Two experiments investigated the relationship between family size and "theory of mind." Results from an experiment with three- and four-year olds showed that children from larger families were better able than children from smaller families to predict a story character's mistaken (false-belief based) action.

Reports on a study of 198 Canadian children, ages 4-8, on their understanding of the role of evidence on the formation of beliefs. Finds that younger children evaluate opinions based on their own beliefs about the situation; older children tend to ascribe knowledge to others on the basis of evidence available to those others.

Understanding the nature of the 5- to 7-year shift is essential if educators are to help children adjust to elementary school. The timing and quality of this shift is influenced by child characteristics, home environment, cultural context, and previous group learning experience. Since child development depends on children's engagement in cultural…

Examines the benefits of sand play for young children, focusing on areas of cognitive, physical, communicative, creative and social-emotional development. Also discusses the role of the teacher in encouraging children's natural curiosity and exploration with sand play, noting that teachers should observe and interact with children during play in…

Examined the development of proportional reasoning by means of a temperature mixture task. Results show the importance of distinguishing between intuitive knowledge and formal computational knowledge of proportional concepts. Provides a new perspective on the relation of intuitive and computational knowledge during development. (GLR)

This study examined 236 8-year olds from a state with minimal child care standards in an effort to discover possible differences associated with child care histories. Children with more extensive child care experiences were associated with negative ratings by parents, teachers, and peers. (SH)

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)
