Prezi presentations are a fantastic replacement for or addition to Powerpoints and other more standard presentation material in the classroom. The fluidity or "zooming" nature of these presentations appeal to students sense of novelty, and I have often had literal "oo"s and "ahh"s coming from my students over topics as dull as grammar, rhetoric, and mechanics. This is no small task.
This prezi covers the main philosophers of the Enlightenment period and represents a very simple use of the Prezi software (see my other Prezis if you are looking for more interactive and sophisticated presentations). Whether you are introducing them to it for exposure or plan to use it in conjunction with other materials to connect with your literary or historical unit, this presentation is a straightforward way to engage with the philosophers Rousseau, Kant, Montesquieu, Locke, and Hobbes. Each philosopher includes a brief look at their most famous work, the main ideas from that work, and the implications of those ideas. As a bonus, the underlined portions of the notes make a mini lesson for students on the importance of being able to pull out only the main ideas of notes presented and to avoid writing down everything on the screen (something my students struggle with).
Although I use it with my SMARTBoard, the prezi only requires that you have a computer hooked up to some sort of projector for the students to see, and because there are no embedded videos, it does not require internet access.
