What is the best ability of an online teacher? To me, the answer is simple. The best ability is AVAILABILITY. Your students should feel your presence mind, body, and soul:
Mind: Don’t be the absent-minded professor! You should be completely focused on your students when you are working with them. Your online students should never feel like a burden.
Body: You have to be a constant presence in your online courses. Your online students should never feel like they are alone.
Soul: You should love students, love content, and love bringing the two together. Your online students should be able to feed off of your energy.
