Welcoming students and giving the course a personal touch is central for online courses. A brief introduction video makes the course less anonymous and gives you the opportunity to set the tone for the course.
There is no fixed template or a "must-do" for an introduction video, rather, you can show yourself in a way that you feel comfortable with, so students get an authentic impression of you and the course.
Suitable in every course.
MIDI: These tips are also suitable for current teaching situations, but require a little more preparation. - Prepare coarsely what you want to say. - Video recording + editing: 15-20 min. - Uploading the video in your courseware introduction section.
