AHA! is a simple Web-based adaptive hypermedia system. Because of this simplicity it has been studied and experimented with in several research groups. This paper identifies shortcomings in AHA! and presents AHA! version 2.0 which tries to overcome the known problems with AHA! while maintaining its biggest asset: simplicity. The paper illustrates…

When students feel that their learning needs are not being met by computer-aided instruction, learning becomes passive, often resulting in boredom, frustration or a dislike for learning with computers. "Button Theory" allows the student to express his feelings and questions to the computer at the touch of a button, thus enhancing control over the…

Due to a rapidly increasing demand for bibliographic instruction, Southwestern College in San Ysidro, California, devised an interactive English-Spanish multimedia library skills program using Macintosh and Kodak PhotoCD technologies. First, a PhotoCD containing 100 photos of library services was produced. Then, an interactive Macintosh program…

This paper deals with the design of an integrated system for Web-based distance education (ISWBDE). At the highest level, this system can be dissected into two sub-systems: an integrated course authoring system (ICAS) and an integrated course delivery system (ICDS). The ICAS is designed to help with, or automate the creation and management of…

Computer assisted language learning (CALL) packages offer the majority of students who are learning English as a foreign language the opportunity for individual instruction. To meet the needs of an individual student, an adaptive CALL environment must have a dynamic model of student performance, a means of varying the difficulty of the learning…

This paper introduces and analyzes problems and issues in the design and use of cognitive tools in open, user-centered learning environments. It introduces a classification scheme for tool functions, and showcases several tools in a current educational hypermedia research and development effort. Information-seeking, information-presentation,…

The quality of multimedia-based interaction is more the product of the way instruction is designed, and less the result of the system on which it is delivered. To fully exploit the capabilities of more powerful instructional technologies, designers must also reexamine the assumptions and expand the strategies employed in instructional design.…

The World Wide Web has developed as the de facto standard for computer based learning. However, as a server-centered approach, it confines readers and learners to passive nonsequential reading. Authoring and Web-publishing systems aim at supporting the authors' design process. Consequently, learners' activities are confined to selecting and…

This paper describes a Web-based question-answering system called E-teacher that can be used in both traditional and distance learning courses to review academic contents. E-teacher is a self-editing template-based system that consists of a set of PHP scripts that generate the HTML code dynamically, or "on the fly." The entire E-teacher…

The goal of the Carnegie Mellon Online project is to build an infrastructure for delivery of courses via the World Wide Web. The project aims to deliver educational content and to assess student competency in support of courses across the Carnegie Mellon University (Pennsylvania) curriculum and beyond, thereby providing an asynchronous,…

Modeling the functions of a teacher in a computer interface is not a new practice; most computer applications employ electronic performance support systems (EPSS) such as online help, wizards, coaches, and even some forms of artificial intelligence. This paper presents easy-to-implement strategies for increasing learner autonomy by embedding…

A difficult task in creating rich, exploratory interactive learning environments is building an environment that is truly engaging. Engagement can be defined as the nexus of intrinsic knowledge and/or interest and external stimuli that promote the initial interest in, and continued use of a computer-based learning environment. Complete and total…

This paper describes the architecture and discusses implementation issues of a scalable Internet-based teaching and learning system (SKILL) being developed at the University of Essen (Germany). The primary objective of SKILL is to cope with the different knowledge levels and learning preferences of the students, providing them with a collaborative…

A graduate distance course on Information Systems Analysis and Design was designed and delivered under the guidance of the following four philosophies: (1) an effective education is a learner-centered education; (2) distance students are more likely to experience situated learning and problem-based learning; (3) enforced learning should enable…
