This report discusses some of the problems and limitations in existing internetwork design for the connection of packet-switching networks of different technologies and presents an algorithm that has been shown to be suitable for internetworks of unbounded size. Using a new form of address and a flat routing mechanism called Cartesian routing,…

Describes one way of structuring an intelligent tutoring system (ITS) in light of developments in artificial intelligence. A specialized intelligent operating system (SIOS) is proposed for software for a network of microcomputers, and it is postulated that a general learning system must be used as a basic framework for the SIOS.

Discussion of the need for distributed information retrieval systems focuses on a model system, Fulcrum FUL/Text. Differences from distributed database management systems are described; system design is discussed; implementation requirements are explained including remote operation calls (ROC's); and a prototype simulation model based on FUL/Text…

A framework for assessing the implementation and impact of office automation (OA) technology within shore-based facilities of the U.S. Navy is provided. Following a list of the assumptions guiding the evaluation plan, a model for data collection is presented which is based on the perspective of a work group, i.e., a small number of individuals who…

Asynchronous computer-based conferencing offers several unique capabilities as a medium. Participants can read and write messages at whatever time is convenient for them, groups can interact even though participants are geographically separated, and messages are available to readers almost instantly. Because the medium has served for over a decade…

This study is an attempt to determine the extent of telecommunications use by secondary school science teachers in the Queens borough of New York City. Science teachers in 39 middle schools and 32 high schools were surveyed in May, 1994, in the following categories of information: access to computers, hardware preference, hardware in use, access…

One means by which subordinate leaders in armor units can practice command, control, and communication (C3 skills) before participating in field exercises is with the use of a computer supported battle simulation. This report describes the functional requirements and hardware configuration for Simulation in Combined Arms Training (SIMCAT), a…

The goal of the Educational Technology Center (ETC) Computer-based Conferencing Project has been to explore the potential of computer-mediated communication to support teachers in collegial exchange about their subject and practice, and to develop recommendations for future applications and management of such conferences. The purposes of this…

Three middle school teachers of mainstreamed students with mild disabilities used a computer networking system to check student understanding of math concepts. Results indicated that, with coaching on how to use the data generated by the system, teachers increased the amount of time spent on active teaching and providing feedback. (Author/JDD)

This research project was designed to evaluate the synergistic effects of linking workshops for science teachers with electronic conferencing. The rationale for this study was that these two methods of professional development and communication would have an impact beyond that which either would have alone. Included are the abstract, a description…

This descriptive study examines how the proliferation of electronic hook-ups to remote locations, to databases, and particularly to electronic mail (e-mail), is changing the work, communication patterns and self-image of higher education faculty. In particular the study examined whether technological acquisition had an impact on professors'…

The Educational Technology Center (ETC) was established by the National Institute of Education in October, 1983, in order to find ways of using the computer and other information technologies to teach science, mathematics, and computing more effectively. This report describes the ETC, presents its framework for research, and summarizes work on 12…

Teacher isolation is a significant problem in the science teaching profession. Traditional inservice solutions are often plagued by logistical difficulties or occur too infrequently to build ongoing teacher networks. Educational Technology Center (ETC) researchers reasoned that computer-based conferencing might promote collegial exchange among…
