Aimed at improving officer education through the use of modern technology, a two-pronged computer-assisted instruction (CAI) effort was initiated. CAI techniques and methods utilized in the dual projects (CAI-Teletype and CAI 1500) are discussed under three categories: computational, non-computational, and computer management of instruction. Courses in science, engineering, and naval science were developed and tested in the CAI-Teletype Project which then went operational with 125 teletype terminals accessing a Honeywell 635 computer system. The CAI-1500 Project featured sophisticated student terminals and utilized the IBM 1500 Instructional System in a more extensive, more tutorial manner aimed at replacing parts or all of conventional instruction in selected situations. Instructional modules were developed for four academic courses: General Chemistry, Modern Physics, Naval Operations Analysis, and Basic Russian I. (Author/MC)
