Using cameras was something that I thought would have been much too big of a liability. I realized that frame of mind was a product of me being a little bit of a "digital immigrant". Digital cameras are actually rather affordable. It wouldn't be too hard to get enough money in grants for a classroom to have a couple cameras.
Moreover, if we set up good procedures and guidelines, the students will know how to handle the cameras, so they will be safe. I think that with technology teachers have to show a lot of trust, but also have to have high expectations, as well as be strict.
I felt like an assignment like this is particularly valuable, because the student is required to look for things they are learning about in class out in the real world.
