The difference between “tuition and fees” and “total cost of attendance.”
A nice highlighting of why administrators should be pushing for OER. Unfortunately lost here is the actual cost of the remainder of the enterprise. Where do these OER resources come from? Who creates them? Who gets paid to create and maintain them? Or quite often, whose resources, time, and effort are being exploited to use them? Additionally, who on the institutional level is being paid to talk about OER, push it, educate educators about it, and help professors adopt it?
While it’s readily transparent how his accounting works in this limited example, there’s a lot more accounting and transparency that needs to be taken into account.
Let’s not take the cost and just shift it to others who are also ill-equipped to handle it.
