An 8-week summer institute was conducted in 1967 by the University of Illinois College of Engineering to upgrade the professional competence of 24 high school drafting teachers from 15 states, and to estimate how many of such a group, after study in this and related programs, could successfully move into teaching technical institute level courses in mechanical technology and machine design. The program consisted of 24 class hours weekly in 3 courses: Applied Mathematics for Mechanical Systems, Introduction to Design, and Seminar in Technical Education. Courses were paced flexibly since participants' backgrounds were in education with no engineering sciences and limited mathematics. About l/3 of the enrollees demonstrated enough capability in mathematics that success could be predicted in further study of mathematics or engineering science requiring mathematics. About l/2 handled well the work in advanced production and design dimensioning, and l/3 clearly showed success in work in graphics and analytical statics, fundamental for kinematics or machine design. The seminar elicited group lament that past education courses had left them with little depth in technical subject matter to be taught. There was collective enthusiastic endorsement of the institute and recommendation for its continuance and extension into programs of four summers' duration. Appended are the class schedule, publicity materials, and a list of participants. (Author/JS)
