Updating information on various developmental efforts in computer-based training, this report provides information on new developments that may have implications for Navy training. Although projects in the military services are emphasized, major developments in the civilian sector are also reviewed. The range of activities emphasizes the use of computers for teaching and includes a wide variety of computer aids to instruction. Information for this report was gathered from reports supported under a Navy contract and from a continuing survey of other developments in computer-based instruction. It is organized under five major topic headings: (1) military activities, (2) civilian activities, (3) systems developments, (4) current issues in instructional design, and (5) state-of-the-art and Navy training needs. An overview is provided for each of the major topic areas as well as for many subtopic areas. A supporting bibliography is also included. (Author/DGC)
