Industrial management concepts in the taxonomy of the Industrial Arts Curriculum Project (IACP) at The Ohio State University were the focus of this study. The purposes were: (1) to determine the associative meanings which were held by manufacturing management personnel for 14 selected management concepts, (2) to determine the principal relationship of word association responses to each management concept, and (3) to compare these principal relationships to the concepts in order to determine their content validity. Word association data were collected in written form by use of a controlled, continued word association technique. The purposive sample of respondents was composed of 27 employed manufacturing management personnel. Responses were subjected to an inspective and statistical analysis. Relatedness coefficients and a hierarchical factor analysis of the coefficient matrix were utilized. Twelve stimulus words were judged as valid for continued use in the IACP curriculum taxonomy; two words were judged as not valid for continued use. The associative meanings of each of the stimulus words differed from all others as indicated by the range of Relatedness Coefficients by .0022 through .869. It was concluded that each stimulus represented a distinct concept for the sample of respondents. This Ph.D. dissertation was submitted to The Ohio State University. (EM)
