I teach math and currently I use the computer in the classroom, showing powerpoint slides, and then writing on them using the StarBoard--a smaller white board. I can then save these as jpg's and post them on my class's website. We are looking at writing a grant to get instructors iPads to use in the classroom. My questions, if anyone can help, are: 1. Can I use the iPad like an HP tablet, walking around the room, having what I write on the iPad show up on the overhead monitor? 2. Will I be able to annotate my slides as I show them, working out the problem and saving my notes? 3. Is there a good stylus that will work? Right now, the StarBoard's pen is 'shaky', and my handwriting looks like some little 'kid' wrote it. If anyone has used the iPad in this manner can you let me know how it goes? Thanks in advance!
