Autoinstructional Aids Computer Assisted Instruction Dial Access Information Systems Educational Technology Information Retrieval The basic objective of the electronic dial access information retrieval system (DAIRS) is to serve individual students in semi-private listening or viewing situations with a kind of "non-book" library resource almost instantaneously available at the student's option. DAIRS represents the combination of two long established communications techniques--magnetic tape recording and replay devices and telephone dialing switching devices. Only a handful of DAIRS installations offer the random access feature, as the technology for this is both primitive and expensive. Variable video access is also still in the developmental stage. The future will probably bring a combination of the various attributes of a DAIRS system related to multi-branching systems of logic in computer assisted programed instruction. Many schools are already experimenting with one form or another of a DAIRS system, but before the full potential of this or any other technological innovation may be realized a thorough analysis of educational objectives and procedures is in order.
