Examined the cognitive and social complexity of the play of disabled children enrolled in integrated early childhood programs and their interaction with teachers. Found that teachers were more likely to support the cognitive aspects of children's play than the social aspects, despite their belief that disabled children lagged behind their…

Verbal and nonverbal classification tasks were administered in Spanish and English to 30 bilingual children, aged 6-7. Results indicate the positive influence of bilingualism on cognitive development and support a model in which bilingual children construct two representational systems--one, nonverbal and universal across languages; and a second,…

Seventy-five 4-, 6-, and 8-year olds participated in a study examining the relationship between children's awareness and use of strategies for self-control. Knowledge of strategies was more highly correlated with process than with performance, and the relationship between knowledge about strategies and actual performance increased with age. (AA)

This overview reviews a program of interlinked cross-sectional and longitudinal investigations of the nature of cognitive development in infants and young children with Down's Syndrome. The research falls into three groupings: object concept studies, operant learning experiments, and IQ studies. Early results suggest a common learning style which…

Examination of the treatment program for learning-disabled adolescents at McGill-Montreal Childrens Hospital Learning Centre (Quebec) suggests intervention can mitigate effects of even severe learning disabilities if it addresses consequences of prolonged stress and failure and affective and social competence as well as cognitive and academic…

Strategies for teaching second-language learners are reported that facilitate the acquisition and development of several linguistic, academic, and conceptual skills and abilities, including basic skills. Examples include storytelling, shared literature, advanced organizers and semantic mapping, frames as cues, conjoining and embedding exercises,…

Graphical representations of geometrical objects from high school textbooks are categorized according to the implicit conventions underlying their display. The fact that specific illustrations can lead to students' misconceptions about geometric objects is analyzed in relationship to the principle of parallel projection with implications for the…

Describes a process approach to teaching and learning in preschool settings. The approach uses child-initiated play in a prepared environment, and encourages children's formation of symbolic mental representations through social interaction and mediation. Offers guidelines for the implementation of the process approach. (MM)

This article, the fourth in a series on work conducted at the Texas Center for Educational Technology and the University of Texas, discusses evaluative measures needed to assess the improvements that educational technology may have on students' problem solving, critical thinking, and content-level abilities. An annotated list of standardized tests…

Reports a study designed to identify 9 and 11 year olds' ways of drawing nets of solids and to provide opportunities for them to reflect on their models in whole class discussions. Results indicated that children's views of solids' nets progressed from more global and holistic to more quantitative and analytic. (MDH)

Reviews the history of the concept of function, looks at its relationship with other sciences, and discusses its use in the study of real world situations. Discusses the process of constructing mathematical models of function and emphasizes the importance of the roles of the numerical, graphical, and algebraic representational forms. (MDH)

Reviews recent research in the area of mathematical understanding and compares and contrasts it with a model formulated for the growth of understanding. Uses the analysis of a transcript from an interview with an eight-year-old boy to illustrate the power of the model to describe and map the growth of his mathematical understanding. (18…

Discusses the use of feedback from students and the analysis of students' error patterns to understand why students develop misconceptions in mathematics. Looks at learning vis-a-vis the abstract nature of mathematics and the students' cognitive development. (MDH)

To evaluate the part that nascent skeptical doubt plays in shaping adolescent social-cognitive development, 61 high school students clearly classified as in concrete or formal operational stages of cognitive development completed a measure of epistemic stances. A relationship was found between cognitive and epistemic development. (SLD)

Forty children were divided into four groups and administered the Tower of Hanoi puzzle using static and dynamic approaches. The benefits of age and ability were indicated by significant improvement from the general failure of the four- to five-year olds to the success of the majority of the high ability seven- to eight-year olds.
