Mobile learning has become increasingly popular in the past decade due to the unprecedented technological affordances achieved through the advancement of mobile computing, which makes ubiquitous and situated learning possible. At the same time, there have been research and implementation projects whose efforts centered on developing mobile…

Discussion of natural language processing components of information retrieval systems focuses on a full-text system called TOPIC (Text-Oriented Procedures for Information Management and Condensation of Expository Texts) that is based on text parsing. Highlights include design rationales for semantic parsing; text coherence; and a semantic model of…

Discusses and examines two approaches to concept-based retrieval of hypermedia information that improve a user's ability to navigate large systems--term indexing with semantically coupled thesauri and semantic hyperindexing. Visualization of index structures is discussed, and an example, the Cube of Contents retrieval model for the "Active…

Reviews published findings from empirical studies of hypermedia learning and cognitive styles and classifies them into five themes: nonlinear learning, learner control, navigation in hyperspace, matching and mismatching, and learning effectiveness. Presents a learning model and discusses implications for the design of hypermedia learning systems.…

Discusses the design of computer applications, focusing on understanding design representations--what makes design representations work, and how, in different contexts. Examines the place of various types of representation (e.g., formal notations, models, prototypes, scenarios, and mock-ups) in design and the role of formalisms and representations…

Discussion of intelligent computer-assisted instruction (ICAI) systems focuses on tutorial strategies. Highlights include artificial intelligence; degree of learner control; student modeling requirements in ICAI; ICAI system architecture; forms of knowledge; and tutoring functions, including questioning, teaching, and motivating. (17 references)…

Explores the use of visualization to enhance the information retrieval process, particularly in bibliographic retrieval systems. Topics discussed include document retrieval systems; human visualization; the VIBE (VIsualization by Example) system, a prototype system for visualizing a collection of documents; and differences between VIBE and more…

Presents evidence to show that the body plays a continuing and fundamental part in the process of thinking and the development of the knowledge used to think. Topics discussed include knowledge structures and representations; artificial intelligence; feeling; learning processes; models of knowledge; information retrieval; and implications for…

Examines the functional characteristics of intelligent computer-assisted instruction (ICAI), proposes a structural model that defines expertise requirements for the development of an ICAI system, and discusses the requirements of a multidisciplinary cooperative effort for its development. Knowledge acquisition, learning needs, and instructional…

This report incorporates a literature review, a workshop paper, and discussion by workshop participants on the current status of research on what the users of computer systems know, and how these different forms of knowledge fit together in learning and performance. It is noted that such research is important to the problem of designing systems…

These two articles discuss the contributions of behavioral and cognitive psychology to the design of computer-based instruction (CBI) and describe an integrated meta-model for use with instructional systems design (ISD) called ROPES + (Retrieving, Orienting, Presenting, Encoding, and Sequencing). Highlights include motivation, information…

Discusses approaches to the integration of query-based information retrieval and browsing in a hypertext network. A prototype system developed to evaluate the proposed approach in terms of retrieval effectiveness and search efficiency is presented, and design and implementation issues concerning the prototype are considered. (30 references) (EA)

This paper summarizes some of the current approaches to student modelling in Intelligent Tutoring Systems (ITS) and proposes ways in which learning algorithms can be applied in ITS. The role of machine learning in tutoring systems is described, including student modelling, teaching strategies, and collaborative learning. The PIXIE system and the…

This survey of intelligent tutoring systems describes the components of these systems, different teaching scenarios, and the relation of these systems to a theory of instruction. It argues that the underlying pedagogical approach is to make latent knowledge manifest by using different forms of quantitative modeling: (1) simulating physical…

Reviews the evolution of instructional systems design and computer-based learning environments, focusing on the effects of technological advances. Classification of learning environments is discussed in the context of the dimensions of scope (macrolevel or microlevel), user activity (generative or mathemagenic), educational activity (goal-directed…
