conducted as part of the Cognitive Approaches to School…

The paper presents literature related to the problems and promises of interdisciplinary work. Important characteristics of effective work groups are described, and origins of difficulty in groups are discussed. Most work on groups has been based on research on groups that come together only in the laboratory. These groups are different from…

The University of Maryland offers a physics course as part of the Maryland Collaborative for Teachers' Preparation (MCTP) project. One of the course aims is to promote the learning of the concept of a function through the learning of physics. Students learn in small groups through problem solving and with the aid of microcomputer-based…

It was shown that hierarchies change with development and that relative salience of a dimension is negatively associated with both reaction time of choice and number of errors on the identity task. (Authors)

The utility of a model of cognition for developing the coding strategies of mentally retarded persons was assessed with 20 moderately and severely retarded residents (mean age 15 years) of an institution. Correlational analyses confirmed the sequential processing nature of the training tasks, and the relationship between coding and language tests.…
