The computerized System of Interactive Guidance and Information (SIGI) is a designated guidance "treatment," clearly defined and specified. It was developed according to an explicit model, derived from a particular rationale for guidance, using modern technology to amplify the practice of career guidance. The current version -- called SIGI PLUS TM -- is being used at more than a thousand colleges and universities, as well as secondary schools, libraries, corporations, community-based organizations, and counseling agencies.
These three interdependent topics are treated in a progression: from a theory of CDM to a rationale and a model for guidance to the design and development of a system. This book weaves together theory (principles, propositions, rationales, and models), research and development. The product of that development, SIGI, helps to define theory, to exemplify it, and to test it.
