I have not discussed Prezi on my blog but it is a web 2 tool that I use for presentations and is a nice change to the usual PowerPoints. An advantage is that you can download presentations to take with you as well as embedding videos etc into the presentation.
It is a great tool to use in the classroom for students to present their work.
I made this one about Web 2 tools used in the classroom for communicating and collaborating.
D & W Publications have simple, easy to use tutorials available for teachers and students - Microsoft Word, PowerPoint, Excel, Access, PhotoStory3 for Windows, and FrontPage. These are available for $NZ25 plus postage and handling from email@example.com. They are also available in pdf form for $150 for a school - unlimited copies may be made for use within the school OR $25 for a single copy for use.
