I'm rooted in London, England, and most, if not all, universities in the UK have been delivering lectures and one-to-one tutorials remotely since mid-March. Since the lockdown started, I've tried at least four different online platforms: Zoom, Collaborate, Microsoft Teams and Google Meet. For my purposes, Teams has been the most successful as it is brilliant as an "all-singing, all-dancing" means of reaching students (file sharing, chats, one-to-one, lectures, screen sharing etc.).
I've also noticed that while some students struggle to engage through my online lectures, many have become more proactive and appreciate the interactive potential of remote lecturing.
