Two studies probed 3- to 6-year olds' beliefs about wishing and its efficacy. Study 1 showed that children had considerable knowledge about wishing and an age-related decrease in beliefs about its efficacy. Study 2 suggested that children reconcile beliefs in wishing efficacy with knowledge about mental/physical relations by situating them more…

A schema based view of addition development is compared with Siegler's latest strategy-choice model, which includes an addition goal sketch (a basic understanding of "the goals and causal relations" of addition; Siegler & Crowley, 1994, p. 196). This metacognitive component in the latter model is presumed to develop as a child practices a basic…

This study examined the generality of the logarithmic to linear transition in children's representations of numerical magnitudes and the role of subjective categorization of numbers in the acquisition of more advanced understanding. Experiment 1 (49 girls and 41 boys, ages 5-8 years) suggested parallel transitions from kindergarten to second grade…

Twenty-two children ranging in age from 2 to 3 years were tested on their abilities to apply weight and distance rules to the balance scale. This study was performed to test the prediction that 2-year-olds would be able to understand either a weight rule or a distance rule, but not be able to integrate the two. The sample group was instructed in…

Students using the Science Curriculum Improvement Study curriculum were informally observed to be incapable of defining a system although they could perform related tasks. A study was performed to determine students' understanding of various aspects of systems. (SD)

Shows a cultural influence on children's conceptions of time and motion. Data support the contention that cognitive structure differentiation is primarily a function of experimental rather than innate or invariant factors. (Author/GS)

Individual differences in same-aged children's reasoning about effort and ability, as well as the consequences of different forms of reasoning in actual achievement situations, were investigated. It was hypothesized that different forms of children's reasoning would be related to different (helpless versus mastery-oriented) motivational patterns.…

Although the ideas of Jean Piaget still dominate the field of science education, the range and severity of criticisms has increased progressively. In recent years, the emergence of a different theory of cognitive development has begun. This paper tentatively outlines a Lakatosian Research Programme for the alternative conceptions field. The…

A cognitive training strategy was employed to investigate the nature of development in children's concepts of death. Subjects ranging in age from 3 to 11 years and attending Jewish-affiliated preschools participated in the study. Measures of verbal concept formation, abstract reasoning, general intelligence, and ability to conserve were…

Examines the prediction that the ordinal property of natural number symbols is more easily learned by preschoolers than the cardinal property of natural number symbols. (Author/ED)

Presents a rationale for providing preschool children with experiences related to classification, seriation, and pattern recognition because they are means by which a child can organize the world around him. These are considered to be the early steps in the long developmental sequence leading to logical thinking and reflective observation. (GS)

The goals of the visual arts program of the Attleboro (MA) public schools, its relationship with the rest of the curriculum, and a study of the effectiveness of the program in seventh grade are described. It is suggested that the visual conceptual skills that are developed through the visual arts program are essential to cognitive processes and…

TO VERIFY A PREVIOUSLY OBSERVED DEVELOPMENTAL INVERSION IN PROBLEM-SOLVING ABILITY AND TO EXPLORE PROBLEM-SOLVING STRATEGIES, RESEARCHERS GAVE A SET OF SEQUENTIAL-PATTERN RECOGNITION TESTS TO 316 CHILDREN, REPRESENTING NURSERY SCHOOL THROUGH SIXTH GRADE. EACH TEST CONSISTED OF FINDING TOKENS PLACED BEHIND 5 DOORS IN A PREDETERMINED PATTERN. THE…

This study examined the ability of preschool children to process and use conceptual category information in a disrcimination learning task. A total of 60 boys and girls between the ages of 2 1/2 and 4 years completed a 3-choice discrimination learning task. On each of 12 trials, a child was presented with three magazine photographs: one of an…
