In this work we present an input vector monitoring concurrent BIST scheme, specially designed for the testing of ROM modules.

In the literature, there has been considerable effort in the development of algorithms for composing groups as well as their evaluation. The most widely used approach is the Genetic Algorithm, as, it can handle numerous variables, generating optimal solutions according to the problem requirements. In this study, a novel genetic algorithm was developed for forming groups using innovative genetic operators, such as a modification of 1-point and 2-point crossover, the gene and the group crossover, to improve its performance and accuracy. Moreover, the proposed algorithm can be characterized as domain-independent, as it allows any input regardless of the domain problem; i.e., whether the groups concern objects, items or people, or whether the field of application is industry, education, healthcare, etc. The grouping genetic algorithm has been evaluated using a dataset from the literature in terms of its settings, showing that the tournament selection is better to be chosen when a quick solution is required, while the introduced gene and group crossover operators are superior to the classic ones. Furthermore, the combination of up to three crossover operators is ideal solution concerning algorithm's accuracy and execution time. The effectiveness of the algorithm was tested in two grouping cases based on its acceptability. Both the students participated in forming collaborative groups and the professors participated in evaluating the groups of courses created were highly satisfied with the results. The contribution of this research is that it can help the stakeholders achieve an effective grouping using the presented genetic algorithm. In essence, they have the flexibility to execute the B Christos Troussas

This paper presents a systematic literature review of personalization strategies utilized in immersive VR for educational objectives in the classroom. For the purposes of this review, 69 studies between 2012 and 2022 were analyzed in terms of their benefits, limitations and development features. The novelty of the study mainly arises from the in-depth analysis and reporting of personalization strategies as well as gamification techniques used in VR applications. The significance of this research lies in the observation that earlier studies' applications did not sufficiently incorporate adaptive learning content, indicating the necessity for more research in this field and revealing a research gap. In conclusion, as it encourages future research of this field, this study may be a beneficial reference for those interested in researching the implementation of Virtual Reality in education, including academics, students, and professionals.

A special focus is led on the potential solutions and examples of Open Education and Open Science in these regional use cases. Their analysis and comparison present insights about the developed strategies and implemented practices in the different regions worldwide. And their discussion offers opportunities and recommendations how Open Education and Open Science can innovate and improve formal education in schools, universities and lifelong learning during the ongoing COVID-19 pandemic as well as afterwards.

User acceptance of augmented reality welding simulator in engineering training

Prior research has examined the integration of AR-simulation in applications, like medical operations or aviation, showing the need for greater usability of these systems. However, research on AR integration in welding training is yet limited. It can help new welders learn effectively and be prepared to work in the industry. The motivation of this study was the ongoing use of AR in manufacturing training and its novelty is the analysis of the most significant factors affecting the actual AR system use. The main objective of this research is to evaluate the use of AR technology in welding training using an innovative model, appropriately extended to consider pedagogy and technology. The contribution of this paper is the exploration and understanding of the factors associated with the AR welding training which can lead to goal fulfillment and, subsequently, impact users’ choice. This study is based on a modified Technology Acceptance Model, extending it by two external variables (perceived enjoyment and system quality) and the sample is 200 trainees. The findings show that the external variables are predictors of perceived usefulness and ease of use. The intention to use AR simulator is positively influenced directly by system quality and perceived ease of use. The findings help AR developers enhance the quality of AR-simulation training systems to enhance users’ experience and their behavioral intention to use them.

A closer look at MOOC's adoption from a qualitative perspective

Supported by unprecedented publicity albeit based on an over-than-a decade-year-oldconcepts, MOOCs are currently facing the real challenges on their way to maturity: how does learning (should) happen in a MOOC? how does the process of educating thousands of students bundles with the use of educational material designed for classic studying models? In this paper we try to address current trends in the use of educational content by already deployed MOOCs using a general, ISO-based quality model designed for distance learning quality evaluation. A qualitative study of 11 MOOC courses reveals content usage patterns that imply a coherent, evolving strategy, yet a strategy still based on classic theories of distance education. The design of a Quality Reference Framework for the design and assessment of MOOCs is also briefly presented.
