We present COLLECT-UML, a constraint-based intelligent tutoring system (ITS) that teaches object-oriented analysis and design using Unified Modelling Language (UML). UML is easily the most popular object-oriented modelling technology in current practice. While teaching how to design UML class diagrams, COLLECT-UML also provides feedback on…

In order to stay competent and update in the fast changing landscape of technological advances, professionals nowadays are expected to continuously upgrade themselves of professional knowledge and expertise in their respective fields. Many professional organizations stipulate that their members should take part in a minimum number of hours or…

This article discusses design and usability issues pertaining to context-sensitive "help" in computer-assisted language learning (CALL). As part of the discussion, we present a study in which we examined the effects of three independent factors on student usage of context-sensitive "help": feedback, exercise type, and language proficiency. Forty…

The use of numerical simulations to design and analyze new products requires both conceptual and operational knowledge. This paper describes COMPANION: an intelligent multimedia system for vocational training used by engineers and technicians. A key concept in terms of training methodology is that of "situated learning," or continuous…

Olae is a computer system for assessing student knowledge of physics, and Newtonian mechanics in particular, using performance data collected while students solve complex problems. Although originally designed as a stand-alone system, it has also been used as part of the Andes intelligent tutoring system. Like many other performance assessment…

Current workflow systems largely assume a closed network where all the software is available on a homogenous platform and all participants are locally linked together at the same time. The field of Electronic Distance Education (EDE) on the other hand, requires the next-generation workflow that will integrate workflows from a distributed…

The Human Use Regulatory Affairs Advisor (HURAA) is a Web-based facility that provides help and training on the ethical use of human subjects in research, based on documents and regulations in United States Federal agencies. HURAA has a number of standard features of conventional Web facilities and computer-based training, such as hypertext,…

Previous research into the behavior of students while learning to program by automatically recording their actions has revealed that such recordings contain a wealth of information that can be collected together into a diagnostic tool that can support students' learning. The first step has been to construct the Coach, a software component that can…

Examines the qualities of hypermedia information systems that enable them to facilitate learning and knowledge construction. Discusses the background of current learning theories, and describes a possible hypermedia system based on constructivist learning principles that could be developed through the use of intelligent autonomous agents.…

Describes the design of an intelligent Web-based interactive language learning system to support learning English as a second language on the Internet. Highlights include an interactive English writing environment; an authentic conversation learning environment; authoring tools to facilitate teachers' content preparation; system architecture; and…

Defines metacognition, examines metacognitive differences in learners, reviews past and current developments in intelligent tutoring systems, and introduces a computer-based system to help learners develop metacognition in studying from texts. Presents results of a study that analyzed the learning methods of students and makes suggestions for…

Discusses the application of the theory of contingent tutoring to the design of a computer-based system for algebra. Considers help seeking and analyzes interactions between secondary school students and the computer-based tutoring system to explore the relations between individual differences in learner-tutor interaction, learner's prior…

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…

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 need to improve the design of intelligent tutoring systems for young children and teenagers so they will develop information-processing skills and enrich their cognitive-emotional sphere. Gives an example of an experimental group in Moscow studying English as a second language. (LRW)
