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…

Radford University was recently configured with a campus-wide wireless local area network. Using these new capabilities, a classroom-based Honors section of Concepts of Biology was conducted solely using electronic technologies (paper was never transferred from professor to student). To accomplish this, students used common software and freeware.…

Purpose: eduroam[TM] has already been proved to be a scalable, secure and feasible way for universities and research institutions to connect their wireless networks into a WLAN roaming community, but the advantages of eduroam[TM] have not yet been fully discovered in the wireless community networks aimed at regular consumers. This aim of this…

Much of our critical infrastructure is controlled by large software systems whose participants are distributed across the Internet. As our dependence on these critical systems continues to grow, it becomes increasingly important that they meet strict availability and performance requirements, even in the face of malicious attacks, including those…

In this dissertation, the author examined the capabilities of virtual private networks (VPNs) in supporting teleworking environments for small businesses in the food marketing sector. The goal of this research was to develop an implementation model for small businesses in the food marketing sector that use a VPN solution to support teleworker…

A parent walking into a classroom in a Minnesota public school today will be presented with a different learning environment compared to that of 20 years ago. Gone are filmstrips and movie projectors and in their place are computer screens. Today's classroom is a heavy user of digital media, and much of that is accessed via the Internet. It is…

People use external knowledge representations (KRs) to identify, depict, transform, store, share, and archive information. Learning how to work with KRs is central to be-coming proficient in virtually every discipline. As such, KRs play central roles in curriculum, instruction, and assessment. We describe five key roles of KRs in assessment: (1)…

This study documents to what extent writing on a blog in a networked learning environment could influence the affective variables of elementary-school students' writing. The framework is grounded more specifically in theory of self-determination (Deci & Ryan, 1985), relationship to writing (Chartrand & Prince, 2009) and the transactional…

The development of telerobotic systems has evolved from Single Operator Single Robot (SOSR) systems to Multiple Operator Multiple Robot (MOMR) systems. The relationship between human operators and robots follows the master-slave control architecture and the requests for controlling robot actuation are completely generated by human operators. …

The author has been a witness to the birth of the personal computer culture, with its intense one-on-one relationships with machines, and then to the development of the networked culture, with people using the computer to communicate with each other. In her most recent work on the revolutions in social networking and sociable robotics, she sees a…

In this era of political rancor when everything is a zero-sum game, it is refreshing to think that two parties could actually come together to create a win-win situation. That is exactly what is happening, though, as a number of universities take on the role of application service provider (ASP) for smaller schools. It is not all confetti and…

Preservation has long been considered a fundamental responsibility of research libraries. Data on preservation activities by its members has been collected by the Association of Research Libraries (ARL) since 1987, but changing digital technologies and the research, teaching, and learning environments in which research libraries are engaged…

Whether for an entire district, a single campus, or one classroom, allowing authorized access to a computer network can be fraught with challenges. The login process should be fairly seamless to approved users, giving them speedy access to approved Web sites, databases, and other sources of information. It also should be tough on unauthorized…

This report reflects a collaborative research effort to help inform Brazilian educational leaders about significant developments in technologies supporting teaching, learning, and creative inquiry in primary and secondary education. In an effort that ran from August through October 2012, a carefully selected group of 30 experts considered hundreds…

Historically, managing access to information systems (ISs) required direct interaction with a limited number of users. Increasingly, managing access involves handling an increased numbers of internal and external students, faculty, and staff as well as partners such as workforce development centers, the U.S. Department of Education, and the…
