I love taking these courses as it reminds me [as an instructor] of things I can include in my classes to enhance the students' experience as well as lessen my load. The idea of creating a specific document (outside of my already posted Office Hours) can minimize students writing at 11:50 PM on the night an assignment is due, expecting an immediate response. In upcoming classes I am going to email and post a note as to when I am online specifically. Though it may vary, there are times I know for sure I am online, including during the early hours of a day when assignments are due. Specifically stating this may help with those last minute requests, that I never can get to. Has anyone tried this? How did it work for you?
