Previous research (e.g. "Cognition" 64 (1997) 73) suggests that the privileged level for inductive inference in a folk biological conceptual hierarchy does not correspond to the ''basic'' level (i.e. the level at which concepts are both informative and distinct). To further explore inductive inference within conceptual hierarchies, we examine…

Cognitive, home, and family factors that theoretically could influence whether or not preschoolers' interests were focused on domains characterized by the acquisition of knowledge concerning object concepts (e.g., dinosaurs, horses) were assessed in a short-term longitudinal investigation of 211 4-year-olds. Boys were six times as likely as girls…

This article takes the view that in a globalizing context the concept of "sustainable development" should not be assumed uncritically. Further, tensions arise when education is constructed as an instrument for the implementation of this concept, as manifest in the term "education for sustainable development". With critical concern about…

Underpinning science education reform movements in the last 20 years--at all levels and within all disciplines--is an explicit shift in the goals of science teaching from students simply creating a knowledge base of scientific facts to students developing deeper understandings of major concepts within a scientific discipline. For example, what use…

For over one hundred and fifty years practitioners, critics, and historians have continuously challenged and added dimensions to the meaning and uses of photography. Yet there has been little challenge to its highly disturbing linguistic conventions. By uncritically accepting and using these conventions, those involved in the culture of…

Eight experiments were conducted to examine 3- and 3.5-month-old infants' responses to occlusion events. The results revealed two developments, one in infants' knowledge of when objects should and should not be occluded and the other in infants' ability to posit additional objects to make sense of events that would otherwise violate their…

The author discerns two trends ruling with many of the teachers, intellectuals, and citizens of the United States. One is the color-blind-myth that Williams (1997) cites in her essay, "The Emperor's New Clothes": "I don't think about color, therefore your problems don't exist," is the phrase that she attributes to this "school of idealism". The…

When students are given opportunities to use their knowledge to explain interesting and appropriate evolutionary phenomena, their potential for understanding evolutionary concepts increases. In this article, the authors describe a nine-week high school evolutionary biology course designed to engage students in using Darwin's natural selection…

The present study investigates the development of children's ability to make inferences about a peer's mental state. In this study 48 eight-year-old children, 49 ten-year-old children and 44 adults observed and analyzed short video sequences, extracts from a socio-cognitive interaction between two children working on a mathematical task. The…

The emphasis of most simulations in chemical engineering education seems to be on teaching students how to use simulations to solve typical engineering problems. The authors have found little evidence of simulations being explicitly used to develop conceptual understanding, and therefore sought to investigate their potential use in this regard. In…

This article explores the motives and evolving identities of one group of graduate students enrolled in a teacher education program at an Ivy League university, who made the choice to teach in urban classrooms. The authors examine the perspectives these candidates give to the process of learning to teach and how their identities are tempered,…

Studies such as the Effective Teachers of Numeracy Study (Askew, Brown, Rhodes, Johnson, & Wiliam (1997) have contributed much to our understanding of what constitutes effective teaching of numeracy. This paper aims to build on these findings and to contribute a model that could be used to understand teachers' numeracy practices and the…

The research deals a problem of primary pupils' preconceptions about a child prenatal development. Even the pupils cannot experience the phenomenon and can get only mediate information; their idea about the prenatal development is quite well constructed. The quality of the preconceptions depends mainly upon variety of informational sources kept at…

Several researchers have noted how children's whole number schemes can interfere with their efforts to learn fractions. An Australian study found that children who were successful with the solution of rational number tasks exhibited greater whole number knowledge and more flexible solution strategies. Behr and Post (1988) indicated that children…

This paper presents a conceptual framework for fostering teacher professionalism in Government primary schools in Karachi, Pakistan. The framework identifies various stages for enhancing and sustaining teacher professionalism. These stages have been derived from in-depth multiple case studies of four Government primary schools in Karachi where…
