Considered are two commonly used techniques, the interview and word association techniques. Highlighted is a third technique called the repertory grid. This third technique can be used to interpret students' knowledge based on an explicit, psychological theory of human behavior. (Author/CW)

The science learning cycle developed by Robert Karplus and others in the 1960's has been a useful model for many science teachers and researchers. This model stresses the use of structured inquiry to organize knowledge acquisition and problem solving. Recent research in the cognitive science tradition, however, has shown that learning and problem…

Presents descriptions of play reflecting recent theories, including the psychoanalytic works of Freud, Erikson, and Peller; Piaget's developmental theory (with discussion of Sutton-Smith); and the views of Smilansky and Parten. (AS)

The purpose of this study was to develop a procedure for the evaluation of M-demand of chemistry problems. It was shown that dimensional analysis upon the Neo-Piagetian theory of Pascual-Leone could help science teachers to understand the epistemological basis of their discipline. (CW)

The results of survey of secondary school biology students used to access misconceptions about cells are presented. A distinction between conceptions, misconceptions, and nonconceptions is drawn in terms of secondary school biology concepts. The resilience of misconceptions is discussed. (CW)

Assessed was the level of thinking of 140 students who had been placed in developmental algebra as entering college freshmen. Scores on the Group Assessment of Logical Thinking, Scholastic Aptitude Tests, college placement tests; high school grade point average, and developmental algebra final grade were analyzed. Group characteristics are…

In two parallel one-year studies, solution strategies for subtraction number facts and achievement patterns of matched groups of first graders in two different instructional programs were examined. Significant differences between groups were found favoring the strategy approach. (Author/CW)

Investigated was the learning of the mathematical uses of "more,""fewer," and "less" at a very early stage in the development of ideas. (CW)

Presented are the results of an analysis of the cognitive stages of tenth-grade pupils using a six-week unit on the respiratory system. The research design, instruments, and data analysis are discussed. A variety of cognitive levels was found and may be related to learning outcomes. (CW)

A constructivist analysis of the concepts of communication and environment may go against the traditional ideas of realists. Both concepts are treated as subjective constructs of a cognizing agent. It is held that the basis of the constructivist theory of knowing as the idea that knowledge is a mapping of ways of acting and thinking and the result…

Student comments about having time in class to think and solve problems are presented. Stressed are teaching methods which allow students to familiarize themselves with the problem, think about solution processes, work through the solution process, and reflect while solving a problem. (CW)

This paper presents a theoretical framework for investigating the role of algorithms in mathematical thinking using a combined ontological-psychological outlook. The intent is to demonstrate that the processes of learning and of problem solving incorporate an elaborate interplay between operational and structural conceptualizations of the same…

Compared are the van Hiele levels of geometric thinking and the geometry curriculum recommended by the National Council of Teachers of Mathematics Curriculum and Evaluation Standards for School Mathematics. Activities which illustrate the various levels are provided by grade level with procedures. (CW)

Reported is a naturalistic study of the role of mathematical paradoxes in the preservice education of high school mathematics teachers. Findings indicate that the model of resolving paradoxes as applied in this study has relevance to such aspects of mathematics education as cognitive conflicts, motivation, misconceptions, and constructive…

This study reports on an analysis of the relation between kindergarten children's developing theory of mind and their understanding of characters' actions and consciousness in story narrative, based on Bruner's (1986) notion of the dual landscapes of action and consciousness. Wordless picture books were used to model these two aspects of…
