Many of us have PDAs but when I went to pick up my children from school one class was doing an outside lesson with their EDAs. I got a closer look at one of them later and I was amazed. they have GPS and a camera built in so that you can go on a field trip and record your location as well as photographing the scene at the same time. This is an amazing tool for history or ecology field trips. All of the devices are wireless but they can cost up to £400 for each one. I was just thinking what we could do with them as part of University teaching.
To use them most effectively you need powerful educational software and one example of this is the RedHalo system, which provides each student with a learning space.
