Discussion of search behavior in electronic environments focuses on the development of GRIP (Graphic Representor of Interaction Patterns), a graphing tool based on HyperCard that produces graphic representations of search patterns. Search state spaces are explained, and forms of data available from electronic searches are described. (34…

Explains virtual reality as a computer-synthesized three-dimensional environment (cyberspace) in which human participants, appropriately interfaced, appear to be enveloped. Cyberspace in science fiction is discussed; contributions of aerospace and military simulation trainers, digital imaging, and motion picture special effects are described; and…

Describes the system architecture of an intelligent Web-based education system that includes user modeling agents, information filtering agents for automatic information gathering, and the multi-agent interaction. Discusses information management; user interaction; support for collaborative peer-peer learning; implementation; testing; and future…

Examines extent to which assessment of text comprehension involves knowledge of the properties of human cognition and the context of assessment. Shows that assessments of the quality of the answers varied based on the perceived human or artificial source of the answers. Provides copies of experimental questionnaires in the appendices. (DSK)

Discusses the concept of cyberspace, defines three different levels that have been or will be attained, and compares it with mediaspace; examines the concept of virtualization, particularly the virtual library, and defines three different levels; and describes the concepts of cybrarians, cyberocracy, and cyberology. (Contains seven references.)…

Discusses pedagogical issues for intelligent agents to successfully serve as mentors for educational purposes. Examines broader issues about the nature or persona necessary for an intelligent agent as mentor, incorporating usability and human-computer interaction issues such as the anthropomorphic qualities of the agent and the social relationship…

Discusses the importance of positive video game experiences and designs that can create them, including immediacy of feedback, allowing graceful recovery from mistakes, high-quality feedback, and input device mappings. Examines interface complexity. Concludes game designers must treat the interaction between human and video game as a formal…

Explores a user-centered approach to evaluating the Web search engine Inquirus. Inquirus was rated highly by users on various usability measures; all users experienced some level of shift/change in their information problem, information seeking, and personal knowledge due to their Inquirus interaction; and different users experienced different…

This paper is grounded in a large-scale, nine-year research project intended to design, develop, evaluate, and transfer intelligent tutoring systems (ITS) to public schools and workforce development settings. Discussion includes the implementation model; roles and responsibilities of the project team; evaluation results of the tutoring systems;…

The relationship between new technology and learning is gaining increasing relevance in the field of music education (Webster, 2002; Folkestad et al., 1998). However, only a few studies have considered the nature of the interaction between children and musical machines. This article describes an observation study of children aged 3-5 years…

Describes the components and capabilities of expert systems, discusses the use of such systems in library information applications, and outlines research being done in this area. A project aimed at the development of an expert system for referral services is described in detail, and implications for future research are discussed. (CLB)

Proposes a "critical mass" explanation for the diffusion of interactive media, such as telephone, electronic mail, or computer conferencing, within communities. Considers two special characteristics of interactive media: (1) that widespread usage creates universal access, and (2) that use entails interdependence, in which earlier users…

Suggests that insights from other disciplines be considered when evaluating computer-assisted language instruction materials. Issues which need to be considered when evaluating these materials include: design issues, user-machine interfacing, support documentation, screen layout, color and animation, and restricted visual display capacity. (SED)

Examines the characteristics of management information systems and their impact on decisions of senior library managers. The organizational feasibility of such systems is discussed in terms of four key components--economic, technical, structural, psychological--that are related to libraries in general and senior management decisions in particular.…

Investigation of end-user searching at National Library of Medicine reveals that volume of searching is related to convenient placement of terminal; slightly fewer than half of potential searchers search for themselves; practices of pharmacists and pathologists do not differ in important ways; end-user searchers perform simple searches. (86…
