Troubleshooting is a particular problem-solving process comprising error detection, fault diagnosis, and system restoration. Since automation of systems has become increasingly complex and ubiquitous, troubleshooting skills are crucial to maintain safety and security in a variety of contexts. The planned study aims at examining troubleshooting…

For electronic resources and reference librarians, fielding eresource access problems is often a daily task. A library user clicks on a link to an electronic journal article, book, or primary source and is unable to access the full text. Sometimes this problem occurs due to a lapsed subscription, a broken link, or a proxy configuration error. The…

Virtualization technology has been around for many years, and its use is increasingly becoming common in education, in general and in computing fields, in particular. This can be attributed partly to its potential to reduce costs, boost efficiency and overcome limited resources through its virtual applications such as servers, storage devices and…

In this paper we describe the development and refinement of "evidence rules" and "measurement models" within the "evidence model" of the "evidence-centered design" (ECD) framework in the context of the "Packet Tracer" digital learning environment of the "Cisco Networking Academy." Using…

When it comes to dealing with cyber attacks, there's no silver bullet. Ironically, however, college educators are already accustomed to wielding what may be the best weapon of all--education. Assaulted by the myriad species of spam, worms, Trojan horses, spyware, viruses, and other diseases that so easily infect and sometimes devastate campus…

This study examined the effects of manipulating the modality (text-only, voice-only, voice+text) of a tutorial and restriction (restricted vs. unrestricted) of a simulation's interface on retention and transfer of tutorial content. The tutorial prepared novice students to use Packet Tracer, a simulation developed by Cisco that teaches network…

This article represents the second part of a series in this journal called "How to Perform a Security Audit." It continues the conversation on setting up a process for identifying security-related concerns and implementation safeguards. It continues the conversation from the perspective of system monitoring. This article discusses how to use a…

Whereas great advances have been made in the statistical sophistication of assessments in terms of evidence accumulation and task selection, relatively little statistical work has explored the possibility of applying statistical techniques to data for the purposes of determining appropriate domain understanding and to generate task-level scoring…

Describes one decision-making approach for quickly implementing a communications network into a school district. The use of volunteer labor for wiring installation, computer selection focusing on standardization to aid in troubleshooting, and an intranet system to achieve efficiency and learning opportunities for teachers and administrative…

In computer-based simulations, students must bring a wide range of relevant knowledge, skills, and abilities to bear jointly as they solve meaningful problems in a learning domain. To function effectively as an assessment, a simulation system must additionally be able to evoke and interpret observable evidence about targeted knowledge in a manner…

Presents issues about school networking: how network administrators differ from technology directors; what administrators, technology directors, teachers, and students need to know; whether school library media specialists should serve as network administrators; why basic networking knowledge is advantageous; causes of problems affecting networks;…
