Classroom activity traditionally takes one of three forms, variously oriented toward the levels of individual students, small groups, or the whole class. CSCL systems, however, may enable novel ways to facilitate instruction within or sequence activity across these different levels. Drawing on theoretical accounts of learning at and across…

Recently, various computer networking courses have included additional laboratory classes in order to enhance students' learning achievement. However, these classes need to establish a suitable laboratory where each student can connect network devices to configure and test functions within different network topologies. In this case, the Linux…

Computer system is useful for improving real time and interactive distance education activities. Especially in the case that a large number of students participate in one distance lecture together and every student uses their own computer to share teaching materials or control discussions over the virtual classrooms. The problem is that within…

Purpose: The purpose of this study is to explore a support system for beginners in drawing in a networked environment. Learners can receive advice and assessments from art experts without time and/or place constraints by using the proposed system. The authors investigate the possibilities of online supporting drawing learning. Two key factors are…

The limitations of home Internet connections make Personal Videoconferencing (PV) interaction vulnerable to network trouble. This dissertation explores how novice couples collaboratively manage PV network trouble so as to carry on their conversation. It is found that transmission/reception and their perturbations are material frames for…

One way to bring concepts to life in an introductory data networks course is for students to physically build a network that addresses a real business problem. However it can be challenging to find a suitable business problem, particularly if the network can exist only during the class period. This case presents a realistic business scenario and…

With the ability of modern system developers to develop intelligent programs that allows machines to learn, modify and evolve themselves, current trends of reactionary methods to detect and eradicate malicious software code from infected machines is proving to be too costly. Addressing malicious software after an attack is the current methodology…

Exchange is a collaborative learning application, originally developed for wirelessly interconnected Pocket PCs, that provides support for students and a teacher performing a face-to-face computer supported collaborative learning (CSCL) activity in a Single Input/Single Display (SISD) mode. We extend the application to support a single display…

As educational and research needs have changed, libraries have changed as well. They must meet ever-increasing demand for access to online media, subscriptions to archives, video, audio, and other content. The way a user/patron accesses this information has also changed. Gone are the days of a few hardwired desktops or computer carts. While…

There has been a rapid increase in the number of technology certificate programs offered around the world in the last decade. While designing, developing, and implementing these programs little or no consideration is given to geographical, cultural and developmental differences between different regions of the world. This study investigates the…

Twitter (www.twitter.com) has become kind of a popular culture punch line. It's often used as a shorthand to represent how self-obsessed and self-involved the American culture has become, and while Twitter does lend itself to a kind of needless sharing, it also has some potentially useful features. Twitter is a microblogging service that allows…

Regardless of whether an institution is a reluctant passenger on the racing technology train or itching to throw another shovel of coal on the fire, continuing advancements in technology make it a formidable factor in life on college campuses today. While students are updating their most recent social networking sites, faculty, staff, and…

University CIOs and their municipal counterparts will need to ensure that broadband systems provide plenty of bandwidth for hundreds of different devices used by thousands--and perhaps even millions--of users. Some university WiFi networks are already clogged with too many users. Moreover, universities must somehow provide wireless network access…

In this paper we present a CDN-based system, namely the COMODIN system, which is a media on-demand platform for synchronous cooperative work which supports an explicitly-formed cooperative group of distributed users with the following integrated functionalities: request of an archived multimedia session, sharing of its playback, and collaboration…

Oregon State University's demand for bandwidth to support scientific collaboration and research continues to grow exponentially, while state funding declines due to hard economic times. The challenge faced by these authors was to find creative yet fiscally responsible ways to meet OSU's bandwidth demands. Looking at their options for high-capacity…
