Introduces a multiagent architecture based on the blackboard system that enables different processes that perform multimodal presentation planning to communicate with each other. Describes a constraint propagation mechanism that transfers plan constraints from one level of the presentation planning process to the next. Discusses the cooperation…

Describes the use of a computer-linked camera to demonstrate Coulomb's law. Suggests a way of reducing the difficulties in presenting Coulomb's law by teaching the inverse square law of gravity and the inverse square law of electricity in the same unit. (AIM)

Discusses the application of computer based training (CBT) to human-computer interface design. Describes course considerations; courseware; and software environment for practice, and presents a case study outlining small group production of interactive guidebooks. Concludes that CBT can reduce instructional time and is an effective method for…

Discusses a laboratory course to familiarize mechanical engineering students in the use of electronics and computers. Describes the objectives, laboratory facilities, lecture topics, projects, and laboratory exercises for the course. (YP)

Describes an algorithm for computer generation of hierarchical indexes for document collections. The resulting index, when presented with a graphical interface, provides users with a view of a document collection that permits general browsing and informal search activities via an access method that requires no keyboard entry or prior knowledge of…

Discusses how the World-Wide Web (WWW) can be linked to the PAT system, a search engine supporting access to Standard Generalized Markup Language (SGML) encoded documents. Technical concepts are reviewed, and the operation of a PAT-to-Web gateway is explained using examples of how it is employed. (JKP)
