2. Continuous User Identification in Distance Learning: A Recent Technology Perspective

Author

Portugal, David, Faria, José N., Belk, Marios, Martins, Pedro, Constantinides, Argyris, Pietron, Anna, Pitsillides, Andreas, Avouris, Nikolaos, and Fidas, Christos A.

Abstract

The worldwide shift to distance learning at Higher Education Institutions (HEIs) during the COVID-19 global pandemic has raised several concerns about the credibility of online academic activities, especially regarding student identity management. Traditional online frameworks cannot guarantee the authenticity of the enrolled student, which requires instructors to manually verify their identities, a time-consuming task that compromises academic quality. This article presents a comprehensive review of existing efforts around continuous user identification, focusing on intelligent proctoring systems and automatic identification methods, as well as their applicability in this domain. We conclude that there is a clear need for continuous user identification technology by HEIs, but existing systems lack agile system integration models that combine many inputs, such as face, voice and behavioural data in a practical manner, and encounter numerous barriers related to data protection during implementation.

5. Assessing Learner Facilitation in MOOC Forums: A Mixed-Methods Evaluation Study

Author

Ntourmas, Anastasios, Dimitriadis, Yannis, Daskalaki, Sophia, and Avouris, Nikolaos

Abstract

One of the main challenges of massive open online courses (MOOCs) is the effective facilitation of learners in the course forum. The more learners participating in the forum, the more difficult it is for instructors to provide timely support. The effective intervention of teaching assistants (TAs) can play a crucial role in mitigating this issue; however, questions arise regarding the instructional approaches that TAs follow and whether they can effectively promote learning in a MOOC environment. In this article, we study the instructional approaches that TAs followed in two MOOCs of different subject matters, using mixed-methods. The goal was to evaluate the pedagogies that TAs adopted in facilitating learners, following a broadly accepted framework on MOOC instructional quality. Content analysis and interviews with the TAs provided insights into their intervention strategies, while linguistic and social network analysis enhanced the findings. The study revealed that the TAs most often were rushing to provide direct answers rather than guiding learners in finding themselves an answer. Problem-solving approaches and collaboration were not adequately promoted. The findings of this article provide design implications for the development of supportive tools that could automatically assess facilitators' instructional approaches in the forum. Thus, timely feedback could be provided to instructors so as to refine the instructional design of their online courses and to provide guided support to their learner facilitators while courses are running.

Abstract

Information architecture forms the foundation of users' navigation experience. Open card sorting is a widely-used method to create information architectures based on users' groupings of the content. However, little is known about the method's cross-study reliability: Does it produce consistent content groupings for similar profile participants involved in different card sort studies? This paper presents an empirical evaluation of the method's cross-study reliability. Six card sorts involving 140 participants were conducted: three open sorts for a travel website, and three for an eshop. Results showed that participants provided highly similar card sorting data for the same content. A rather high agreement of the produced navigation schemes was also found. These findings provide support for the cross-study reliability of the open card sorting method., Comment: ACM CHI Conference on Human Factors in Computing Systems (CHI) 2019

22. Towards the Real-Time Evaluation of Collaborative Activities: Integration of an Automatic Rater of Collaboration Quality in the Classroom from the Teacher's Perspective

Author

Chounta, Irene-Angelica and Avouris, Nikolaos

Abstract

This paper presents the integration of a real time evaluation method of collaboration quality in a monitoring application that supports teachers in class orchestration. The method is implemented as an automatic rater of collaboration quality and studied in a real time scenario of use. We argue that automatic and semi-automatic methods which provide assessments of collaboration quality or detect disorders and anomalies in collaborative activities should be further used to assist class monitoring. To that end, we study the routine of teachers when they monitor computer-supported collaborative activities with respect to the size of the classroom and the support of an automatic rater. We focus on the way the rater affects their task and how it can be further used to empower the practice of teachers.

23. Learning Outcome, Presence and Satisfaction from a Science Activity in Second Life

Author

Vrellis, Ioannis, Avouris, Nikolaos, and Mikropoulos, Tassos A.

Abstract

Although problem-based learning (PBL) has many advantages, it often fails to connect to the real world outside the classroom. The integration with the laboratory setting and the use of information and communication technologies (ICTs) have been proposed to address this deficiency. Multi-user virtual environments (MUVEs) like Second Life (SL) are 3D collaborative virtual environments that could act as complementary or alternative worlds for the implementation of laboratory PBL activities offering low-cost, safe, and always available environments. The aim of this study was to compare a simple laboratory PBL activity implemented in both the real and virtual worlds, in terms of learning outcome, satisfaction, and presence. The sample consisted of 150 undergraduate university students. The results show that the MUVE provided similar learning outcome and satisfaction to the real-world condition. Presence was positively correlated to satisfaction but not to the learning outcome. Finally, there are indications that the MUVE was perceived as more pleasurable and informal learning environment, while reality was perceived as more stressful.

Abstract

The credibility of online examinations in Higher Education is hardened by numerous factors and use-case scenarios. This paper reports on a longitudinal study, that spanned over eighteen months, in which various stakeholders from three European Higher Education Institutions (HEIs) participated, aiming to identify core threat scenarios experienced during online examinations, and to, accordingly, propose threat models, data metrics and countermeasure features that HEI learning management systems can embrace to address the identified threat scenarios. We also report on a feasibility study of an open-source intelligent and continuous student identity management system, namely TRUSTID, which implements the identified data metrics and countermeasures. A user evaluation with HEI students (n = 133) revealed that the TRUSTID system is resilient and effective against impersonation attacks, based on intelligent face and voice identification mechanisms, and scored well in usability and user experience. Aspects concerning the preservation of privacy in storing, retrieving and processing sensitive personal data are also discussed. [ABSTRACT FROM AUTHOR]

30. Support for the Teacher in Technology-Enhanced Collaborative Classroom

Author

Voyiatzaki, Eleni and Avouris, Nikolaos

Abstract

This paper presents a study on the role of the teacher in computer-supported class group activities. We discuss various teacher tools that support this role. In the reported studies the students are engaged in group activities through networked computers. Typically they use a two-space collaboration tool. One shared space used for jointly producing a diagrammatic representation (concept map or other form of diagram), and one for text based communication. The group activities have a time span of typical classes: i.e. a few minutes to a few hours. In this context, we focus on the study of typical teacher actions and used representations and on the support that the tools used provided to the teacher for supervision of the class and group activities.
