An investigation of students understandings of acids and bases using concept maps, multiple-choice tests, and clinical interviews is described. The methodology and resulting analysis are illustrated with two abbreviated case studies selected from the study. Discussion of concept mapping points to how it starkly represents gaps in the understanding…

The conceptual frameworks of Thai children (n=48) related to causes of health and sickness were analyzed using the "Interview-about-Instances" and the "Conceptual Profile Inventory" techniques. The results indicate that Thai schoolchildren hold considerable personal knowledge about the causes of health and sickness that does…

Literacy should not be limited to decoding written text. More broadly construed, education should address the many ways in which experience is represented, the development of cognitive potential, and differences in intellectual proclivities. The object should be cultivation of a broad capacity to construct meaning. (SK)

The conceptual views of homeostasis held by students (n=300) in seventh grade life science, tenth grade biology, and college zoology were examined. A biographical questionnaire, the results from two Piagetian-like developmental tasks, and a concept evaluation statement of homeostasis were collected from each student. Understanding of the concept…

The Educational Attitude Scale was administered to 371 mothers and 23 teachers from 22 schools to determine what they thought about the value of early academics for prekindergartners. Parents had significantly higher expectations, and placed more value on early skill experiences, than did teachers. (SH)

Four experiments examined the possibility that second and fourth graders and college students are sensitive to inference constraint when they make causal inferences and assess their understanding of a story. Inference likelihood and understanding ratings varied with constraint for all ages. Results suggest that comprehension monitoring and text…

Parents of 42 children (ages 2-32) with Lesch-Nyhan disease were questioned concerning the subjects' behavior patterns. Grouping of responses into nine categories of cognitive skills indicated that only one boy showed any significant cognitive impairment. Despite evidence of good cognitive and emotional skills, subjects were academically delayed,…

A study of 13 14-month-old and 12 18-month-old children found that the younger infants relied more on gestures and fussing to express their physical wants, whereas the older infants relied more on vocal responses, especially when clarification of their wants was needed. (MDM)

Based on a two-tiered epistemological model (preliminary physical concepts and emerging mathematical concepts), studied the construction of number among 91 kindergarten students in France, Canada, and the United States. Subjects' cognitive numerical structures were surprisingly similar despite differences in language and culture. (SV)

Examined the relationship between maternal and infant measures of interaction, maternal psychosocial problems, infant cognitive development, and infant attachment security at 18 months of age and child behavior problems at age 5. Disorganized-disorientated attachment status and maternal psychosocial problems were the strongest predictors of…

Tested children's ability to compute perspectives from locational and structural descriptions of scenes. Children from 4 to 10 years of age were given perspective-taking problems that involved abstract multicomponent scenes; responses entailed the reconstruction of alternate views. Four-year olds were unsuccessful; 10-year olds were successful…

This article reviews research on children's development of cognition, memory, and language; development of knowledge about the legal system; developmental and motivational factors influencing children's willingness to make sexual abuse reports in legal settings; reports of abusive touch; and strategies used to prepare children for medical…

This article reviews literature and research on otitis media, focusing on definitions; occurrence, including such influences as age, socioeconomic status, genetics, child care situation, feeding techniques, and sex; fluctuating hearing loss; psychological, linguistic, and cognitive development; and developmental deficits in speech, language,…

Children's analogical reasoning has traditionally been measured by classical four-term analogy tasks or problem-solving tasks. Current theories of analogical development and the evidence on which they are based are reviewed. It is concluded that structural views of analogical development are wrong, and knowledge-based accounts of what develops are…

Tested understanding of correspondence on the part of 2.5- to 3.5-year olds who watched a toy hidden in a model and tried to find an analogous toy in a room. Retrieval scores increased with increasing model-room similarity; were higher for older than younger children; and were affected by object and size similarity. (BC)
