The Internet is a fundamentally interactive medium. Look in the average lecture hall and you will see students with baseball caps turned backward nodding off or on their cell phones. But peek into a computer lab and you will see students sitting up at the computers engaged in what they are doing. The difference is interactivity. We want to do something in front of a computer – not just read or watch – and online courses need to take advantage of this quality of the Internet to add interactivity to the experience. Only then are the courses matching the medium.
