Since the usefulness of the Interservice Procedures for Instructional Systems Development (IPISD) depends on authoring aids which enable personnel to translate IPISD procedures into instructional products, this project examined the feasibility of providing such "how to do it" guidance for the instructional design and development tasks identified for Block II.2-Develop Tests and Block III.4-Develop Instruction. Online authoring aids were developed to be used on the PLATO IV Computer-Assisted Instruction (CAI) system, as well as off-line versions, to assist the author in preparing materials for both CAI and non-CAI delivery of instruction. The three levels of evaluation conducted included an informal evaluation on existing IPISD materials, a formative evaluation of the newly developed authoring aids, and an evaluation of the instructional materials produced. Findings were positive--user acceptance of the authoring aids was high, and the time required for development of test and lesson material was significantly reduced. Based on these findings, the development of such aids for additional blocks of the IPISD model have been initiated. Flowcharts for both the two blocks studied and the authoring aids are provided, and a 97-item bibliography is attached. (BBM)
