This Programming Design Guide (PDG) was developed to permit the offline Job Aid for Selecting Instructional Setting, which is one of 13 job aids presently available for use with the Instructional Systems Development (ISD) model, to be available in an inquiry-type, online version. It is intended to provide computer programmers with all of the guidance necessary for them to implement the offline job aid on their computer system. The resulting online program is designed for use by instructional development personnel to assist in the selection of the appropriate instructional setting for each critical task within a Military Occupational Specialty (MOS). Inasmuch as the PDG will be used as a guide for programming on a number of computer systems which employ different programming languages, the guide is written in a program design language (PDL) format rather than in any specific programming language. The PDL is a pseudo-computer language which is used to describe the design specification for an interactive computer program to assist in the selection of instructional settings. (Author/LLS)
