Towards a generic platform for developing CSCL applications using Grid infrastructure

The goal of this paper is to explore the possibility of using CSCL component-based software under a Grid infrastructure. The merge of these technologies represents an attractive, but probably quite laborious enterprise if we consider not only the benefits but also the barriers that we have to overcome. This work presents an attempt toward this direction by developing a generic platform of CSCL components and discussing the advantages that we could obtain if we adapted it to the Grid. We then propose a means that could make this adjustment possible due to the high degree of genericity that our library component is endowed with by being based on the generic programming paradigm. Finally, an application of our library is proposed both for validating the adequacy of the platform which it is based on and for indicating the possibilities gained by using it under the Grid.Peer ReviewedPostprint (published version

Biometrics for Authentication/Monitoring Academic Integrity: Surveying ERAU-W Student Acceptance and Insights

A confidential survey, mirroring a previous study, was used to investigate the effect of demographic differences in ERAU-W’s student body on authentication/monitoring – directly applicable to Ignite as it relates to remote modalities. Over 8,000 randomly selected ERAU-W students – both graduate and undergraduate – were invited to participate. After an introduction, with definitions and basic concepts, students answered 11 questions online. The study attempted to differentiate between student acceptance of biometrics for academic integrity as implemented by the University and the same implemented by a third party partner. Additionally, the study investigated differences in perception of video/audio-based monitoring versus non-visual sensors. The author investigated correlations between age, military status, gender, and graduate/undergraduate status, respectively, and the specific preferences expressed in the survey. The selected sample of ERAU-W’s student body exhibited negativity toward third party implementation, but not with the same intensity as the previous study. Students revealed a predilection for fingerprint-based biometrics over video/audio monitoring

Distributed Learning System Design: A New Approach and an Agenda for Future Research

This article presents a theoretical framework designed to guide distributed learning design, with the goal of enhancing the effectiveness of distributed learning systems. The authors begin with a review of the extant research on distributed learning design, and themes embedded in this literature are extracted and discussed to identify critical gaps that should be addressed by future work in this area. A conceptual framework that integrates instructional objectives, targeted competencies, instructional design considerations, and technological features is then developed to address the most pressing gaps in current research and practice. The rationale and logic underlying this framework is explicated. The framework is designed to help guide trainers and instructional designers through critical stages of the distributed learning system design process. In addition, it is intended to help researchers identify critical issues that should serve as the focus of future research efforts. Recommendations and future research directions are presented and discussed

Almost Like Being There: Embodiment, Social Presence, and Engagement Using Telepresence Robots in Blended Courses

As students’ online learning opportunities continue to increase in higher education, students are choosing not to come back to campus in-person for a variety of personal, health, safety, and financial reasons. The growing use of video conferencing technology during the COVID-19 pandemic allowed classes to continue, but students reported a sense of disconnectedness and lack of engagement with their classes. Telepresence robots may be an alternative to video conferencing that can provide learning experiences closer to the in-person experience, which also provides a stronger sense of embodiment, social presence, and engagement in the classroom. This study explored the use of telepresence robots in four undergraduate, humanities, blended learning courses. Sixty-nine students, 43 in-person and 26 remote students, were surveyed using the Telepresence and Engagement Measurement Scale (TEMS) and provided written feedback about their experience. The TEMS measured embodiment, social presence, psychological involvement, and three indicators of engagement: behavioral, affective, and cognitive. Embodiment and social presence were positively correlated as were embodiment and behavioral engagement. There was no significant difference between the two groups’ perceptions of social presence but there was a significant difference between groups’ perceptions of engagement. Qualitative data and effect sizes greater than 0.80 supported the reliability and validity of the TEMS instrument as a measurement instrument for future study of blended learning environments using remote tools such as telepresence robots. Provided that technological issues such as connectivity and audio and video quality are addressed, telepresence robots can be a useful tool to help students feel more embodied and socially present in today’s blended learning classrooms

Pedestrian Detection with Wearable Cameras for the Blind: A Two-way Perspective

Blind people have limited access to information about their surroundings, which is important for ensuring one's safety, managing social interactions, and identifying approaching pedestrians. With advances in computer vision, wearable cameras can provide equitable access to such information. However, the always-on nature of these assistive technologies poses privacy concerns for parties that may get recorded. We explore this tension from both perspectives, those of sighted passersby and blind users, taking into account camera visibility, in-person versus remote experience, and extracted visual information. We conduct two studies: an online survey with MTurkers (N=206) and an in-person experience study between pairs of blind (N=10) and sighted (N=40) participants, where blind participants wear a working prototype for pedestrian detection and pass by sighted participants. Our results suggest that both of the perspectives of users and bystanders and the several factors mentioned above need to be carefully considered to mitigate potential social tensions.Comment: The 2020 ACM CHI Conference on Human Factors in Computing Systems (CHI 2020

Transforming pre-service teacher curriculum: observation through a TPACK lens

This paper will discuss an international online collaborative learning experience through the lens of the Technological Pedagogical Content Knowledge (TPACK) framework. The teacher knowledge required to effectively provide transformative learning experiences for 21st century learners in a digital world is complex, situated and changing. The discussion looks beyond the opportunity for knowledge development of content, pedagogy and technology as components of TPACK towards the interaction between those three components. Implications for practice are also discussed. In today’s technology infused classrooms it is within the realms of teacher educators, practising teaching and pre-service teachers explore and address effective practices using technology to enhance learning

Teaching and learning in virtual worlds: is it worth the effort?

Educators have been quick to spot the enormous potential afforded by virtual worlds for situated and authentic learning, practising tasks with potentially serious consequences in the real world and for bringing geographically dispersed faculty and students together in the same space (Gee, 2007; Johnson and Levine, 2008). Though this potential has largely been realised, it generally isn’t without cost in terms of lack of institutional buy-in, steep learning curves for all participants, and lack of a sound theoretical framework to support learning activities (Campbell, 2009; Cheal, 2007; Kluge & Riley, 2008). This symposium will explore the affordances and issues associated with teaching and learning in virtual worlds, all the time considering the question: is it worth the effort
