These days we have to be enclosed in our houses by the coronavirus (COVID-19), so in my University (in Granada) as the others in Spain, we had to became in online teaching expert in a weekend.
For the courses we have following different approaches: Additional written material, several short videos about the materials, or conferences for giving the courses by video-conferences. All options have its advantages and drawbacks.
