Within a setting of dynamic rather than static knowledge, the academic structuring of disciplines begins to lose meaning. Interdisciplinary courses are one result of this perception of knowledge. A polydisciplinary approach, however, would be a more accurate construct of reality. Given the following four aspects of a polydisciplinary approach to the study of man--environment, actions, knowledges, and pulsating growth--a three dimensional matrix described by the first three aspects, of which the fourth is an integral part, is possible. Each aspect breaks down into small parts: action consists of doing, deciding, dreaming, and discovering; knowledge consists of sciences, technics, humanities, and praxis; and environmental areas consist of socio, psychic, abiotic, and biotic. The interrelatedness of the parts becomes multifaceted in a three dimensional matrix. This approach is action-oriented in that it relates to existing situations that face man and involves an experiential study of the interactions of man and his activities. (Author/JH)
