I noted one of the program sessions here ( https://itc.eventbank.com/event/2019-elearning-conference-9914/program-agenda.html ) which did not include the “AND Maintain…” notation.
Several years ago, I found an online OER for an Introduction to Psychology. I asked the author if I could port the content over from his format into a WordPress site. It ported fairly easily.
At a later date, I came across course materials for a different course and over time realized that one of the pitfalls of using OER, or developing OER content was that it is exciting when you first start developing the materials, and even so the first time you teach with it, but then boredom sets in… the second or third time you teach, and then you need to start updating those once exciting materials, and then it is not as exciting anymore, so you start looking for a graduate student to perform the task of updating existing materials. *That may be jaded, but pay attention and I think you will find that at least some developers of OER content will repeat this pattern.
So, what if your institution adopts OER materials. Maybe, you are part of a group at your institution who are responsible for choosing, adopting and adapting OER content. If two faculty teach with this material, do you control any new content they might specifically add to their course? When it comes time to update these OER materials, who gets assigned the task(s) of content maintenance?
