Twenty-three instructors participated in an 8-week summer institute to develop their technical competency to teach the second year of a 2-year Technical Education Computer Science Program. Instructional material covered the following areas: (1) compiler languages and systems design, (2) cost studies, (3) business organization, (4) advanced programming, and (5) operating systems. In evaluating the results of the institute, the Programmer's Aptitude Test by the Psychological Corporation, New York, New York, was given at the beginning to establish each participant's aptitude in areas of numeric, verbal, and abstract reasoning relevant to programming. In addition, pretest and post-test scores were determined in the following areas: (1) business organization, (2) cost accounting, (3) systems, (4) COBOL, and (5) FORTRAN. Class schedules, textbooks, and a teacher-participant evaluation are included. Success of the institute led to the following conclusions: (1) Competent data processing and computer programming instructors, including teachers from other disciplines, can be trained in two summer institutes, and (2) Their success can be predicted from aptitude tests. Periodic follow-up instruction to teachers is recommended. Phase I of this study is described in ED 016 066. (MU)
