As early as July 1974, the System of Interactive Guidance and Information (SIGI), a computer-based aid to career decision making, had been identified for possible use at the National Technical Institute for the Deaf (NTID). A task force that intensively studied SIGI and its potential for use within NTID recommended that it be brought to NTID. For its successful implementation, the task force recommended certain support services such as a counseling coordinator, a resource assistant, and a research associate. During the three years that SIGI has been in use at NTID, several different implementation strategies have been tried, including totally independent student interaction, use during the Summer Vestibule program, SIGI as a requirement of a career decision-making class, career counseling, pairs of students going through SIGI together, and SIGI as extra credit in other courses. Results of evaluation of SIGI's effectiveness indicated that students and career counselors reported very positive feelings about SIGI's potential use at NTID. Recently, development of a computer program to summarize data from a group of students has been undertaken. The data collection option could be used to study students' comprehension and the use of the various subsystems and allow for comparison of NTID users and normal hearing students. (YLB)
