Reviews the objectives of laboratory work in chemistry education, current laboratory practice, and factors likely to impact on the nature of laboratory work in the future. Proposes that more investigation-style laboratory work be provided in order to foster the development of students' investigation skills. (Author/MKR)

Examined the cognitive development of 79 surviving high-risk, low birth weight children at 1, 2, and 3.6 years. Found that children at high biological risk were able to catch up on their cognitive delay in highly stimulating home environments; those at both low and high biological risk in less stimulating home environments showed a decline in…

Examines the question of whether to make computers a part of the early childhood curriculum. Discusses the contribution of computers to children's development, focusing on the role of computers and related technology in benefiting children with disabilities and facilitating inclusion. Discusses ways of adapting technology to make it…

Cognitive development research can be applied to the learning of a second language, resulting in a view of language learning as the acquisition and development of expertise. From this framework, two processes are viewed from within this framework for learners of English: learning vocabulary and learning discourse and story. (Contains 10…

Presents the use of manipulatives in the three stages of concept learning called concrete, bridging, and symbolic. Examines the three stages in developing the concept of rounding two-digit numbers. (MDH)

A literature review identified behaviors representative of the normal stages of communication, cognition, and vocalization in children's prelinguistic period. Results were organized as a checklist for assessment of at-risk infants. The checklist is recommended for monitoring infant development, supplementing formal screenings and diagnostic tools,…

A longitudinal study of 2,165 college students at 4-year institutions suggests that students' precollege traits, quality of academic effort in college, and faculty and peer interactions were more influential on learning and student perceptions of cognitive development than institutional characteristics and environment. A resulting causal model is…

A model of transformational change in education is presented and implications for guiding students to higher levels of communication, critical thinking, problem solving, interpersonal relationships, and creativity are explored. (AEF)

Assessed the beliefs of first, third, and fifth graders about their ability and achievement and their motivational responses to challenging puzzles. Suggests that individual differences in children's cognition about ability and achievement are related to their motivational responses throughout the school years. Points out ways that these…

Examines invented spelling as a stage of progress in children's writing growth. Suggests that children generally understand consonant sounds first. As a consequence, they start invented spelling often omitting all or most vowels. Gradually, as children make the transition to conventional spelling, vowels are added. Proposes ways to facilitate…

Evaluated the development of 44 children adopted from Romanian orphanages. Adoptive parents described their children twice, using the Revised Denver Prescreening Developmental questionnaire when they first met the children, and again at approximately 11 months postadoption. Showed that progress was equal across areas, and that, on average,…

Claims in "The Bell Curve" that Head Start and other early intervention programs are a failure and a waste of funds depend on a notion of cognitive ability reduced to IQ. They ignore other studies that demonstrate the success of such programs and that, consistent with Piagetian views, recognize the interrelationships of cognitive,…

This article focuses on a change affecting Spanish in contact with English in the United States: simplification and loss of subjunctive mood morphology. Analysis of conversational data from 17 Mexican American bilinguals representing 3 immigrant groups living in Los Angeles reveals a reduced inclination for the obligatory use of the subjunctive in…

Sixty-seven students participated in a study that used path analysis techniques to test a hypothesized structural model of direct and indirect causal effects of students variables on science process skills. Academic ability, biology knowledge, and language preference were found to have significant direct effect, whereas cognitive development,…

Examined children's use of the representativeness heuristic with two types of decision problems adapted from research with adults--standard representativeness problems and conjunction fallacy problems. Findings on both problems indicate the use of decision heuristics in the early grade-school years, and suggests these should be the years for…
