In the past three years, higher education institutions have made a number of moves to secure their critical systems and protect their users, resulting in a marked change in the techniques used to combat security threats. Today, continued progress may depend on the development of an enterprise IT security program. (Contains 10 notes.)

This article describes the stages in developing a special education expert system: orientation, development of a theoretical framework, generation of content for the system databases, and checks for consistency and logic/revision. It explains the synthesis and application required to build the content for the system and discusses typical problems…

Discusses the special information needs of the building industry, attributes of existing expert systems that support building design and construction, and current research to further develop the application of expert systems to this area. An annotated listing of related expert system developments is appended. (49 references) (CLB)

Describes generative learning environments for teaching mathematical problem solving that were developed at the Vanderbilt University Learning Technology Center. The theoretical framework is discussed; design principles are explained, including a video-based presentation format; and the use of videodisc and hypermedia is discussed. (37 references)…

The PRODIGY/EBL system [Minton88] was one of the first works to directly attack the problem of strategy utility. The problem of finding effective strategies was reduced to the problem of finding effective rules. However, this paper illustrates limitations of the approach. There are two basic difficulties. The first arises from the fact that the…

Attempts to train learning strategies have not produced marked or lasting increases in academic IQ, probably because current training models fail to recognize the evolutionary nature of strategies acquisition. Empirical and theoretical evidence supports an incidental learning model, which engineers the instructional environment following study…

The literature on instructional design argues that curricula, educational materials, and instructional strategies are best created using a systems approach, and models for the systematic design of educational programs have proliferated over the past decade. However, these models are prescriptive and not based on research into how designers…

Presents results of five experiments on human information-seeking behavior in different online information-seeking environments which studied search strategies and assessed information value in realistic search environments. A conceptual model of how humans value information is presented. Empirical and modeling results are considered for…
