Re: Time lockdown will last?
A mixture, actually. Learners can log into the virtual classroom and access worksheets, quizzes and videos, but there's also a lot of teaching going on via Zoom. They've been submitting assignments via online dropboxes for years, in any case, and we have MS Office 365 so all learners can access versions of the standard Office software. It's a work in progress, helped by the fact that a lot of the big edtech companies are offering their services for free.
