The Factor Structure of Concrete and Formal Operations: A Confirmation of Piaget.
Gray, William M.
Piaget has hypothesized that concrete and formal operations can be described by specific logical models. The present study focused on assessing various aspects of four concrete operational groupings and two variations of two formal operational characteristics. Six hundred twenty-two 9-14 year old students participating in the Human Sciences Program designed by Biological Science Curriculum Study were the subjects. Two 15-item written tests were given on two consecutive days. Twelve items included drawings, 19 were open-ended, and 11 were multiple choice. For analysis seven items were eliminated because of deviant difficulty indices; the remaining 23 items were subjected to an image analysis with the initial factor matrix obliquely transformed using Hofmann's orthotran. Three factors were exceptionally clean: one including formal operational systematic permutations; one measuring concrete operational addition of increasing asymmetrical relations; and one involving the formal operational logic of making correct implications and denying incorrect implications. Four other factors were mixed within developmental period and across developmental period. Results are discussed relative to tentative support for some of Piaget's logical models, the robustness of Piagetian theory, and the feasibility of a written test of cognitive development.
