Abstract

In VIENA Classroom (short for VIEw NAtural Classroom, a powerful extension of the existing VIEW Classroom system) the teaching material is prepared as hypermedia documents and presented to the students. Students arer free to ask questions at any time which are either answered directly from the FAQ knowledge base or transferred to the teacher for later processing. By means of a multimodal natural language interface the students can formulate their questions directly in Japanase. As additional assistance the students can browse through context-semsitive ranked lists of FAQ

Abstract

Techniques to aid the manipulation of a computer based document were tested by a group of 38 novice users. The subjects were given a period of time to browse the document, and were subsequently given a set of goal related tasks in a questionnaire/answer session. The techniques tested were sequential paging, index referral, text fins and embedded hypertext links. 3 differing types of link mechansms were assessed and compared with each other. Sequential paging and index referral were the most commonly used of the techniques. Text find was employed more for goal related tasks than for browsing. The hypertext link technique was generally unpopular, especially for goal related tasks. In order to establish the importance of the text find technique, the effect on reading strategies without this facility was also investigated. For browsing operations, an increase in paging and decrease in hypertext linking was observed. In the case of goal directed searching, an increase was observed in paging and index referral techniques. The study calls into question the usefulness of hypertext in educational software

Abstract

A major difficulty of query writing for databases is that users do not fully understand queries. Proposes a system providing feedback to enable users to better understand their queries. It is a multi-functional rule-based system. In addition to providing an English translation for the query, it pin-points syntax errors, and suggests possible solutions. Finds likely semantic errors, and provides possible solutions. The system was implemented for a query language based on the entity relationship model. It is expected to lead to better user performance. Empirical testing showed significant improvement in user performance with the feedback system. The system can be used for computer-aided training and in actual operation

Abstract

TEPACIS is a computer assisted instruction package on CDS/ISIS which simulates the running of CDS/ISIS by allowing and accepting keyboard input of command codes and data. It is divided into 16 chapters, each presenting background information and guiding the learner to interact with CDS/ISIS in a simulated environment. TEPACIS includes enough background information on database formats, steps ind esigning a database, inverted index files, and so on, to make it useful to those interested in bibliographic databases in general. A second part, dealing with more advanced features of the software, is being developed

Abstract

The elements of desirable research design for the evaluation of educational technolgy are discussed with reference to the context of existing research. Sources of internal invalidity, type of compared educational acitivity, and outcome measures are considered. Finally, recommendations regarding the direction of evaluation research are made. Research designs that take into account the characteristics of the learner, the software, and the taecher preferably within the framework of a model of the learning process should be adopted

Abstract

Considers the role of computer-based simulations in an educational context. From dynamic spreadsheets through microworlds to virtual reality, the convenience and the intrinsic appeal of simulated environments exist in tension alongside concerns regarding the relationship of the simulated to the real and the consequences for human thought, learning and behaviour. Examines these issues in relation both to familiar educational computing environments and to others under development

Abstract

Hypertext provides a flexible environment in which to explore information. This makes it suitable for use with instructional software where students can exchange a linear progression for a more individualised exploration of the material. When designing instructional hypertext prgrammes, decisions must be taken on the degree of learner control rather than programme control. Learner control gives to the individual learner a control over the learning strategy; programme control imposes upon the learner, to some degree at least, that strategy. Discusses the arguments for and against learner control of hypertext environments in an instructional context and reviews the research evidence on learner control

Abstract

Presents an alternative paradigm to the traditional Knowlegde Based Expert System Paradigm for developing a full-scale Intelligent Tutoring System (ITS). This alternative paradigm integrates Minsky's Frames with hypertext and has been successfully deployed in the development of PEDRO, an ITS for foreign language learning, SONATA, an ITS for music theory learning and INTUITION, an ITS for gaming-simulation

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

Reports the results of a survey of end users of CD-ROM databases, at Ballarat University, Victoria, and the application of the Author authoring software to the development of a user training system (computer assisted instruction), called CDIntro, designed to address the issues raised by the survey. In the 6 months following the launch of CDIntro commercially, it has been purchased by 20 academic and hospital libraries and 2 library schools in Australia and New Zealand

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

Organizations are fielding increasingly complex systems for use ny knowledge workers at all levels. This often results in situations where the operators' skills, knowledge, and abilities are not sufficient to ensure efficient, accurate performance. Often, the solution has been the development of online help, Computer Based Training, or job aids. However, none of these alone provides the full support that the integration of AI technologies, hypermedia, and CBT could offer. Introduces the concept of Performance Support Systems, whose components include embedded training, hypermedia help, AI-based coaches, and an adaptable model-based user interface. Explores the concept through a discussion of the design of a PSS for a complex database system
