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…

In this article, an extension of the existing structure of learning objects is described. The solution addresses the problem of the access and discovery of educational resources in the distributed Internet environment. An overview of e-learning standards, reference models, and problems with educational resources delivery is presented. The paper…

This article deals with providing support for the execution of pedagogical scenarios in Learning Management Systems. It takes an engineering point of view to identifies actors, design and use processes. Next it defines the necessary capabilities of a platform so that actors can manage or use pedagogical scenarios. The second part of the article is…

In developing countries like India, the onus of development lies mainly with the government, which faces the predicament of multiple demands and limited resources. This leads to a situation where even fundamental objectives such as basic literacy for all are not met. On the other hand, there exists a vibrant private sector, which has resources and…

Starting from the first public draft of IMS Learning Design in November 2002, a research project at the Catholic University Eichstaett-Ingolstadt in Germany was dedicated to the conceptual examination and empirical review of IMS Learning Design Level A. A prototypical runtime environment called "lab005" was developed. It was built based…

This paper describes how computers were employed by workshop participants, the commercial materials used, some of the experiments performed using computer interfaces, and the effect of computer interfacing on the science laboratory. Increased student interest through the study of open-ended experiments is discussed. (CW)

Reviewed are six computer software packages including "Lunar Greenhouse,""Dyno-Quest,""How Weather Works,""Animal Trackers,""Personal Science Laboratory," and "The Skeletal and Muscular Systems." Availability, functional, and hardware requirements are discussed. (CW)

Introduces three different techniques to facilitate the measurement of speed and the associated kinematics and dynamics using a computer. Discusses sensing techniques using optical or ultrasonic sensors, interfacing with a computer, software routines for the interfaces, and other applications. Provides circuit diagrams, pictures, and a program to…

Describes a junior high school course in musical composition using Musical Instrument Digital Interface (MIDI) technology. Discusses course objectives and three composition projects. Includes a list of definitions and asserts that MIDI technology offers students and teachers a powerful method to study how music works. (CFR)

Examines the current state of user interface design for information seeking. Topics include technology push and interdisciplinarity; research and development; literature trends; user-centered interface design; information seeking in electronic environments; online information retrieval system interfaces; online public access catalog interfaces;…

A survey of recent publications shows that frequent topics of Internet and information retrieval research are the effectiveness of search engines, information validation and quality, user studies, design of user interfaces, data structures and metadata, classification and vocabulary based aids, and indexing and search agents. The changing balance…

Researchers have suggested that up to 50 % of the effort in development of information systems is devoted to user interface development (Douglas, Tremaine, Leventhal, Wills, & Manaris, 2002; Myers & Rosson, 1992). Yet little study has been performed on the inclusion of important interface and human-computer interaction topics into a current…

Computers, computer programs, and other novel and vivid technological applications to language learning can unintentionally redirect attentional resources and therefore increase the salience of unplanned as well as targeted features. Incidental activities such as keyboarding (Henry, 1992), manipulation of a mouse (Meunier, 1996), and other…

Topic Maps, ISO/IEC 13250 standard, are designed to facilitate the organization and navigation of large collections of information objects by creating meta-level perspectives of their underlying concepts and relationships. The underlying structure of concepts and relations is expressed by domain ontologies. The Topics Maps technology can become…

In an experiment designed to dissociate the effects of instructional approach and system interface on learning in computer-based instruction, 18- to 30-year-old high school graduates with low mathematics ability were tested before and after completing three mathematics practice modules. Found that low ability students may not learn from computers…
