One tip was "Teachers are using the hashtag #virtualschool on Twitter to share resources."
Other tips from https://www.edutopia.org/article/what-teachers-china-have-le... were
-- Start by continuing to use lessons that are clear and simple, and don’t introduce new programs for teachers and students to learn if you can help it.
-- When building digital lessons, it’s helpful to reduce the number of external links on your online learning platform. For example, if you want students to read an article, it’s safer to upload a PDF (to OneDrive or GoogleDrive), rather than a link to an external site that may or may not work.
-- Many of our classes at school intentionally used workbooks and paper-based tasks instead of laptops to reduce students’ screen time.
