Prezi allows users to make a presentation that can be accessed online as well as downloaded for offline use. The most obvious instructional application would be to have students compile content, and then create a presentation. Prezi, however, could also be used as a repository for collaborative efforts in the classroom.
Some things to keep in mind:
- Questionable content is searchable
- You can embed, download, email or print it
- Prezi is public unless you pay for the right to make it private
- Tutorials are available on the web site
