I'm always interested in new ways of describing things to perhaps give greater clarity.
Stock and flow by Lee Lefever (mentioned in Harold Jarche's blog) is a way of describing digital media contrasts the products or finished entities of stock with the interaction and communication of flow. YOu need flow for context, flow for the learning conversation. Jarche characterises Open Education Resources as the stock. For the flow, you need the teacher.
Thinking about the current predicament of Higher Education, fighting against the openness, fighting against the freedom and the knocking down of the walls. Its useful to show that having open content need not destroy everything they own of value. The message is very clear:
If you teach well, then it is of value to learn within your institution.
If you present content and call it teaching, then it is not.
If there is only stock - get some flow.
Unfortunately, I can't see myself talking about stock and flow in my Higher Education institution. It wouldn't work.
