This study examining children's understanding of biological inheritance addressed four central questions: (1) are young children able to distinguish between the relative influences of nature and nurture in their understanding of how physical characteristics versus behaviors and preferences develop in animals? (2) does children's understanding of…

This paper describes the use of radical constructivism as a basis for curriculum reform in university mathematics courses and reports on research conducted on two of the courses developed, one in geometry and one in problem solving. The theoretical underpinnings of the project are described along with the implications for course design and…

Cognitive development is driven by experience, but is mediated by domain general processes, which include learning, induction, and analogy. The concepts children understand, and the strategies they develop based on that understanding, depend on the complexity of the representation they can construct. Conceptual complexity can be defined in terms…

This study examined children's explanatory style for health- and safety-related events. Fifty children (ages 8 to 11) were interviewed using 12 health-related questions based on Seligman's Content Analysis of Verbatim Explanations (CAVE) method. Children and their mothers also completed a health status form, which included questions on the…

Three experiments examined the relation between language acquisition and other symbolic abilities in 18- and 26-month old infants. Infants' ability to learn either words or symbolic gestures as names for object categories were compared across age groups. Findings indicated that infants at both ages learned novel words as symbols for object…

A major theoretical issue in the study of language processing and language acquisition is whether language development is independent of other aspects of cognitive development, encapsulated in a "language module." This issue is discussed as it relates to lexical processing. The paper begins with a historical contextualization of the modular view…

A path from adolescence into adulthood is mapped from the accounts of college students. The evolution in students' interpretation of their lives is seen and understood through changes in the "forms" in which they conceptualize the issues they face. These forms characterize the underlying structures that students explicitly or implicitly impute to…

This essay explores the characteristic failure of traditional formal educational methods to teach the learner much which will remain for long in that person's memory. It discusses a physiological model of learning/remembering and compares it to some other models and metaphors of cognition. It distinguishes between learning and remembering, and…

Bright Start is a preschool program designed to assist caregivers and educators of children ages 2 through 5 years become optimal facilitators of young children's learning through enhancing the quality of their interaction with children and through providing mediated learning experiences. This paper examines the cognitive approach to preschool…

Noting research indicating that the flow of interaction with infants influences their brain development, this viewer's guide and videotape examine characteristics of early brain development and how parents can positively affect the infant's development in a number of areas. The first part of the viewer's guide provides an overview of the…

This document examines the use of measurement tools to evaluate children's psychological development. The first part of the document discusses the identification and quantification of developmental landmarks and the reasons for evaluation. The second part reviews several evaluation instruments. The Ruth Griffiths mental development scales are used…

This paper discusses factors that relate to the development of children's theory of mind. Cognitive and biosocial views of the development of theory of mind are distinquished. The paper maintains that all cultures recognize the intentional personhood of children in the first two years, though they vary in their methods of dealing with this…

Mathematical concepts presented within disciplines outside mathematics are either assumed to be already familiar to the students, or else, they are regarded as being peripheral to the appreciation of the content of the nonmathematical lesson. Because it is routinely included without regard for possible students' interpretations, the mathematical…

A total of 48 Canadian, middle-class 3-year-olds participated in a study of their abilities to predict the actions of a story character with a false belief and a story character engaged in pretence. In the experimental situation, a red puppet with pen-markers for legs left an "inky trail" to the location of a hidden treasure in one of…

Piaget noted that young children cannot think in a logical fashion, objectively, or about hypothetical situations. These limitations of preoperational thinking render the young child dependent upon or bound by perceptions. Overreliance upon perceptions results in children's inability to distinguish fantasy from reality. Young children's…
