This document reports on the initial phases of an ongoing research project designed to develop a classification of literature citations that would indicate the subject-matter expertise needed by those who study, teach, conduct research, and make decisions in the field of study known as vocational education. A three-dimensional matrix was proposed, breadth of which was indicated through the interaction of practices and foundations and depth of which reflected the prioritized listings of paradigms at each intersection point. Comments about and reactions to the initial matrix were received from 140 vocational leaders across the United States and were used in designing a final matrix or classification of literature entitled "A Classification of Paradigms in Vocational Education Literature by Practices and Foundations." Definitions were constructed for the five practices (aims and policy development; administration, supervision, and organization; curriculum development and evaluation; instruction, guidance, and tests and measurements; research) and the six foundations (historical, philosophical, psychological, societal, economic, scientific). Criteria for selection of literature citation paradigms were identified, and an identification and evaluation instrument was developed. The steps in manually and electronically searching vocational education literature and subsequently classifying the literature citations into practices and foundations were also identified. (YLB)
