Abstract:

This report describes developing the technology necessary to conduct cost effective and efficient validations of the sequencing of instruction used in the training of military occupational specialties. The specific objective was to validate the hierarchical ordering of task domains. A total of 317 subjects were tested on two algebra skill domains. Latent structure techniques recently were used to validate the hypothesized ordering between domains. The first step in the analysis was to construct a set of models representing hypotheses about the tasks under examination. The models developed for use in the present analysis assumed three basic classes of individuals for tasks in an hypothesized domain. These classes included masters of the skill represented in the domain, non-masters, and individuals in transition between non-mastery and mastery. Non- masters were characterized as failing all items in the domain, and masters as passing all items. Transitional individuals were assumed to respond inconsistently in a manner congruent with the assumption that they were still in the process of acquiring the concept or rule underlying mastery of the tasks in the domains under examination.
