I taught this course at the University of Georgia as a PhD student. Because of the large size of the course, I trained a head TA and a team of other TAs to run labs and grade papers.
At the time, I designed and coded the Web platform running the course in PHP; the platform design templates are stiil being used (see this link) though the interactive elements have been removed. I had built in secure socket layer security and passwords to ensure safe access to protected content including statistics on the course grades, movies, etc.
We see interesting devices from time to time that prompt re-thinking the potential of how we behave and what we are able to do. I saw an interesting USB key fob today that did just that. It is a small device that will enable a person to carry files along with an identity and interaction method! What does this mean?
