Three experiments investigated the developmental progression of reliance on object function versus object shape to extend novel words among 3- and 5-year olds and adults. Findings indicated that children focused on shape, whereas adults focused on function when extending novel words, suggesting a developmental change in the consideration of these…

Argues that Bartsch and Wellman are successful in analyzing natural language to understand the emergence and development of a theory of mind in everyday social interaction. Discusses their delineation of the transition from a focus on desire to a concept of belief, and describes their views on contextual and cultural variables in theory of mind…

Investigated the emergence of class and propositional reasoning skills as a function of the developing ability to coordinate increasingly complex negation and affirmation operations with children from grades 1, 3, 5, and 7. Found that children's reasoning follows a logical development sequence and that different groups of items account for…

Delineates the current consensus regarding the nature and the development of intellectual ability. Examines when one would expect general abilities to moderate the relationship among domain-specific and other processes. Reviews recent studies in which general abilities were used as independent variables or covariates. Suggests that generally,…

Whether "psychometric" and "Piagetian" kinds of intelligence are similar is a question of whether they have similar courses of development with age. When using factor analysis to address this issue, age effects must be eliminated in order to assess relations among measured constructs. Reanalyses of previous results were…

Reports an experimental study of 80 ninth grade biology students randomly assigned to treatment and control groups to determine whether the use of human examples in instructional strategies on Mendelian genetics increases acquisition and retention of genetics concepts. Results indicate that use of human examples in contrast to traditional examples…

Kindergarten (n=30) and grade 1 (n=15) students of contrasting socioeconomic backgrounds were interviewed to assess their knowledge of number word sequences and spatial patterns and their ability to recognize numerals and use counting to establish numerosity of visible and screened collections. Findings indicate greater variation in abilities…

Explores the intuitive understanding of biology that occurs in early childhood and discusses later cognitive changes that occur. Young children possess a vitalistic understanding (e.g. breathing brings power to the body) that becomes mechanistic (e.g. an understanding of the heart and lungs) as they mature. Includes statistical and tabular data.…

Some science educators who are interested in conceptual development have considered the phenomenon of student misconceptions and alternative frameworks. Researchers have used a variety of terms to describe the situation in which students' ideas differ from those of a scientist about a particular concept. This digest was produced to briefly…

To discover the relationship between cognitive development and writing, a means of assessing writing is needed that reflects accurately changes in the way children write as they grow older. This may be accomplished by using Piaget's characteristics of concrete and formal operations. His framework permits general descriptions of thinking, organized…

Reports the design of the "Mechanics Baseline Test," an instrument to assess students' understandings about concepts in mechanics. Discusses how comparisons of test results with extensive baseline data can be used to evaluate instruction at all levels. Includes a copy of the instrument. (MDH)

Cognitive theory and research are relevant to vocational education. Three theoretical perspectives underlie cognitive theory-based curriculum and instruction: information processing, knowledge structure, and social history. A review of these perspectives in vocational curriculum and instruction suggests that instruction supporting higher-level…

Sex differences on Perry's stages of epistemological development were investigated in a study of 100 freshmen (50 men and 50 women) at a large midwestern university. A semi-structured interview probed six domains related to Perry's theory, including the role of the learner, instructor, and peers in the learning situation, the question of…

Reviews research on (1) schemata acquisition while learning mathematics and techniques for detecting schema in mathematics learners; and (2) assessment of the distribution of cognitive resources while learning mathematics that lead to the design of instructional techniques to facilitate schema acquisition. (26 references) (MDH)

Videotaped interviews of 29 Australian students from grades 1-3 were analyzed to assess and compare the processing loads of mathematical representations and strategies used by teachers and children to learn the concept of place value. Results indicated that some representations and strategies impose an unnecessary processing load that can…
