Discusses the nature of technological literacy, considering its relationship to science education, mathematics education, and computer science education. Indicates that technological literacy is a skill and an attitude which is basic to contemporary society. Problems related to cognitive development are noted. (JN)

Some of the literature related to preschool mathematical experiences and their effect on the development of how the child perceives the relationships of mathematics is reviewed. (MP)

The goal of this article is to identify and disseminate several important messages from recent research on formal thought. Reasoning by adolescents, measurement of Piagetian formal reasoning, the importance of additional factors, stages, and working memory are discussed. (MNS)

This discussion is primarily designed to increase teachers' awareness of Piaget's theory of cognitive development and implications for mathematics in the middle school. It is hoped such awareness will compel instructors to adopt strategies that help pupils gain more from mathematical experiences, by providing impetus for innovation and…

Reasons for the development of middle schools and characteristics of middle school students are discussed. Students' physical, cognitive, social, and emotional development are considered, with references to research evidence. (MNS)

Some possible uses of math lab materials and activities that are natural and appropriate to the development of process skills are explored through a discussion of a geoboard activity. (MP)

Presents a developmental taxonomy which promotes sequencing activities to enhance the potential of matching these activities with learner needs and readiness, suggesting that the order commonly found in the classroom needs to be inverted. The proposed taxonomy (story, skill, and algorithm) involves problem-solving emphasis in the classroom. (JN)

Provides the instructions to build a homemade calculator that can be used as a reinforcement device to assist primary students in memorizing their addition facts. (MDH)

This study explored questions about the effect of lesson structure and cognitive development on science achievement of 42 students in grades four and five in British Columbia. Increased lesson structure did not significantly increase achievement, and interaction effects were generally nonsignificant. Conservation ability significantly affected…

This second part of a review on teaching science to middle school students notes Piagetian ideas related to the learning of these students and focuses on the curriculum and needs of students. (MNS)

Early childhood education today is seen as multifaceted, with its philosophical roots involving three major views: (1) Behaviorist-Environmentalist; (2) Maturationist; and (3) Comprehensive-Interactionist. How these views translate into educational practice is detailed. (MP)

Discusses the use of middle-school students' natural understanding of large numbers to introduce the concept of infinity. Presents activities that investigate infinite sets by demonstrating a one-to-one correspondence between the counting numbers and the given set. Examples include prime numbers, Fibonacci numbers, fractions, even and odd numbers,…

Student problem-solving behaviors are analyzed using a four-dimensional framework with related detrimental factors identified for each dimension. General approaches and specific techniques developed to address negative factors are reviewed. Examined are means of developing the components of problem-solving teaching. (KR)

Pattern recognition is viewed as a fundamental cognitive skill that lays the groundwork for the ability to form abstractions and generalizations. Incorporating patterning into the curriculum of young children is encouraged. (MP)

Investigated developmental and/or sex components of energy attitudes using Kuhn's Energy Opinionnaire. Results indicate that changes in student attitudes through grade levels are consistent with cognitive and affective development literature and that sex differences are more pronounced in older students (with females having a more external world…
