| Abstract: | This paper describes the development of the Information Processing Taxonomy (IPT) Model which models children's thinking at different hierarchical levels. The main features of the Model consist of retrieving information from external memory and primary and secondary productions of Type A and B information. These features constitute the components of different levels of thinking which could be used to confirm and describe the children's cognitive processes. Examples are shown to illustrate how the Model could be used to construct test items at different levels on the basis of these features. The Guttman procedure was applied to test the consistency of the hierarchical nature of the Model. Results show that the items constructed using the Model were scalable. |
