This survey of 120 school psychologist trainers found that (1) there is widespread familiarity with dynamic assessment as a model of cognitive assessment; (2) few trainers are actually using the procedures; (3) most trainers do not mention it in their courses; and (4) trainers see the model's primary asset as its focus on learning processes rather…

Reports a study designed to identify 9 and 11 year olds' ways of drawing nets of solids and to provide opportunities for them to reflect on their models in whole class discussions. Results indicated that children's views of solids' nets progressed from more global and holistic to more quantitative and analytic. (MDH)

Reviews recent research in the area of mathematical understanding and compares and contrasts it with a model formulated for the growth of understanding. Uses the analysis of a transcript from an interview with an eight-year-old boy to illustrate the power of the model to describe and map the growth of his mathematical understanding. (18…

The pencil-and-paper assignment "Represent water in its three states using a model" was given to pupils (n=227) from eighth to twelfth grades. The findings show that the dominant model used was the space filling type; movement of particles was indicated by a minority of pupils; size of the model changed when drawn in different states.…

Two studies of the cognitive processes involved in online document-based information retrieval were conducted. These studies led to the development of five computational models of online document retrieval which were incorporated into the design of an "intelligent" document-based retrieval system. Both the system and the broader implications of…

Focuses on the responses of elementary school children (N=336) to an "Awareness of Technology Survey" question intended to explore how they would begin the technological problem-solving process. Contains 29 references. (DDR)

Explains why metaphors are important design elements in multimedia learning environments. Describes a model developed for levels of metaphor mapping which is oriented toward a cognitive engineering approach for describing aspects of user interfaces. Shows the extent that the didactic dimensions of width and depth of metaphors be taken into account…

Data from a study of learning conducted with 26 seventh and eighth graders are used to show the highly heterogeneous and contingent nature of students' responses to lever problems. A framework is proposed to explain variations in cognitive performance across situations and to critique some of the assumptions underlying assessments. (SLD)

The verbal overshadowing paradigm was used with 167 undergraduates to determine whether performance across all items on Raven's Advanced Progressive Matrices was dependent on the same cognitive processes. Results clearly indicated that a subset of items was dependent on visuospatial processes, while another subset required verbal-analytic…

Highlights the strengths of the Halberstadt et al. contribution to the literature on social-emotional development. Discusses three issues relating to their model: (1) the inseparability of cognitive representation in both emotional and social functioning; (2) the role played by context; and (3) the significance of goals in any construct involving…

Advocates artificial neural networks as models for cognition and development. Provides an example of how such models work in the context of a well-known Piagetian developmental task and school science activity: balance beam problems. (Contains 59 references.) (Author/WRM)

Studies on human and animals shed light on the unique hippocampus contributions to relational memory. However, the particular role of each hippocampal subregion in memory processing is still not clear. Hippocampal computational models and theories have emphasized a unique function in memory for each hippocampal subregion, with the CA3 area acting…

The current study developed a new paradigm to determine the age at which children begin to show the self-reference advantage in memory. Four-, 5-, and 10-year-olds studied lists of colourful object pictures presented together with self or other face image, and participants were asked to report aloud "who is pointing at the (object)."…

This paper describes the conceptualizations, or mental models, of the nature of the bonding and structure of metals of a group of U.K. college students. It is suggested that these mental models may be understood in terms of the students' prior learning about covalent and ionic bonding, and the prevalence of a common alternative conceptual…

The number of children and adolescents accessing the Internet as well as the amount of time online are steadily increasing. The most common online activities include playing video games, accessing web sites, and communicating via chat rooms, email, and instant messaging. A theoretical framework for understanding the effects of Internet use on…
