Explored the environment for literacy in day-care centers, its relationship with traditional measures of day-care quality, and its influence on children's cognitive and language development. Observations in 30 community-based day-care classrooms revealed relatively impoverished literacy environments. Found that both day-care quality and…

Investigated the effect of using gender as a functional category in elementary school students' gender stereotyping. Results support the idea that the functional use of gender categories leads to increases in gender stereotyping, particularly among those children with less-advanced classification skills. Advanced classification skills proved to…

Developmental assumptions that are frequently regarded as constraints on elementary school science curricula are analyzed. The argument that elementary school children cannot function as experimentalists because they have not yet attained formal operational thought is not supported by the Piagetian or non-Piagetian research reviewed. (SLD)

Conservation and metaphor acquisition were studied in 35 hearing-impaired children (ages 6-19) using either cued speech or oral-aural communication. Significant positive relationships were found between conservation and metaphor in both communication modes, age and metaphor, and age and conservation. Neither conservation nor metaphor was related…

This article describes a problem-solving strategy unit to be used as a supplement to the regular mathematics curriculum at the primary level. Specific teaching steps and examples are given for three developmental stages of thinking: (1) concrete, (2) representational, and (3) abstract. (DB)

The intuitive simplicity of probability can be deceiving. Described is a dialogue that presents arguments for conflicting solutions to a seemingly simple problem determining the probability of having two boys in a two-child family knowing that one child is a boy. Solutions contain multiple arguments and representations. (MDH)

Great care must be taken when making the jump from the finite to the infinite. The concept of infinity is explored through a series of examples from infinite sequences, presenting potential contradictions that could occur from a natural extension of finding the fraction form of a repeating decimal. (MDH)

Teaching the concept of integration differs depending on which of four perspectives is used to introduce the topic. Presents a method based on the historical development of the use of integration that introduces integral as antiderivative. Discusses examples of differential equations used in the development and ways to connect this to the other…

Discussed is the idea that energy is the cause of change. This idea, going back to early cognitive development, means that the teaching of energy needs to confront how, thermodynamically, people can perform actions. The change in energy caused by differences is emphasized. (KR)

Presents a developmental approach to educating school-age children about acquired immunodeficiency syndrome/human immunodeficiency virus (AIDS/HIV). The paper describes, for three age groups, general characteristics of children's thought processes, ways in which they assimilate information about aspects of AIDS, and implications for educating…

Applies the Lesh Translation Model to develop conceptual understanding by showing relationships between five modes of representation proposed by Lesh to learn multiplication of fractions. Presents five teaching activities based on the translation model. (MDH)

Focuses on the enhancement of chemistry students' skill in problem solving utilizing problem categorization techniques. Indicates that explicit training in categorization skills can lead to higher achievement in complex problem-solving situations but that such achievement may be limited by the lack of linkages between students' conceptual…

Presents two cognitive models that illustrate the commonalities between reading for meaning and solving mathematical problems with meaning. Discusses the importance of number sense in the prior knowledge component of the solving with meaning model and the implications of the models in teaching mathematics. (MDH)

The second in a series of three articles, some themes of an undercurrent of educational objectives that move beyond the evident content goals are outlined. The themes relate the computer software materials analyzed in Part I to the cognitive experiences that students should have in learning about subject matter. (MDH)

A framework for examining racism in higher education is outlined. It distinguishes several stages of racist attitude: affective-impulsive, dualistic rational, libertarian, principled, and principled-activist. These stages of cognitive development are suggested as a model for planning intervention strategies. Some specific strategies are described.…
