Using Auditory Display to Teach Network Intrusion Detection
Teaching network intrusion detection, or NID (the identification of violations of a security policy in a computer network) is a challenging task, because students need to analyze many data from network logs and in real time to identify patterns of network attacks, making these activities visually tiring. This paper describes an ongoing research concerned with designing and applying sounds that represent meaningful information in interfaces (sonification) to support teaching of NID. An usability

Important Ornaments: The Impact of Graphics and Rule Systems on Academic Wiki Use
Collaborative websites, or wikis, are being used in the classroom to recruit user attention and to disseminate information [1). These wikis place a heavy emphasis on text, while generally neglecting graphics. Little to no research has examined the impact of this textual approach. This paper examines the use of graphics and rule systems as motivating tools in academic wikis. It reports the results of a 6 month long experiment involving 21 10th and 11th grade users to determine the impact of diffe

Efficient object based streaming framework for web-based education
An efficient moving object extraction algorithm suitable for real-time content-based multimedia streaming systems is proposed in this paper. A Motion Vector (MV) based object extraction is used to dynamically detect the objects. To utilize the bandwidth efficiently, the important object can be real time detected, encoded, and transmitted with higher quality and higher frame rate than those of background. In order to meet the real-time requirement, no computationally intensive operation is includ

Measuring knowledge convergence: Achievement similarity and shared knowledge in computer-supported c
Learning in small groups may result in convergent knowledge outcomes or foster possible prior differences between learners. Few studies, however, measure convergence or divergence of knowledge as an outcome of small group learning. This contribution analyzes knowledge convergence/divergence as an outcome of learning in small groups with the concepts of achievement similarity and shared knowledge rooted in two different theoretical frameworks. Achievement similarity means that learners acquired s

Automated Analysis of Students’ Free-text Answers for Computer-Assisted Assessment
We present an approach to Computer-Assisted Assessment of free-text material based on symbolic analysis of student input. The theory that underlies this approach arises from previous work on DidaLect, a tutorial system for reading comprehension in French as a Second Language. The theory enables processing of a free-text segment for assessment to operate without precoded reference material. A study based on a small collection of student answers to several types of questions has justified our appr

Can learning from molar and modular worked examples be enhanced by providing instructional explanati
In two experiments we explored how learning from traditional molar worked-out examples—focusing on problem categories and their associated overall solution procedures—as well as from more efficient modular worked-out examples—where intrinsic cognitive load is reduced by breaking down complex solutions into smaller meaningful solution elements—can be further enhanced. Instructional explanations or self-explanation prompts were administered to increase germane cognitive load. However, both int

Elaborating new arguments through a CSCL scenario
The CSCL community faces two main challenges with respect to learning and argumentation. The scientific challenge is to understand how argumentation produces learning, that is to discover which cognitive mechanisms, triggered by argumentative interactions, generate new knowledge and in which conditions. The engineering challenge is to determine how to trigger productive argumentation among students. These two challenges are often investigated in parallel, but this contribution focuses on the lat

Sequence effects in solving knowledge-rich problems: The ambiguous role of surface similarities
Sequence effects are said to occur whenever the problem solving performance varies as a function of the order in which problems are solved. We present a framework that explain sequence effects as a result of (a) learning during solving a problem and of (b) transferring the learned content on succeeding problems. In two experiments we studied the ambiguous influence of surface similarities among structurally dissimilar knowledge-rich problems on sequence effects. These experiments demonstrate tha

Using e-mail to support reflective narration
This article presents an exploratory study of e-mail use for reflective narration. Narration is viewed from three perspectives: the narrating act, the narrative statement, and the story. These perspectives are used to characterize the 69 e-mails that were exchanged between 13 groups of children from three primary schools. The findings show that e-mail narration has monologic and dialogic qualities, and leads to cognitive and personal reflections on the learning task. We conclude that e-mail can

Researching classroom interactions: A methodology for teachers and researchers
Teaching and learning in schools is a complex social process which involves both the teacher and students in distributed knowledge-building activities. Research into this process includes researchers exploring from the outside and teachers exploring from the inside (Bassey, 1995). Jaworski (2003) draws on the work of Wagner (1997) to elaborate a form of research which she calls co-learning, in which research on classroom learning is “conducted jointly by outsiders and insiders” (p 250).

Flexibility in macro-scripts for computer-supported collaborative learning
In the field of computer-supported collaborative learning (CSCL), scripts are designed to support collaboration among distant learners or co-present learners whose interactions are (at least partially) mediated by a computer. The rationale of scripts is to structure collaborative learning processes in order to trigger group interactions that may be rare in free collaboration. Fixing the degree of coercion is a delicate design choice: too rigid scripts would spoil the richness of collaborative in
