A Note on the Factor Structure of Some Piagetian Tasks.
Lawson, Anton E.; Nordland, Floyd H.
Some evidence supports the hypothesis that formal operational reasoning ability (at least that measured by Piagetian tasks) is a unified process. The purpose of this research was to determine: (1) if conservation tasks, such as conservation of number, liquid amount, weight and volume, are unifactor; and (2) if conservation tasks form a scale of early concrete to early formal reasoning ability, would analysis yield two principal components - a concrete component and a formal component. Ten Piagetian tasks were administered to 96 seventh-grade urban science students. The factor structure of the tasks was determined using principal components analysis. The analysis did reveal two components. One component was identified as an early concrete operational component. The other component was identified as an early formal operational component. The results were consistent with Piaget's theoretical discussions about what the tasks measure and represent a factorial validation of the tasks. This indicates that the tasks can be used in a meaningful manner to measure concrete and formal operational thought. (Author/DC)
