The purpose of this paper is to familiarize instructional designers and researchers with a useful design and research paradigm known as "Ask Systems." Ask Systems are interrogative interfaces to information and learning environments that model conversations with a skilled, reflective practitioner (Schon, The reflective practitioner, "1983") or…

Interactive learning environments (ILEs) are increasingly used to support and enhance instruction and learning experiences. ILEs maintain and display information, allowing learners to interact with this information. One important method of interacting with information is navigation. Often, learners are required to navigate through the information…

This work explores the feasibility of proposing universal design guidelines for E-training modules considering aging differences as an important factor. A controlled experiment was designed and conducted to evaluate the effects of module design characteristics on information recall, satisfaction, disorientation, and task workload, and the…

An innovative concept of an electronic learning system has been established in an attempt to achieve a technology that provides engineering students with an instructive and affordable framework for learning engineering-related courses. This system utilizes an existing Computational Fluid Dynamics (CFD) package, Active Server Pages programming,…

An adaptation technique of multimodal interfaces based on a cognitive modeling of users is presented in this paper. The adaptation process tries to select a combination of modalities that best fits the cognitive profile of each user. This profile contains indicators of cognitive abilities and styles. This paper focuses on output modalities and…

Reviews literature in the field of human-computer interaction (HCI) as it applies to educational environments. Topics include the origin of HCI; human factors; usability; computer interface design; goals, operations, methods, and selection (GOMS) models; command language versus direct manipulation; hypertext; visual perception; interface…

This paper describes the Perseus Project, an undertaking begun in the Classics Department of Harvard University devoted to the creation of a massive interactive hypermedia product on ancient Greek culture. The project is discussed in terms of its importance; contents; funding; development; delivery systems; future releases; costs; user acceptance…

Hypertext is well-suited for educational applications where open learning and knowledge exploration is desired. In such applications, principles of good hypertext interface design should be employed to avoid navigational problems so as to maximize learning. Interface design, however, may also directly enhance acquisition of a particular knowledge…

Investigates the effects of two hypermedia interface design strategies on learner efficiency, perceptions of usability, and performance. Compares undergraduate student outcomes of comprehending and locating information by using manual and visual filtering via computers. Findings support the use of these filtering tools as methods of increasing…

This paper describes technical and educational issues related to the development of SIMMPATICO, a multimedia tool for the teaching of Portuguese as a foreign language. The first section presents an overview of the motivation for the project. Package organization is discussed in the second section, including the linguistic approach and its…

Computer-based learning (CBL) is well established and its benefits are widely reported. It has found considerable utility in recent years with the explosion in interest in the use of the Web as a knowledge medium. Many online courses, however, consist merely of a series of textual notes and pictures with little navigational information or choice.…

An application specific style guide was produced for a large web-based multimedia and hyper-media learning project. It was introduced to 15 different sets of developers at Universities in disparate locations to promote consistency and good HCI practice for the whole project. This paper discusses the reactions to the use and practicality of the…

This paper reports on a project aimed at designing, implementing, and evaluating a hypermedia system, IPER-3, facing the three classical problems in the history of mathematics (i.e., trisection of the angle, quadrature of the circle, and duplication of the cube). The goal of the project is to study the opportunities offered by this kind of…

Sixteen courses were taught over a 2-year period at eight universities using Perseus, a HyperCard-based hypermedia information system that contains multimedia information about the Greek world, in order to examine how type of assignment influenced student perceptions about the Perseus interface and learning performance. Data collection methods…

This study examined the effects of the number of links and the granularity of nodes on undergraduate and graduate students' information searching, learning performance, and attitude toward hypermedia systems. Discusses the relationship between the number of links and cognitive overhead an/or disorientation as well as implications for Web-based…
