This dissertation explores the use of geometric and graphical models for a variety of information search and filtering applications. These models serve to provide an intuitive understanding of the problem domains and as well as computational efficiencies to our solution approaches. We begin by considering a search and rescue scenario where both…

This study examined the effects of the "READ 180"[R] program on the reading achievement levels of fourth grade students who participated in the "READ 180"[R] program (Scholastic Incorporated, 2005) compared to fourth grade students who were reading below grade level but who were not participating in the "READ 180"[R]…

Web 2.0 technology is expanding rapidly from social and gaming uses into the educational applications. Specifically, the multi-user virtual environment (MUVE), such as SecondLife, allows educators to fill the gap of first-hand experience by creating simulated realistic evolving problems/games. In a pilot study, a team of educators at the…

This study presents a cost effective, reliable, and convenient mobile web-based system to facilitate the dissemination of course information to students, to support interaction that goes beyond the classroom. The system employed the Really Simple Syndication (RSS) technology and was developed using Rapid Application Development (RAD) methodology.…

Web3D presents many opportunities for learners in a virtual world or virtual environment over the web. This is a great opportunity for open-distance education institutions to benefit from web3d technologies to create courses with interactive 3d materials. There are many open source and commercial products offering 3d technologies over the web…

Purpose: The purpose of the paper is to examine the various features and components of web-based online public access catalogues (OPACs) of IIT libraries in India with the help of a specially designed evaluation checklist. Design/methodology/approach: The various features of the web-based OPACs in six IIT libraries (IIT Delhi, IIT Bombay, IIT…

The purpose of this study was to determine the effectiveness of a hybrid learning approach to deliver a computer science course concerning the Microsoft office PowerPoint 2003 program in comparison to delivering the same course content in the form of traditional lectures. A hundred and seventy-two first year university students were randomly…

The purpose of the study is to examine the effect of appropriately designed multimedia software for both conversational and formal styles with respect to various variables. The model of nonequivalent control group was used in the study. While the group studying with the multimedia material in formal style included 22 students, the other group…

Most software tools that have been developed with the aim of helping students to learn school algebra have not yet achieved successful results in classroom. Almost all of them are menu-based systems that provide transformation rules in menus and buttons. Aplusix is a new interactive software tool for learning school algebra. In contrast to…

The purpose of this study was to develop a framework for analyzing and evaluating student-constructed models of physical phenomena and monitoring the progress of these models. Moreover, we aimed to examine whether this framework could capture differences between models created using different computer-based modeling tools; namely, computer-based…

The present article investigates the effects of individual and contextual variables on children's early learning in French nursery schools and German kindergartens. Our study of 552 children at preschools in France (299 children from French nursery schools) and Germany (253 children from German kindergartens) measured skills that facilitate the…

This study describes how in-service teachers in the pre-vocational sector in Mauritius adopted specific strategies to overcome the language barrier in the learning of science (Van Driel, Verloop & de Vos, 1998). Students of form III were taught few basic ideas related to "Earth & Space" through the use of role play and ICT. The…

Curriculum for global citizenship education is gaining momentum as countries have experienced an increase in interdependence and interconnectedness through technology over the last century. Through qualitative research, this study employed a phenomenological methodology to understand how ten female elementary teachers in grades third- through…

In the last decade one of the largest IT investments has unarguably been Enterprise Systems (ES). Evidence suggests that this trend will likely continue. In 2006 for example, the ES market had a revenue growth of over 14%--more than $28 billion. Despite the continued interest from organizations with regards to ES, many are still reluctant to adopt…

This paper presents a computer based diagnostic tool developed to facilitate the learning process. The developed tool is capable of generating possible error syndromes associated with the answers received. The developed tool simulates the error pattern of the test results and then accordingly models the action plan to help in children's learning…
