If it is a good course on business communication they _should_ be doing it - in class. And getting feedback and suggestions on improving with every attempt.
Internships are a wonderful thing but many people don't realize how they are coming across so don't look to improve. There is some learning by osmosis, but mostly people keep doing what they have always done because it works (as far as they can tell).
They won't be doing it, they will be doing a simulation of it. How are they going to learn business communication without doing it in the context of a real business with a real P/L line and real consequences for good and bad execution?
