A Study of Children's Acquisition of Piagetian Concepts.
Parvand, Mohamad H.
The purpose of this study was to investigate the effects of practice on relevant components of selected operations on a child's ability to conserve substance and weight. A group of 108 children between the ages of five and seven was selected from one school and pretested for conservation of weight and substance. The 48 non-conservers were then randomly assigned to four groups which received between zero and three days practice with the Smedslund training materials. All groups were given a posttest which was identical to the pretest. Using the Signed Rank test, it was found that training had a significant effect on conservation. Significant differences in numbers of conservers assuming "passive-no-guidance,""active-no-guidance," and "active-with-guidance" roles were also found. (MM)
