Discusses the use of hypertext as an instructional tool and compares hypertext instruction with traditional instructional formats. Instructional design guidelines for hypertext are presented that focus on learner control, multiuser management, user interface, knowledge organization, and content representation. Limitations of learner control as an…

The danger of computers is not that people will be controlled by them but that they may imitate them, mistaking data for wisdom. Unobstructed access to facts can produce unlimited good only if matched by the desire and ability to discover what they mean and where they would lead. (MSE)

Addresses the question of how to write computer programs using explicit knowledge and rules-based systems. Highlights include the knowledge representation tool; the knowledge base on programming; and results of experiments that tested the system. Appendices include the set of rules for the experimental knowledge base and details of two…

Discussion of the study of interactive information retrieval (IR) at the Text Retrieval Conferences (TREC) focuses on summaries of the Interactive Track at each conference. Describes evolution of the track, which has changed from comparing human-machine systems with fully automatic systems to comparing interactive systems that focus on the search…

Discusses educational technology in general and then considers the drawbacks and possibilities of educational computer technologies as a subset. Suggests that the proper use of the computers needs to be addressed more than the mere fact of having computers. (LRW)

Voice over Internet Protocol (VoIP) is becoming a reality in many organizations. The potential for mobility in voice over wi-fi networks will derive demand for the technology. Wireless VoIP is poised to rival VoIP as an alternative telephony tool. Internet has been used to transport data in the form of packet. In the past, Internet did not support…

In today's technology-laden society human-computer interaction (HCI) is an important knowledge area for computer scientists and software engineers. This paper surveys existing approaches to incorporate HCI into computer science (CS) and such related issues as the perceived gap between the interests of the HCI community and the needs of CS…

A computational framework is presented for the generation of elementary speech acts to establish conceptual alignment between a computer system and its user. This article clearly distinguishes between 2 phases of the alignment process: message interpretation and message generation. In the interpretation phase, presuppositions are extracted from…

The semantic web or Web 3.0 makes information more meaningful to people by making it more understandable to machines. In this article, the author examines the implications of Web 3.0 for education. The author considers three areas of impact: knowledge construction, personal learning network maintenance, and personal educational administration.…

Introduction: Activity theory, developed in the USSR as a Marxist alternative to Western psychology, has been applied widely in educational studies and increasingly in human-computer interaction research. Argument: The key elements of activity theory, Motivation, Goal, Activity, Tools, Object, Outcome, Rules, Community and Division of labour are…

Experiments focused on (a) how a subject directs his attention and explores the problem environment created by the task to be learned, and (b) how the subject's learning process can be facilitated by CAI systems. In all experiments, the subject interacted with an automaton responsible for controlling the experimental environment. The automaton was…

In many industrial tasks a complex, interactive process must be controlled by a human operator in real-time, with or without the aid of a computer. In order to allocate functions between man and machine at the design stage, a model of human behavior and performance in such tasks is required. Progress towards such a model is analyzed. (Author)

A program structure based on recently developed techniques for operating system simulation has the required flexibility for use as a speech synthesis algorithm research framework. This program makes synthesis possible with less rigid time and frequency-component structure than simpler schemes. It also meets real-time operation and memory-size…

Knowledge about computer hardware is growing in importance for the humanist because of the increasing impact of small personal computers. A basic knowledge of hardware need not be either difficult to acquire or too technical to be useful. The informed scholar can contribute greatly to the humanization of computer systems. (CMV)

Discussion of the online searching process identifies the formulation of a search strategy as the major problem area for users of online systems. Artificial intelligence is suggested as a solution to this problem, and several expert systems for information retrieval are described. An annotated list of 24 items for further reading is included. (23…
