Design of a Computer-Aided Instructional Module for the Navy Occupational Health Information Management System (NOHIMS). Phase I

摘要

The objectives of this study were: (1) to select the best approach for designing a Computer Aided Instruction module for Naval Occupational Health Information Management System (NOHIMS), (2) to specify the data entry and retrieval functions in NOHIMS that constitute the subject matter for a CAI system, (3) to identify the knowledge required by a NOHIMS user, (4) to define the instructional approach and objectives of CAI for NOHIMS, and (5) to determine the specific CAI functions to be implemented and the detailed CAI architecture. The existing CAI software doesn't provide the adaptable, generic capability needed to develop modifiable, interactive instructional software. If the NOHIMS CAI system architecture is to be applicable to a wide range of system applications, the alternative regarded as best is the MUMPS-based ABC system---an Intelligent Tutoring System. ABC consists of three major executable components named ABLE, BILL, and CARLA. ABLE is used to specify the structures (data, file, and procedure) for the application, descriptive textual information needed for instruction, and curriculum structures. BILL is used to specify how the system behaves and to define the content of particular exercises. CARLA delivers instruction in the application's environment according to the specifications provided through ABLE and BILL. CARLA is the only component that needs to run in the application system's environment once preparation of the CAI curriculum, teaching examples, and practice exercises are completed.
