Individualized Instruction for Data Access (IIDA). Quarterly Report No. 4.
Drexel Univ., Philadelphia, PA. Graduate School of Library Science.; Franklin Inst. Research Labs., Philadelphia, PA.
A brief summary of the progress and status of the Individualized Instruction for Data Access (IIDA) project is followed by a report focusing on the principles and rules for analyzing a computer search performed using the IIDA software, and adaptation rules for the deferment of error messages in the case of frequent violations of the same rule. The IIDA computer software system consists of four main programs, three in the exercise mode--a preliminary introduction to searching, a practice search exercise, and more advanced training, and one in the assistance mode designed to assist the user in the performance of a search of his own choosing. Twelve principles are enumerated and described for the analysis of such a search: string and cycle analysis, repeated commands, null sets, unused sets, thrashing, dwelling, relevance, print control, use of null sets, time, syntax, and slack and help requests. Diagnostic rules given are concerned with the general configuration of the search and procedural diagnostic rules. Adapting rules deal with the nature of rule adaptation, the assignment of rules to classes, and the evaluation of rule adaptation. Seven references are listed. (CMV)
