Extensions of man and human development

Abstract

The ultimate aim of education is the construction of wisdom which is the highest level of human development. Wisdom can hardly be achieved free of contents. As the scientific and technological knowledge explodes new subject matter areas are emerging. Also the body of knowledge within the present ones is getting bigger and larger. Since the overlaps between the contents of different domains are also intensifying there is a need to refine the information content of curricula. The conversion of information into instructional messages is a necessary condition but not sufficient. There has to be ways and means for its handling with care. It takes media-extensions of man- to store, to multiply, to transport, to transform if needed and to retrieve the codes of messages. The purpose of this paper is to sustain the system characteristics of instructional practices with a special emphasis on media component. The conclusion at the beginning is that media can replace neither any other component nor the whole instructional system even within an infinitesimal span of time. All components are mutually interdependent without losing their unique attributes. © 2018 Elsevier B.V., All rights reserved.
