Instructors are constantly baffled by the fact that two students who are sitting in the same class, who have access to the same materials, can come to understand a particular chemistry concept differently. Variation theory offers a theoretical framework from which to explore possible variations in experience and the resulting differences in…

The application of Piagetian theory to educational practices encounters a series of major difficulties. The main focus of this paper is on the notion of general stages, which has been under attack in numerous studies. Organized in four parts, the paper: (1) discusses the problem of the existence of general stages and of a developmental…

Emphasizes the benefits of cooperation between researchers in developing a comprehensive model of cognitive development that considers the constraints of human brain structures and the interplay of general laws of development and individual differences in developmental pathways within the context of social and cultural environments.

Military and personnel training research addressing individual differences in training environments appears in four general research areas. These include the study of (1) trainee cognitive strategies, learning styles, and sensory modalities; (2) noncognitive characteristics of trainees; (3) aptitude-performance interactions; and (4) the effects of…

Ability to represent life-size space in a small scale was examined by asking 4-year-olds to create a small-scale model of a familiar preschool classroom. Study 1 children with high or low restructuring ability completed the model under guided or nonguided format. Guidance given to Study 2 children emphasized a functionally clustered classroom…

We explored the ''idiothetic'' cognitive structure of RIASEC occupational percepts in a sample of Italian middle and high school students over a one year period, examining the possible bidirectional linkages between cognitive-vocational structure, involvement in career exploration activities, and exposure to authoritative parenting style. The…

Learning differences or disabilities can be best understood and addressed within the holistic/constructivist theory of knowledge construction and the reciprocal evolution of cognitive structures. Learning differences manifest themselves in the spirals of mental structuring activity that guide relational thinking. Such a perspective focuses on…
