Abstract

Presents a pragmatic cognitive theory of instruction, the CLAI model (Cognitive Learning from Automated Instruction), which is intended to be a theory practically useful for developing real instructional systems. Defines learning from a cognitive perspective as well as a generation view of learning from instruction, and in particular from automatic instruction. Sets out different instructional theories relating cognitive processes and instructional events, and the CLAI model of instruction for intelligent tutoring systems (ITS). Illustrates a practical approach for ITS development and gives an example of integration of the model inside an automated tutor architecture

Abstract

Currently, adaptive educational hypermedia systems (AEHSs) are described using nonuniform methods, depending on the specific view of the system, the application, or other parameters. There is no common language for expressing the functionality of AEHSs, hence these systems are difficult to compare and analyze. In this paper we investigate how a logical description can be employed to characterize adaptive educational hypermedia. We propose a definition of AEHSs based on first-order logic, characterize some AEHSs resulting from this formalism, and discuss the applicability of this approach.

Abstract

Stresses the differences between library user training programmes designed for paper besed systems and those for online databases, such as online catalogues. Clarifies 2 aspects of databases, the structure and the access method, and discusses the pitfalls of making analogies to print materials. Searches involving print materials are dominated by linear or sequential patterns, while online searches are dominated by spatial or juxtapositional patterns

Abstract

The current generation of authoring systems provides tools for non programmers to create software. Provides guidelines for educators who wish to design custom software to meet either their own or other's needs. Many instructional design theories and related computer based empirical research findings are merged into a prescription for the most important facet of courseware development - instructional design. The instructional design process, based on Gagne's 9 events of learning, is broken into 4 domains: instructional set, teaching strategies, student performance, and issues unique to computer based instruction

Abstract

Reviews 2 multimedia CD-ROM database authoring systems: Macromedia's Authorware and AimTech's Icon Author; noting both their similarities and their major differences. Concludes that, if the Mac is of primary importance, then Authorware is the favoured choice, but if links to OS/2 or UNIX matter, then Icon Author is the mist likely choice

Abstract

Discusses the development of systems designed to improve methods of teaching and learning in schools, colleges and universities, an area currently receiving substantial funding in many countries. Outlines the history of early 'teaching machines' to the 1986 Domesday project and the multimedia hardware and softwware today, focusing on current UK, US and European software developemnt support projects. Reviews the literature on multimedia learning, identifying 2 key difficulties to be overcome; in the area of assessment methods, and the need for a better understanding of the nature of learning and system requirements

Abstract

Describes the efforts of Knight-Ridder Information (KRI) and Dun & Bradstreet (D&B) to provide Web based training systems. The KRI tutorial covers the DIALOG Web service, describes the technology, the tutorial and evaluates its usefulness. D&B's web based training trains users on its online system. It is more advanced than the KRI tutorial. Describes its training modules, and its testing of methods and technologies. The University of Texas as Austin has developed 2 tutorials on searching for patents and trademarks

Abstract

Increased learner control is one of the benefits of implementing hypermedia in instructional settings. However, prior research has not determined whether students using hypermedia systems that provide a large amount of learner control actually perceive themselves to be in more control over the learning environment than do student using traditional text-style materials. This is a significant issue because provision of increased control does nothing to help the student unless the student perceives the increased control. Students using hypertext to learn technical information experienced an increased sense of control. Further, it provides preliminary evidence of an increased level of intrinsic motivation to learn among hypertext users. Implications for further research regarding the effects of hypermedia on users' intrinsic motivation are discussed

Abstract

Here is an interactive introduction to neural nets and how to apply them that is easy to understand and use. Neural nets are information processing systems that mimic the basic structure of the human brain. They learn by adjusting the interaction of their individual components (neurons). A neural net can learn from patterns of information supplied as input to generate useful output that can serve as a basis for decision making. Numerous multimedia and interactive components give the learning program an almost game-like feel as it takes the learner from the basics to the use of neural nets for real projects

Abstract

To arrive at relevant and reliable conclusions concerning the usability of a hypermedia educational e-book, developers have to apply a well-defined evaluation procedure as well as a set of clear, concrete and measurable quality criteria. Evaluating an educational tool involves not only testing the user interface but also the didactic method, the instructional materials and the interaction mechanisms to prove whether or not they help users reach their goals for learning. This article presents a number of evaluation criteria for hypermedia educational e-books and describes how they are embedded into an evaluation procedure. This work is chiefly aimed at helping education developers evaluate their systems, as well as to provide them with guidance for addressing educational requirements during the design process. In recent years, more and more educational e-books are being created, whether by academics trying to keep pace with the advanced requirements of the virtual university or by publishers seeking to meet the increasing demand for educational resources that can be accessed anywhere and anytime, and that include multimedia information, hypertext links and powerful search and annotating mechanisms. To develop a useful educational e-book many things have to be considered, such as the reading patterns of users, accessibility for different types of users and computer platforms, copyright and legal issues, development of new business models and so on. Addressing usability is very important since e-books are interactive systems and, consequently, have to be designed with the needs of their users in mind. Evaluating usability involves analyzing whether systems are effective, efficient and secure for use; easy to learn and remember; and have a good utility. Any interactive system, as e-books are, has to be assessed to determine if it is really usable as well as useful. Such an evaluation is not only concerned with assessing the user interface but is also aimed at analyzing whether the system can be used in an efficient way to meet the needs of its users - who in the case of educational e-books are learners and teachers. Evaluation provides the opportunity to gather valuable information about design decisions. However, to be successful the evaluation has to be carefully planned and prepared so developers collect appropriate and reliable data from which to draw relevant conclusions.
