More than 500 educators and experts from around the world recently attended the iPad Summit at Harvard Medical School, where the focus was on the use of the Apple tablet computer as an educational tool. Teacher Jennifer Carey blogged about her experience at the conference, which she called "one of the most innovative and exhilarating experiences I have had as an educator." Her three takeaways include that the iPad is just a tool, professional development must follow iPad integration plans and the device must do more than replace other systems such as laptops.
