Examined the relationship between 7-, 9-, and 11-year old children's performance on a battery of selected Piagetian measures and on a proportional reasoning task. Found a strong relationship between stage level and (1) the complexity of hypotheses used, (2) the use of the proportional hypothesis, and (3) the overall use of logical hypotheses. (HOD)

Investigated secondary-level students' (N=66) understanding of three-dimensional structures in biology. Results suggest that student performance is highly correlated with age, scientific ability, and sex. Suggestions for instructional improvement in spatial relationships are offered. (ML)

Identified some of the misconceptions held by secondary science students (N=232) related to selected ecological concepts and generalizations. Lists the alternative conceptions expressed by these students on food chains and energy flows and pyramids. Offers perspectives on dealing with the sources of the misconceptions. (ML)

Assesses the influence of grade and reading competence on inner-city Black children's sequence memory and use of organization in recall. Suggests that primary teachers should shift from literal decoding practice to providing semantic organizers and emphasizing interrelationships between words. The development of such basic cognitive skills…

This study explored questions about the effect of lesson structure and cognitive development on science achievement of 42 students in grades four and five in British Columbia. Increased lesson structure did not significantly increase achievement, and interaction effects were generally nonsignificant. Conservation ability significantly affected…

Demonstrates how three- and four-year-old children's (N=20) learning of a completely novel route across a city district is enhanced by an accompanying adult making the child aware of potential landmarks. The importance of permanent/ephemeral landmarks in the child's verbal and modelled-map accounts of the route and educational implications are…

Traces history of instructional technology, including Skinner's work, Gagne's task analytic approach, and contemporary efforts associated with the cognitive revolution. It is suggested that an understanding of cognitive development improves earlier approaches by adapting them directly to students' cognitive development levels. Recent instructional…

Examines possible correlates of difficult temperament by testing 152 adopted and 120 nonadopted infants at 12 and 24 months. Finds no significant relationships between parental reports of difficult temperament and other aspects of infant development, the home environment, or parental personality. Questions the utility of the construct of difficult…

Conceptual analysis of two perspective-taking tasks identified a number of subtasks calling for equivalent operations of social reasoning within tasks of different content. Subtasks hypothetically formed a logical and developmental sequence of abilities required for decentering. The developmental significance of the hierarchy was tested among 121…

Argues that the second language acquisition process involves two models, providing complementary accounts of different components which could be combined. An integrated model is proposed that would carry the acquisition-learning distinction of the Monitor Model while including the Neurofunctional Theory, which uses the distinction to describe the…

This article reports the evaluation of a cognitive education course designed for inmates in Canadian federal penitentiaries. Reports from school instructors indicate that participating inmates showed improvement in their ability to communicate and discuss ideas and were more able to stop and think before acting on a problem.

This investigation of the development of young children's concept of evaporation examines their intuitive explanations of real world events involving evaporation. A study of the effects of providing evidence contradicting their explanations and of directing their attention to relevant situational features provides insight into the development of…

Examines biological and environmental determinants of creative/divergent thinking in light of two studies--one showing an inverse relationship between serum uric acid and divergent thinking and one showing a positive correlation between family size and creativity in upper socioeconomic status groups. Outlines classroom practices that promote…

Perry's scheme of intellectual and ethical development was examined for sex differences with respect to three areas of identity concern: occupational choice, interpersonal relationships, and sexual identity. Regression analyses revealed patterns in which male personality processes focused upon occupational issues while female processes focused…

"Music Video 454," a course surveying the history, business, and aesthetics of the most important force in both music and television, is described. The instructors teach students to analyze videos--aesthetically and sociologically, and hope to enhance their career prospects. (MLW)
