I carried out a study examining faculty enthusiasm under the Creative Commons Licenses when faculty were forced to contribute their personally developed course materials to an OER repository (hypothetical situation). Faculty were randomly assigned to one of six scenario groups where they were being required by their institutions to contribute 100% of their personally developed course materials into an OER repository. The Independent Variable for the groups was the type of Creative Commons License their work was to be released under. Faculty then responded to the same set of questions and their responses were compared. The results were then discussed with ten faculty in qualitative interviews.
Naturally, there were issues of trust and fear, but some other interesting thing showed up. Faculty in the sample seemed to prefer licenses where people using the work were required to share their modifications over other licenses. The quantitative results were not statistically significant overall, but there were statistically significant differences between the groups. Qualitative interviews tended to confirm the preferences and trust issues.
