Check out this article for ways to use Prezi as a platform that extends beyond a presentation tool:
If one looks past the presentation use case, the combination of the flexibility of a nearly infinite digital canvas and easy-to-use design features makes for a powerful and highly accessible tool for developing thought maps, prototyping designs for digital interfaces and physical spaces, creating bespoke visualizations, and as a platform for comparative visual analysis and annotation.
In Tech Comm, have students create their definition/description assignment in Prezi, using it to annotate and analyze visual representations. Likewise in Intermediate Comp, students could also visually represent arguments, creating texts that analyze how people/groups define the terms of an argument.
