Sorry, finished too soon.
Where the complexity lies however is in the delivery as
- students are paying and feel they are consumers
- university accountability for results.
It is one thing to have a free online course by Coursera/Udacity online. Anyone who has completed those courses know that they have pros and cons.
It is entirely different for a UK university, funded by public funds to put its name to courses that haven't been built in line with the latest peer reviewed research and resources. And this is a very new area. I have been researching and working in this field for a long time (I work for a university, peer reviewed science journal on backend coding).
In order for material to be distributed online or physically, it needs to be organized in a way that sits comfortably within the guidelines fo usability. Portals require extensive user experience testing - through proper research designed enquiry. Units of work have to be designed specifically for online use, taking into account retention and focus levels online. All of these things seem intuitive and obvious as we all use the internet each day but actually early online initiatives from universities were disastrous. They didn't function adequately for the needs of the user and cause huge problems for the academics - we cannot just put something up online. Online we scan - we don't read, not accurately or with the precision and focus we require with academic thinking.
There are several specialist fields - learning technologists, user experience researcher, user interface researcher, backend and contend engineers, developers, web designers, graphic designers, audio and video techs, producers. Think of a TV show and what goes in to that only when it is a university it is the official expert - there can be no margin of error.
