How I Use It
I use Prezi to create presentations for instructional purposes. They are engaging and students really pay attention to it. I use it and create "slides" or views that have blank areas and have students come up to the interactive whiteboard to respond using the desktop annotate tool. I do not have students create with it yet, as you have to have am email address to sign up, but do encourage them to try it at home with their parents. I like to focus on an image or a word that is the focus of the lesson. I then find areas that are pertinent to the instruction and zoom in on that spot to reveal the information that is "hidden" in the word or image. I sometimes do it in reverse to keep students guessing the "main idea" of the lesson as I am introducing the topic during the exploration. There are many ways to achieve the desired effect.
Prezi is a presentation tool that is not your average PowerPoint presentation. It pans, zooms, rotates, and can be a bit busy. But it will catch your attention. Some of the best presentations I have seen have been created in Prezi. The ability to have movement in your presentation is an attention grabber and keeps students attention. Can it get a little to busy, yes. Balance is key in this application. Looking at the examples is a great way to see the most effective ways to make a dynamic presentation.
