In everyday teaching, the mathematical meaning of new knowledge is frequently devalued during ritualized formats of communication and replaced by social conventions. Specific aspects of the problem of meaning development were investigated in two second-grade teaching cases. These were used to develop decisive requirements for maintenance of an…

This article discusses basic learning processes utilized by children with profound intellectual disabilities, including classical conditioning, operant conditioning, and habituation. The article also explores how these learning processes may be used in assessing the capabilities and preferences of children with profound intellectual disabilities.…

Presented is a criticism of Lawson's (1988) article on the development of misconceptions of biological concepts. Lawson's response to this criticism follows. (CW)

The results of survey of secondary school biology students used to access misconceptions about cells are presented. A distinction between conceptions, misconceptions, and nonconceptions is drawn in terms of secondary school biology concepts. The resilience of misconceptions is discussed. (CW)

Preschool children were given a memory task that required repeating a list of animal names and a sentence imitation task. Results confirmed a relationship between word span and language imitation in younger preschool children and the notion of a memory constraint on early spontaneous language. Increasing mastery of linguistic rules appeared to…

Examined relationships among working memory, memory span, and reading skills in children and adults. Found that working memory and short-term memory skills develop through adolescence, but working memory skills show declines in adulthood. Age-related declines in memory appear to be related to the task's processing demands, which may affect the…

Discusses the question of aptitude from within an information-processing perspective, examines how aptitude is conceptualized in this framework, and discusses one possible component of L2 aptitude: working memory. (56 references) (Author/CK)

Reviews "The Epigenesis of Mind: Essays on Biology and Cognition" (S. Carey and R. Gelman, editors), a collection of essays that present a hard-scientific vision of cognitive development. Examines the arguments this work articulates and then determines the place it occupies in the analysis of the state of developmental psychology as presented in…

Illustrates some of the analytic tools and conventions associated with the construction and evaluation of dynamic models of the processes underlying learning, memory, and development. Describes a study finding that children may exhibit slower disintegration of verbatim memory traces than adults due to interference; however, adults may be more…

Reviews efforts to develop mathematical models in developmental psychology. Explores recent developments in using dynamical systems for modeling human psychological processes. Comments on the studies described in this journal issue on dynamic modeling of cognitive development. Suggests that using this framework holds great promise for clarifying…

An active learning method incorporated into one college teacher's art history survey classes encourages students to begin to express ideas about what they see through three stages of a learning cycle: exploration, invention, and application. The method can be used in almost any field and has special advantages for introductory courses. (MSE)

The development of children's causal knowledge is investigated by analyzing changes in the content and form of the explanations they generate across the age span of three to nine years. The balance of incremental versus fundamental change and the forms each takes in children coming to understand the working of gears are examined. Three phases of…

Reports the influence of piano harmonic accompaniment on singing ability of 203 kindergarten students during 1 year of instruction. Finds that no significant differences in singing ability occurred in the groups. Suggests that musical aptitude develops gradually and extensive musical exposure and instruction may be necessary to improve singing…

Presents findings from an analysis of classroom discussions aimed at constructing shared knowledge. Demonstrates how students build up new concepts by renegotiating and sharing meanings and ideas during argumentative exchanges. Suggests that collaborative discourse-reasoning can support students' gradual mastery of discursive practices…

Explores the idea that play is one of the fundamental processes by which children develop their understanding of the world by looking at play as an intrinsically motivated activity. (WRM)
