Suggests some difficulties and challenges in understanding and teaching Piaget's new theory. Outlines some differences between Piaget's new and standard theories, such as the diminished status of the emergent skills that mark the onset of concrete operational thinking and the perception of achievements in concrete operations as empirical…

Used multiple baseline design with four 6-year-old Latino children to train in class inclusion through counting, feedback, and verbal reinforcers, and in English language skills (of benefit in their own right), over 5 months. Found that post-intervention gains in the two domains were significant and were stable over at least 4.5 months. (KB)

Two studies investigated the functional equivalence of three different scoring systems used to assess the child's ability to understand and carry out multiplicative classification tasks. All three scoring criteria produced reliable and homogeneous tests. Their factor matrices were similar, and the corresponding factor structures were invariant…

This study examined the hypothesis that age-related increases in reasoning ability are associated with the ability to represent relations of increasing complexity, defined as the number of entities related. The study's purpose was to determine the extent to which this ability to process relations with three entities increased between ages 4 and 8…

The effects of instruction in the Piacceleration Program (PXL), a hands on mastery-based program of instruction in Piagetian skills, on the acquisition of skills of classification, seriation, and conservation were studied with 28 Head Start students of Hispanic origin and 28 comparisons. PXL students did perform better on these skills. (SLD)

If, as research suggests, exposing children to two languages and two cultures provides a cognitive advantage, it could be assumed that a child exposed to two languages may be accelerated in a more advanced cognitive stage (as defined by Piaget) than a child exposed to only one language. This study sought to determine when Hispanic children from…
