How I Use It
I use Prezi as an assessment tool. Students research and then create Prezis to demonstrate their knowledge of a topic. Sometimes we present with them, as you would with PowerPoint and sometimes they are end-user driven.
Prezi is a great way for students to demonstrate knowledge through presentation. They can work individually or in teams. Because it is cloud-based, they can work from school and then seamlessly access their work from home. One note is that you need an email address to create an account, which can be an issue for using it with lower grade students. I get around this by creating a class gmail account and have everyone log in with that email account. This might not work in all situations, but it works for me.
