Students' perception of live lectures' inherent disadvantages

This paper aims to provide insight into various properties of live lectures from the perspective of sophomore engineering students. In an anonymous online survey conducted at the Faculty of Electrical Engineering and Computing, University of Zagreb, we investigated students’ opinions regarding lecture attendance, inherent disadvantages of live lecture as a teaching method, lecture interactivity, and the importance of different types of learning materials. The findings derived from students’ reported data suggest that students are well aware of a number of limitations of live lectures as a teaching method, yet despite that awareness, it rarely affects their decision to attend live lectures or not. Implications of the findings for live lectures are addressed in the paper, as well as recommendations for future research.

Decision trees in formative procedural knowledge assessment

In this paper, an approach to automated formative assessment of procedural knowledge is described and evaluated. While assessment and representation of conceptual knowledge using visual aids such as of concept maps has often been analyzed and discussed in the literature, significantly less attention has been given to assessment of procedural knowledge. The approach described in this paper is based on automated evaluation of knowledge described by examinees in form of a decision tree against a repository of test cases. The examinee is afterwards provided with automatically generated feedback about the overall results of applying his decision tree, as well as possible changes required to correct them. The results of the pilot evaluation of a prototype system implementation are described and discussed.

Virtual wireless penetration testing laboratory model

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 can be used only by one person at the time, the need for student to be present at the location of the lab and the need to have expert in the lab to assess students progress. A virtual wireless penetration testing laboratory designed for educational purposes could overcome these problems. In this paper we propose a model of such a laboratory.

LeCTo: A rich lecture capture solution

Lecture capture is a term referring both to learning materials based on recordings of live lectures as well as software and hardware support systems enabling lecture recording and reproduction. As lecture captures are today becoming more and more valued learning materials, there is a strong need for quality yet simple to use lecture capture systems supporting their creation. In this paper we describe a software solution for rich lecture capture recording and reproduction. LeCTo, an application developed to maximize lecture capture learning potentials and simplify lecture capturing process is presented through its functionality as well as problems and solutions encountered during its implementation.
