Legal Protection

I had an epiphany this week regarding Copyright and Fair Use. It seems there is one potential vulnerability relative to Fair Use in the pedagogy I use. When my students prepare class presentations, I have them post the presentations to Wikispaces. The wiki is a natural fit for such a function, however, the real vulnerability, relative to copyright, is that Wikispaces is completely public. The epiphany this week was that Google Docs, while providing the functionality and benefits of the wiki, also affords a level of privacy within the learning domain. Only when the presentations are shared can they be seen by others. They may be seen by the public, but only after "publishing" and then the published URL must then be forwarded to potential viewers outside the learning domain.
