Coleen,
So much of what you stated is at the heart of all good teachers. Your dedication to the student's well-being is evident and commendable. Do you have a preferred way to reach out to an online student who will not reply to emails, phone calls, text messages or outreach to them via social networking sites? Many instructors have indicated they struggle to identify additional (beyond the mentioned four) ways to reach out to these students. Thank you very much for your contribution.
