Professionalism
I used the Oasis platform to find OER content for topics on Professionalism. Professionalism, being a broad topic, I like how there were various categories available to sift through to find the topic I was looking for a lot faster. It also opened my eyes as to what other disciplines besides mine use professionalism and even found a course on Computer Sciences where professionalism is key: Ethical Practice: Leading Through Professionalism, Social Responsibility, and System Design.
