Findings from two studies of fourth grade children learning the concept of mathematical equivalence are presented. The questions studied were: (1) Can knowledge conveyed in gesture but not in speech be tapped by a recognition technique; and (2) Does having implicit knowledge that is expressed in gesture but not in speech have implications for…

The goal of the Toledo, Ohio, Support Teacher Programs has been to improve the learning of math and science concepts at the junior high school level. This goal involves some basic changes in the way teachers interact with each other and with their students. The greatest changes have been in the movement away from the…

This paper addresses two distinctive issues concerning animistic and anthropomorphic thought in the context of constructivist science education. The first concerns the extent of such ways of thinking, both within science itself and within school science. The second concerns the implications of this for theories of instruction in science education.…

An experiment examined whether children of different developmental stages expressed different levels of fear while viewing episodes of the television program, "The Incredible Hulk." Preoperational (3 to 5 years old) and concrete operational (9 to 11 years old) children were shown short videotaped segments taken from the program. Using…

This report describes a study on the development of children's conceptualizations of written language, that is, their graphic sense. The study investigated three issues: (1) whether acquisition of literacy is a developmental process common to all normal children, (2) whether the levels of graphic sense tend to be associated with particular…

The paper provides an analysis and synthesis of studies with hearing impaired and other populations concerning the cognitive development of the principle of liquid horizontality--the idea that still water remains invariantly level regardless of the angle of the container. Three major questions focused the investigation: (1) What are the effects of…

Examined is the notion of "representation" as it is used in mathematics education. The first section explains what appears to the current "received view" of representation within mathematics education. The second section describes the constructivist view of representation, especially as this view is related to Piaget's theory. The third section…

An inquiry attempted to build an agenda for research that would result in a cognitive theory of instruction capable of informing educational practice and extending the limits of knowledge about how people learn and develop. What would such a theory look like, how close are we to having one, and what directions must be followed to further its…

This report presents a general framework for studying the acquisition and cognitive representation of biomedical concepts and analyzing the nature and development of misconceptions. The central approach of the report is a selective and highly concentrated analysis of the true nature of clusters of complex concepts and the manner in which they are…

Over the past several years, one study after another has uncovered a positive relationship between interpersonal interaction and individual achievement. According to a handful of these studies, interaction is more effective than are individually-based strategies for promoting reasoning. We give our attention here to the link that possibly exists…

The current study was devised to determine the short-term (1 month) and long-term (4 months) effects of having students generate their own examples of selected concepts. More specifically, focus was on determining how self-generated examples might enhance the learning and retrieval of concepts. Subjects were 55 (54 female and 1 male) undergraduate…

One aspect of Jean Piaget's theory of cognitive development was tested in this research project. It was hypothesized that an adult individual in the concrete stage of development is able to use seriation and classification in dealing with concrete objects, but is unable to think in terms of possibilities. An individual operating on the formal…

Working under the hypothesis that a child's concept of a story and his or her concept of the task of narration used to tap comprehension emerge first in social interaction, a methodology was created for studying the process of development from dependent functioning in social interaction to independent functioning based on L. Vygotsky's theoretical…

This study sought to determine the basis for young children's understanding of fundamental addition and subtraction processes, and to expose any limitations on such arithmetic reasoning. Thirty-six two-year-olds and 36 three-year-olds participated in six experiments which examined children's relational quantity judgments about pairs of arrays in…

Interpretation of experimental tasks is influenced by knowledge of the language used, by assessment of what the experimenter intends, and by how subjects themselves would normally represent the physical situation. Whether these processes in which children engage in cognitive studies differ from those employed by adults in similar tasks was…
