Item Construction and Psychometric Models Appropriate for Constructed Responses.
Tatsuoka, Kikumi K.
Constructed-response formats are desired for measuring complex and dynamic response processes that require the examinee to understand the structures of problems and micro-level cognitive tasks. These micro-level tasks and their organized structures are usually unobservable. This study shows that elementary graph theory is useful for organizing these micro-level tasks and for exploring their properties and relations. The proposed approach uses deterministic theories, in addition to graph theory, and Boolean algebra. This approach enables researchers to better understand macro-level performance on test items. An attempt to develop a general theory of item construction is described briefly and illustrated with the domains of fraction addition problems and adult literacy. Psychometric models appropriate for various scoring rubrics are discussed. There are 40 references. Six tables and four figures illustrate the discussion. (Author/SLD)
