Dimensionality, Scoring, and Related Problems in Adaptive Testing.
Abstract
Major efforts of the project fall into four categories: Investigations were performed on the relationship between the dimensionality of a dataset and its underlying cognitive processes. Two approaches for diagnosing erroneous rules of operation were developed; an 'error vector' system for constructing error diagnostic programs for signed-number arithmetic and fraction addition problems, and a series of logical statements for constructing diagnostic programs for fraction problems; To circumvent the problems encountered in the construction of error diagnostic programs, two indices based on deterministic Guttman theory were formed and used to detect aberrant response patterns; and The necessity for dealing quantitatively with variations in errors and changing rules of operation led to the investigation of probabalistic models for error diagnosis based on item response theory.
