This article proposes a mathematical model of Intelligent Tutoring Systems (ITS), based on observations of the behaviour of these systems. One of the most important problems of pedagogical software is to establish a common language between the knowledge areas involved in their development, basically pedagogical, computing and domain areas. A…

This paper reflects a multi-year collaborative effort between the New Media Consortium (NMC) and Griffith University to help inform Australian educational leaders about significant developments in technologies supporting teaching, learning, and research in tertiary education. The research underpinning the report makes use of the NMC's Delphi-based…

This study focuses on how to support students who have to work together in small groups, and who do not know each other, in performing grounding discussion. It compares two different implementations of a script, one using a structured interface, one using a textual instruction, on students' discussion behavior. The experiment involved two…

With the introduction of the digital medium, an abundance of content previously obtainable through other media became available in digital form. Digital delivery implied the necessity for some kind of content modification dictated by the specific characteristics of the digital medium. The situation is further complicated by the convergence of…

Discusses the use of interface metaphors in computer system design. Describes empirical research that shows users can experience cognitive dissonance with metaphors and suggests that the concept of a logical analogue rather than that of a metaphor should guide system designers. (Contains 66 references.) (LRW)

This article discusses the pros and cons of open source software, such as Linux. It asserts that despite the technical difficulties of installing and maintaining this type of software, ultimately it is helpful in terms of knowledge acquisition and as a beneficial investment librarians can make in themselves, their libraries, and their patrons.…

This article presents a case study in user-centered design that explores the needs and preferences of undergraduate users. An analysis of LibQual+ and other user surveys, interviews with public service staff, and a formal American with Disabilities Act accessibility review served as the basis for planning a redesign of the Brown University…

Questions how anthropomorphic human computer interface design should be. Observes: the impulse to anthropomorphize technology has been longstanding, employed with artifacts besides computers; evolution of technologies proceeds through an introductory phase wherein a culture becomes acclimatized to the new technology; and the perception of…

Recent research on annotation interfaces provides provocative evidence that anchored, annotation-based discussion environments may lead to better conversations about a text. However, annotation interfaces raise complicated tradeoffs regarding screen real estate and positioning. It is argued that solving this screen real estate problem requires…

Analyzes interfaces supporting spoken, pen-based, and multimodal input for their effectiveness in interacting with interactive map systems. Results identified performance difficulties with speech-only map interactions that declined substantially when people could interact multimodally. Analyses also indicated that map displays can be structured to…

Of 45 adults over 50 who had computer experience, 44% reported difficulty reading screens, 53% were frustrated by complex software, and 27% had difficulty with the mouse. The physical characteristics of aging should be considered in designing special software features such as dynamic text resizing and menu buttons instead of pull-down menus. (SK)

Ken Klingenstein has led national networking initiatives for the past 25 years. He served as director of computing and network services at the University of Colorado at Boulder from 1985-1999, and today, Klingenstein is director of middleware and security for Internet2. Truth is, this networking innovator has participated in the development of the…

This paper reflects a collaborative effort between the New Media Consortium (NMC) and the JISC Innovation Support Centres, CETIS and UKOLN. The research underpinning the report makes use of the NMC's Delphi-based process for bringing groups of experts to a consensus viewpoint, in this case around the impact of emerging technologies on teaching,…

The University of Maryland University College (UMUC) serves a dispersed patron base, and its library has developed, over time, a circulation system for distributing physical research materials to its patrons throughout the United States. This article discusses the development of this system and its associated interface/database management system…

Describes performer-centric interface design and explains a model-based approach for conducting performer-centric analysis and design. Highlights include design methodology, including cognitive task analysis; creating task scenarios; creating the presentation model; creating storyboards; proof of concept screens; object models and icons;…
