Online knowledge assessments have a range of well-known advantages over traditional pen-and-paper assessments, and have found their application in many domains of formal education. However, online assessments are still typically used in combination with extensive supervision in order to ensure assessment integrity and avoid cheating. Alleviating the need for assessment supervision, on the other hand,...
Audience response systems represent an important class of tools for improving lecture interactivity. Although they can provide a lecturer with valuable and timely data about his audience's opinions and understanding of the lecture, one of their main disadvantages reported in the literature is the additional time required for their usage within a time-constrained lecture. In this paper, the time aspects...
In this paper results of a study investigating the effects of formative self-assessments on students' learning achievements are presented. Formative online self-assessments were made available to students enrolled in a digital signal processing university course. Students' access logs and results were used to support or reject hypotheses regarding students' perception of formative self-assessments,...
Penetration testing is one of the key actions in ensuring information system security and thereby avoiding security incidents including eavesdropping or unauthorized access to internal systems. In traditional educational settings it can be difficult to provide training for practitioners to develop and practice wireless penetration testing techniques, due to the requirement for physical equipment which...
Concept maps are a learning tool that has been successfully applied in the educational process for more than three decades now. Their original aim was to serve as a learning aid, offering a more efficient overview of the learning content and more successful integration of new knowledge to the learner's schemata. Later, thanks to the popularization and increase in availability and applications of computers...
This paper describes a proposed automatized case-based cognitive skills assessment system. Unlike most currently available computer-based assessment systems that offer support only for simple assessment tasks, this system supports domain independent case-based assessment of cognitive skills or performance. Automatic feedback and performance evaluation functions of the system are based on extracting...
Classroom interactivity is today considered to be one of the most important preconditions for successful lecturing. It is also often considered to be the main drawback of learning from lecture captures. In this article, the issue of live lecture and lecture capture interactivity is addressed from the aspect of students' question posing. During several lectures, students were asked to write down all...
Classroom response systems (CRSs) present a class of tools which can enhance interactivity not just during the process of classroom teaching, but during lecturing in general. CRSs can provide the lecturer with valuable information about how the audience is following his lecture, based on which he can adapt the course of the lecture or correct misunderstood concepts as they are detected. AuResS, a...
Availability, the degree to which a system is in a specified, operable state, is a critical criterion in overall information systems' quality. Since network services are the core infrastructure components for any modern business, their uninterrupted functioning becomes the critical issue in sustaining the business itself. Deployment of a production ready system to ensure high availability is not an...
