The "cyberinfrastucture" is a broad informational network that entails connections to real-time data sensors as well as tools that permit visualization and other forms of analysis, and that facilitates access to vast scientific databases. This multifaceted network, already a major boon to scientific discovery, now shows exceptional promise in…

Social and mobile technologies offer users unprecedented opportunities for communicating, interacting, sharing, meaning-making, content and context generation. And, these affordances are in constant flux driven by a powerful interplay between technological innovation and emerging cultural practices. Significantly, also, they are starting to…

The interoperability of educational systems, encouraged by the development of specifications, standards and tools related to the Semantic Web is limited to the exchange of information in domain and student models. High system interoperability requires that a common framework be defined that represents the functional essence of educational systems.…

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;…

Discusses how to increase user satisfaction by designing information retrieval systems that inform the user while the user is interacting online. Models the information processing operations of a user who has received an information message from the system and is stimulated into grasping at a higher understanding of the information need. (Contains…

Describes how to construct questions to test all cognitive levels of learning for a course in introductory programming. The framework for learning is based on Bloom's taxonomy. Practical advice is given through examples and by describing a computer system to help deliver quizzes. Includes example questions. (Author/AEF)

Examines ways in which intelligent tutoring systems can be used to develop models of a student's domain knowledge, problem solving abilities, and learning strategies. Cognitive skills assessment is discussed, and an example of a problem based tutoring system, Qualitative Understanding of Electrical System Troubleshooting (QUEST), is explained. (25…

Discusses knowledge, organization, and the organization and representation of knowledge. Addresses the relevance of international auxiliary languages as problems of development and use of special sign systems. Argues that--for computer realization of intellectual processes by modeling, not imitation--the psychological mechanisms of human memory…

This report begins by discussing the implications of a constructivist epistemology for instructional design and development, as well as drawbacks of the content database in instruction, the lack of special tools to help the learner actively construct knowledge, and emphasis on learning environments based on individual learning. The whole learning…

Discusses the concept and design of an enriched learning and information environment that was originally developed at Indiana University in partnership with AT&T (American Telephone and Telegraph). Topics addressed include constructivism, cognitive tools, representing expert behavior, apprenticeship, technological tools, information tools,…

As a person learns, his problem solving ability improves and one reason for this is the increased acquisition of "macro-rules" which make problem solving more efficient. An intelligent computer assisted learning (ICAI) system is being developed which automatically acquires the useful knowledge from the domain experts; as experts give the learning…

Describes PRECEPTOR, an intelligent tutoring system that provides multiple explanations for algebraic word problems involving two variables. Modeling the cognitive processes of an effective teacher is discussed, the capacity for individualized tutoring is examined, and differential tutoring based on varying difficulty levels is explained. (17…

Defines cognitive computer tools as software programs that use the control capabilities of computers to amplify, extend, or enhance human cognition; suggests seven ways in which computers can aid learning; and describes the "Learning Tool," a software package for the Apple Macintosh microcomputer that is designed to aid learning of…

The use of microcomputer-assisted therapy as part of the total rehabilitation plan for brain-injured individuals with cognitive-communicative impairments is addressed. Design of effective computer-assisted remediation requires a careful decision-making process. Specific types of software are suggested for dealing with deficits in organization,…

This paper makes basic assumptions regarding the development of an intranet architecture that will actively promote the cognitive apprenticeship of a new community of learners. The authors consider the intranet as a dynamic and virtual environment in which individuals may communicate, share resources, and reciprocally generate and organize…
