Once I make a commitment to facilitate online course, I am committed to 7-day course presence. I am an early person so my interaction is usually in the morning—I make sure to tell students. One way I interact with students is through the discussion threads. I usually take the initiative to start contributing to the discussions on Sundays (lessons starts on Mondays). I do not respond to each post students make, but rather every other post along with posting questions related course subject matter being discussed that week. Would be interested to know your approach to course discussions; what is your level of contribution.
