My Master's in entirely online. My uni uses Blackboard. We're supposed to post work related to each week's readings. There's no opportunity to mix with classmates off BB and folks tend to only post what's necessary so no interaction - we don't have any online discussions.
I'm behind in my readings and have a terrible mental block and like others I'm easily distracted.
I don't do very well when I feel isolated so I don't like not having an opportunity to interact with classmates off BB.
