Abstract	The purposes of this study were (1) to develop a requester-to-system Computer Assisted Instruction (CAI) interface with a batch processing information retrieval system, (2) to compare users' satisfaction with retrieval services between the experimental CAI training approach and the traditional person-to-person negotiation process, and (3) to test the ability of the experimental CAI interface to impart a knowledge gain of literature-searching skills related to the Educational Resources Information Center (ERIC) information base. Sixty subjects were randomly assigned to 2 treatment groups: 30 obtained computer search services by the traditional method and 30 were placed directly in charge of formulating their own search strategies via the CAI training package. Data from 58 subjects were suitable for analysis. The satisfaction scores and search precision ratios analyzed indicated that the treatment groups did not differ. However, novice users of the CAI package acquired significant gains in knowledge relative to the use of the ERIC data base. It was concluded that the use of a specially created CAI telecommunications interface system is a viable alternative to search negotiations which require the services of a professional staff.
