I've taught a few online classes for a state-wide community college. To say I've "taught" them is kind. I was basically a grader.
The first day of the semester they blasted the material onto the online Blackboard system and it had all the due dates and assignments. I couldn't change anything on the syllabus because the syllabus was standardized for every section across the state and so were the grading tools. This meant that when they turned in speeches (yes I "taught" public speaking online for one of the classes as strange as that sounds) and the speeches were done on terrible topics I couldn't lower their grade or tell them to redo it. When their voices had no enthusiasm at all I couldn't lower their grade because the state mandated grading tool didn't have anything that covered enthusiasm. This meant that you could take the class, do a speech that wasn't really appropriate, read in a monotone and still get an A as long as you took all the tests, had good eye contact, and met the time length and visual aid requirements.
