This research review identifies similarities in skill acquisition across the domains of reading and math disabilities, specifically addressing the sequence of skill development and the theoretical question of whether the disabilities reflect delays or deficits in cognitive development. The paper discusses the nature of differences between learners…

Examines the doctrine of "constructivism" as presented by Ernst von Glasersfeld. Part 1 attempts to elicit a clearer statement of the concepts, positions and arguments for constructivism. Part 2 discusses the problem of intersubjectivity in constructivism. Part 3 ventures an explanation of at least some on the weaknesses in the doctrine.…

Discusses Piaget's and Garcia's work that examines the common features underlying individual and historical development. Presents criticism to Piaget's position and examines the possibility of overcoming the main problems of Piaget's approach within a Piagetian framework. Looks at the consequences of the relationship between individual and…

Uses Laudan's model of scientific change to obtain corresponding features on conceptual change in science learning. Discusses some practical consequences for science education. (MDH)

Discusses Lawrence A. Hirschfeld's (1995) experiments, which Hirschfeld claims demonstrate that preschoolers use a biologically grounded theory in reasoning about race. Argues that the methods used cannot address the issue and therefore, the results do not support Hirschfeld's claims. Maintains that the experiments fail to demonstrate that 4- and…

Responds to John J. Kim's critique of his studies of preschoolers' understanding of race. Maintains that his and others' investigations demonstrate that preschoolers differentiate the pattern of causal reasoning governing transmission and maintenance of racial characteristics from that governing transmission and maintenance of perceptually similar…

Traced emergence of elaborated framework of belief-desire reasoning. Preschoolers and adults were asked to explain why a story protagonist searched for a desired object in an incorrect location. Results suggest that, during late preschool years, conception of cognitive activities as contributing to knowledge and belief becomes integrated into…

Comments that fuzzy-trace theory is broadly comprehensive and contains compelling experimental manipulations; debates assumptions of the theory. Describes aspects of the historical and theoretical context of the theory and its usefulness in organizing false memory phenomena. Suggests some limitations concerning the representation of child…

Describes the origins of fuzzy-trace theory, including Piagetian, interference, information-processing, and judgment and decision-making influences. Discusses similarities and differences between fuzzy-trace theory and other approaches to memory falsification. Considers the theory's predictions regarding age differences in memory falsification and…

This study examined above-grade-level abstract reasoning abilities of 150 students (grades 2-6). Understanding of abstract concepts varied by age for only four of eight subscales or concepts: probability, proportion, momentum, and frames of reference. Performance varied widely within age level for the understanding of volume, correlation,…

This study compares scores on the Alternate Uses Test of 19 Australian children (ages 4 to 12) with severe visual impairments, and 19 controls. Comparison of mean scores revealed no significant differences between groups, however, the range of scores reflected in the standard deviations were higher for those with visual impairments. (CR)

Examines the concept of number sense in mathematics learning, compares this concept to that of phonological awareness in reading, and urges application of existing research to improving mathematics instruction for students with mathematical disabilities. Reviews research on building automaticity with basic facts, adjusting instruction to address…

Reviews selected pioneering findings in the child-developmental and adulthood-aging literature and evaluates them within the framework of Nelson (Thomas O.) and Narens' (Louis) (1990) theory of metamemory. Makes suggestions for conceptually-based analytical research to help specify the mechanisms that underlie developmental differences in…

Explores the historical roots of universalistic thinking about children's nature, their needs, and what constitutes healthy development. Considers the opportunities for a new psychology of childhood to be reconstructed in ways that pay more attention to the cultural dimensions, as well as to the socio-cultural process, of the subject. (Author)

Examined the effects of phonological-skill training on consonantal-phoneme deletion and word-reading performance in early and middle adolescent Chinese readers who were literate in English. Found significant improvements in both activities for younger but not older participants, with follow-up analyses suggesting that language-proficiency…
