How should course content be shared between instructors? I am a PhD student at a fairly large university, and I have twice taught a 200 level course for my department. The course is a new course that I developed. All of the lecture and lab content for this course was developed from scratch. As I will be graduating shortly (fingers crossed), a faculty member is scheduled to take over this course. My question is, "should I pass my course content on to said faculty?" I am primarily concerned about passing my slides on verbatim. Some issues I am concerned about are my indebtedness to the department (I developed some content while a TA and some while an adjunct.), ownership of the slides (What rights do I have to my content?), and distribution of content (How can I prevent the material from being further distributed?). I am interested in the issue of sharing content in general and not just in this one instance. Any guidance is much appreciated!

edit - as a colleauge of mine pointed out, I think there is a power imbalance issue as well. The faculty at my university are generally disinclined to share material with graduate students. Most grad students have to develop their own content. On the other hand, grad students are being asked to pass on material to faculty.
In my opinion: Yes, you should certainly pass over all course material.

My colleague took over a course from another colleague who had left. My colleague know much less about the subject than the one who had left, so putting together a good course was a challenge for him. In theory, he had passed over all course material, but in practice, it was not very well organised, and my colleague ended up having to build it mostly from scratch.

As you have probably experienced, the first time you give a course is by far the most work, because you have to create everything from scratch. It helps enormously to have access to earlier course material. You lose very little by giving away course material. It's probably not publishable anyway — and if it is, passing it on to the next doesn't disqualify you from publishing it as a review or textbook, because passing it on is not a publication.

The only situation I can imagine where it would be problematic is if the person who you pass it on to claims it as their own and incorporates it in a review paper or textbook. But if you have any trust for the person, they won't do that, and it's much better to simply make all the course material available. Probably for the entire world.
