Re-shaping Post-COVID-19 Teaching and Learning: A Blueprint of Virtual-Physical Blended Classrooms i n the Metaverse Era

During the COVID-19 pandemic, most countries have experienced some form of remote education through video conferencing software platforms. However, these software platforms fail to reduce immersion and replicate the classroom experience. The currently emerging Metaverse addresses many of such limitations by offering blended physical-digital environments. This paper aims to assess how the Metaverse can support and improve e-learning. We first survey the latest applications of blended environments in education and highlight the primary challenges and opportunities. Accordingly, we derive our proposal for a virtual-physical blended classroom configuration that brings students and teachers into a shared educational Metaverse. We lOcus on the system architecture of the Metaverse classroom to achieve real-time synchronization of a large number of participants and activities across physical (mixed reality classrooms) and virtual (remote VR platform) learning spaces. Our proposal attempts to transform the traditional physical classroom into virtual-physical cyberspace as a new social network of learners and educators connected at an unprecedented scale.

Tips, Tidings, and Tech: Governmental Communication on Facebook during the COVID-19 Pandemic

The COVID-19 pandemic led governments to rely on the versatility of social media to communicate with their citizens. This paper analyzes the Facebook communication of political leaders and health departments from 17 countries during the COVID-19 pandemic. We evaluate the citizen's response under the frameworks of media richness and user engagement. We note that governments and leaders communicate primarily through richer media (photos and videos), despite a negative correlation between media richness and user engagement. Plain-Text messages posted by country leaders attract the most engagement, while their COVID-19 communication tends to generate lower engagement. On the other hand, health departments' pages experienced a sharp increase in engagement around COVID-19 communication as citizens sought information during the pandemic. Finally, topical analysis shows that Discussions and Co-Use of COVID-19 with other topics can boost citizens' engagement. Our comparative analysis shows practical implications for social media users and social media designers. Our findings can help governments and organizations design effective social media communication during crises. © 2022 ACM.
