An OER Explorer is at the beginning of their OER Adventure.They are still familiarizing themselves with the concept of Open Educational Resources and have yet to determine whether they want to incorporate them into their courses.
An OER Adopter understands what OER is and are interested in finding and reusing already existing OER textbooks that can be incorporated into one of their courses.
Adapting OER is for faculty who already know how to find and adopt OER for their course, but would also like to learn how to revise, remix and appropriately attribute their own customized OER content.
An OER Creator is ready to write their own textbook or course materials with the intention of releasing the finished version under a open Creative Commons License.
