I would not use the flip camera. There is not really anything about it that makes it better than another piece of technology. A digital camera or even something like an ipad has the same quality of video recording along with much more. The only benefit I see that the flip camera has over other similar technologies, is that the thumb drive is right there, making it easy to load to a computer. Other than that one plus, I think it is a waste of money and technology resources.
To use most of this technology, I would want to practice with it to master it and decide the best way to use it in class. I would use the smart board and wolf vision tomorrow, because I feel like I am most familiar and comfortable with these. The smart board is very basically a way to combine a white board and a projector connected to a computer. I could easily incorporate that into a classroom tomorrow.
I would use the smart board as a way to brainstorm paper ideas with students. After we brainstorm (and I write the ideas on the smart board) I could save the ideas to my computer and compile a list for students. Students would not need to take notes, but could instead be fully engaged in coming up with ideas while I take notes for them. Given more time, I would love to come up with more ways to use much of these technologies in my own classroom, because I think they have a lot of potential benefits.
