<p>The only real issues I have had with online communication is the motivation to interact. The students I typically have (IT students) enjoy the isolation and prefer to work alone. Getting them to interact with discussions and group projects has helped in this. I like the use of Packet Tracer and creating a multi-networked group project or using Visual Studio and having them create different modules and discussing how to get them to work together. The same can be done for any group project and what is nice is that the LMS allows for grading individually or as a group.</p>
