The relative development of Piagetian concrete logical operational abilities was investigated in Mexican American and Anglo American children. Performance was assessed on eight classification tasks and three forms of transitivity, measuring seriation skills. One phase of the study compared the performances of 30 Anglo and 30 Mexican American…

Piaget's model of children's conceptual learning and development was compared with Klausmeier's Conceptual Learning and Development (CLD) model in a longitudinal study. The CLD model suggests four successive levels of concept learning: (1) concrete--recognizing an object which has been encountered previously; (2) identity--recognizing a known…

The Conceptual Learning and Development (CLD) Model specifies four levels of concept attainment (concrete, identity, classificatory, and formal) and three uses of concepts (problem solving, subordinate-supraordinate, and principles). Longitudinal and cross-sectional studies of concept attainment may be conducted. The results of this study of 300…

During the first months after birth, a child's functions begin to emerge. By age three a child is expected to have mastered the basic tasks of (1) good vegetative functioning (management of drives and impulses involved in eating and elimination), (2) perceptual organization and familiarization with the home environment and skills to orient to a…

Developed by professional educational staff, the curriculum of developmentally sequenced objectives for preschoolers (SOP) is designed for use in infant stimulation programs, for preschool training for all levels of retardation, with severely and profoundly retarded school age children, and for trainable and educable children during the earlier…

A case study of a pair of extremely deprived twin boys focuses on their verbal communication. Talkativeness alone was not regarded as a measure of intelligence, but attention was paid to the less talkative twin's greater use of imaginative speech. Speculations are made on the evolutionary role of creative speech. (IS)

Guided by a conceptual model linking discrepancies between parent and adolescent developmental expectations and adolescent adjustment and the quality of the parent-adolescent relationship, this study examined adolescent and parent beliefs about the age at which specific competencies should appear. Developmental timetables were grouped into…

Presents a study to examine the effects of a verbal teaching strategy versus a strategy providing instruction using activities and manipulatives in four seventh grade earth science classes with students of varying cognitive abilities (n=83). Results indicate that students with more cognitive structures perform better and that using manipulatives…

A study examined the strategies and processes used by a sample of 33 Argentinean adults with little school experience to solve problems and acquire knowledge at work.

To test whether gains in cognitive development can be accelerated, an intervention model was used to give pupils special lessons in science, using ideas of cognitive conflict, metacognition, and bridging in the context of formal operations. Found that intervention led to substantial and long-lasting increased achievement in science, mathematics,…

College students are continuously engaged in attempting to successfully pass courses, fulfill degree requirements, and plan for their future careers.
