2. 1. A Facet Model of the Logical Operational Structures of Piaget's Theory : Guttman's Facet Design applied to Piaget's Theory

   Author : Barbro Bergling; Siv Fischbein; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; facet design; Piaget; operational thinking; Rasch; partial credit model; hierarchical model; psykologi; Psychology;

   Abstract : This thesis explored whether the complex structure of Piaget's theory of operational thinking could be synthesized into a facet model by means of facet design. The aims were: (1) to deduce from detailed conceptual analyses of 12 of Piaget's classical experiments the essential parts of the operational structures (Study I); (2) to explore the internal structure of his constructs in terms of a mapping sentence (Study II); (3) to study the hierarchical structure of the interrelationships between the constructs (Study III); and (4) to apply the facet model in the development of test items (Study II and IV).
