Peer reviewedRhodes, Robert L.; Whitten, Janice D.; Copeland, Ellis P. – Journal of Experimental Education, 1997
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)
