4 Information Access Instruction (IAI ): Design Principles Zorana Ercegovac

This article proposes four design principles-The User, Active Learning, Con­ ceptual Model of Teaching, and Modularity-as a conceptual framework of an 4 Information Access Instruction (IAI ). These principles, when put in practice as specific guidelines, seamlessly link information sources together, regardless of their implementation medium, information structure, or interface style. Examples are drawn from a section of a four-unit elective undergraduate course taught in the Department of and Information Science, University of California at Los Angeles.
