The study focused on the problem of poor academic performance in elementary schools by examining the relationship between principals' leadership behaviors and student achievement outcomes and the extent to which these behaviors differ according to the poverty and performance characteristics of the school. A review of the effective schools…

This study examined the generality of the logarithmic to linear transition in children's representations of numerical magnitudes and the role of subjective categorization of numbers in the acquisition of more advanced understanding. Experiment 1 (49 girls and 41 boys, ages 5-8 years) suggested parallel transitions from kindergarten to second grade…

Among third, fourth, and fifth graders tested, performance on embedded figures and leveling-sharpening tests correlated with performance on traditional items of class inclusion, suggesting that psychological differentiation is related to reasoning by class inclusion. However, age changes in differentiation do not account for age changes in class…

Longitudinal support was obtained for a positive relationship between cognitive and social development. From a large sample of kindergarteners, three groups of 12 children of comparable age and IQ were selected as displaying substantial, moderate, or no mastery of Piagetian concrete operations. From kindergarten through second grade, the social…

P. M. Lewinsohn has theorized that depression is related to the amount of positive reinforcement that an individual receives. Lewinsohn has supported this model in adults by showing that depression is correlated with an increase in unpleasant activities and a decrease in pleasant activities. This study extended Lewinsohn's model by developing…

These authors cite their own study of the relationship between traditional measures of intelligence and Piagetian measures of cognitive development in support of Glass and Stephens' contention that there are important qualitative differences. They question Humphreys' and Parsons' conclusions on both substantive and factor theoretical grounds. (CTM)

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 longitudinal interrelations among age, visual and auditory short-term memory, and the concrete operational tasks of class inclusion and combinatorial reasoning were investigated over four testing occasions in a sample of 134 students, initially ranging from 5 to 12 years in age. The Piagetian task battery involved placement of colored…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
