In this paper we discuss applications of Bayesian networks to educational testing. Namely, we deal with the diagnosis of person’s skills. We show that when modeling dependence between skills we can get faster a better diagnosis. We also show that there exist test setups for which it is impossible to get a complete and correct diagnosis unless we model dependence between skills. We present resul...

Studies of human intelligence provide strong evidence for the neural efficiency hypothesis: More efficient brain functioning in more intelligent individuals, that is, less cortical activation in brighter individuals. The main goal of this study was to explore the relationship between intelligence and cortical activation in combination with a cognitive training. In 83 participants, cortical acti...

Although conventional tests are often used for determining a student’s overall competence, they are seldom used for determining a finegrained model. However, this problem does arise occasionally, such as when a conventional test is used to initialize the student model of an ITS. Existing psychometric techniques for solving this problem are intractable. Straightforward Bayesian techniques are al...

Research has established that individual student interest has a positive effect on learning and academic achievement. However, little is known about the impact of a blended learning approach on individual student interest and whether combinations of online and face-to-face learning activities significantly enhance student interest. This paper assesses the effect of blended learning on perceived...

Several alterations in the software design would sometimes result in the failure of the system which has been operating effectively, meeting all the specifications at that point in time. In order

Background: The TIME framework was developed by the International Advisory Board for Wound Bed Preparation (WBP) (Schultz et al, 2003), as a practical tool for use in the clinical setting and summarises the four main components of WBP: tissue, infection/inflammation, moisture, edge. Aims: To examine the impact of delivering an educational programme using the concept of WBP and the associated TI...

An important recent finding is that testing improves learning and memory. In this article, the authors describe a demonstration that illustrates this principle and helps students incorporate more testing into their learning. The authors asked students to read one text using a Study–Study strategy and one text using a Study–Test strategy. One week later, the authors tested students’ memory for b...

Test and qualification (T&Q) phases take a significant portion of the time to market for critical products in space industry, especially when introducing new technologies. Since T&Q are treated as standard procedures, they tend be independent architectural design kept away from decisions. However, technologies, procedures may differ those established regular scenarios, estimation costs duration...

We investigated the common difficulties that students have with concepts related to rotational and rolling motion covered in the introductory physics courses. We compared the performance of calculusand algebrabased introductory physics students with physics juniors who had learned rotational and rolling motion concepts in an intermediate level mechanics course. Interviews were conducted with si...
