"Official" distance learning resources from CA Community Colleges
This page from the California Community Colleges has a lot of different tips and advice for transitioning your classroom online. It covers planning the transition, communicating with students, organizing your course content, and how to support your students.
You’ll find ways to break your course up into manageable chunks, to create quizzes and discussions online, to keep students engaged when doing work on their own, and which of your materials can work for distance learning so you don’t have to reinvent the wheel.
There is also a complete schedule of webinars available through the community colleges.
