This paper reports on an integration of concept mapping for manipulating and structuring knowledge with multimedia presentation technology. It presents the current development of the HyperMedia Activated Network authoring environment. HAN is an intelligent hypertext demonstrator system. The first HAN module, called ICADT, was developed initially to teach Computer Aided Architectural Design (CAA...

A method for providing uniform transparent access to disparate distributed information systems was demonstrated. A prototype testing interface was developed to access documentation and information using publicly available hypermedia tools. The prototype gives testers a uniform, platform-independent user interface to on-line documentation, user manuals, and mission-specific test and operations d...

The Hypermedia/Time-based Structuring Language (HyTime) is a recently adopted International Standard (ISO/IEC 10744:1992). The paper presents the need and potential for HyTime, provides a brief explanation of its various facilities and shows how it may be applied to good effect in various situations, with particular reference to hypertext interchange from Microcosm (an open hypertext system). I...

Second Language System of Motivational Selves and English Language Skills: The Role of Socio-Economic Status among Iranian Language Learners1 A. Parastaar Aski* M.H. Abdollaahi, Ph.D.** A. R. Moraadi, Ph.D.*** H. R. Hassanaabaadi, Ph.D.****   Learning English in Iran is quite popular, yet not all are successful at this task. To shed light on this dilemma and its root causes, the ro...

The use of subtitles in a Computer Assisted Language Learning (CALL) program can assist learners in the comprehension of the language input they are exposed to. In an interactive CALL program, subtitles may also help learners in the formulation of their own responses. This paper describes the evaluation of a speech interactive CALL program that combines speech recognition technology, embodied a...

This paper discusses theory and research issues associated with the use of hypermedia technologies to support learning. It is proposed that viewing hypermedia technologies as an enabling infrastructure for tools to support learning—in particular learning in problem-oriented pedagogical environments involving cases—has particular promise. After considering research issues with problem-oriented l...

The nature of computer based learning and instructional environments that support it have changed dramatically in the last decade. The growth of hypertext, hypermedia and multimedia provided the capabilities necessary for developing complex learning environments. The system described in this paper is being developed to be used in Personal Computer workstations with multimedia and network capabi...

This study examined the influence of cognitive style, spatial orientation and computer expertise on hypertext navigation patterns and learning outcomes when participants interacted with a hypermedia presentation. A sample of 306 undergraduates was pre-tested both on their cognitive style and on their selfreported frequency and ability in using computers. From the initial sample, 40 students wer...
