All those schools and universities who already offer Blended Learning Courses have little problems of moving their classes fully online. For many others, they wished they had assistance. Here are a few links and information that might help:
If you need a Learning Management System (LMS) quickly and you don’t have to worry about your students’ data being stored outside your organisation, you could choose the Google Classroom or the try-out version of Canvas (Free for Teachers). For Google you need to register your school or university for the GSuite and, needless to say, all services run on Google. Google is, e.g., temporarily rolling out free access to their advanced Hangouts Meet video-conferencing capabilities to all G Suite and G Suite for Education customers globally including larger meetings, for up to 250 participants per call and the ability to record meetings and save them to Google Drive.
For Canvas, my personal choice, you find well-organized official getting started videos. I am offering my university’s Fundamentals 2 Training Session webinar-recording (about 1.5 hrs) which gives tons of detailed insights that short YouTube Videos might miss. Canvas has published a website dedicated to Coronavirus Planning for K12 and Higher Ed.
Some more useful information: Zoom (Free Basic) is temporarily lifting the 40-minute time limit on Free Basic accounts for schools affected by the Coronavirus. However, check first if your country is on the list that is included in this offer. Otherwise, there is still the free version of ezTalks, that offers up to 100 participants but a 40 minute time-limit.
You may also like to check out Microsoft Teams to facilitate remote learning. Last, but not least, UNESCO has curated a comprehensive list of distance learning solutions.
I hope these links suffice to nudge you into the right direction. Stay healthy and my best wishes to you and your students in difficult times!
