The Navys Training Analysis and Evaluation Group TAEG conducted an empirical study to determine if measures of training effectiveness or training efficiency were differentially related to the method of instruction used to train Navy technical school graduates. Also investigated were the interrelationships between methods of instruction, ability levels of graduates and the types of tasks taught in the technical schools. Since the same content was not taught in courses conducted under each method, it was necessary to equate the content of the 20 courses i.e., tasks taught to a common base so that appropriate comparisons could be made. For this purpose a generic task classification system was developed. School achievement and job performance measures obtained on over 5000 technical school graduates served as the criterion variables. This paper presents the background for and design of the study.
