This is a great video on a general overview of how a teacher can use technology to revolutionalize how students access and interact with information. Instead of a text book, students are expected to create their own text book, and interact with the creators of the writers of the various blogs and sites that make up the body of information they create.
Perhaps you'll see a lot of things that you are already doing in your classroom in this video. Hopefully this video will inspire you to take technology in your classroom to the next level. Instead of adding a little technology in, let the technology completely change the way you "do class". It's not about requiring students to create a powerpoint every now and then, it's about introducing them to a global, constantly changing body of knowledge that hopefully, they'll utilize for the rest of thier lives.
