I came away from these workshops with lots of ideas for using iLife and iWork in classrooms. I'm particularly excited about publishing work created in Apple's iWork suite in ePub format, which is the file format supported by Apple's iBook app on iPods and iPads. You can take any Keynote, Numbers, or Pages document and then export it to ePub format under the Share menu. Then, drag that file into iTunes so that it imports into your iTune library (it goes under Books, I believe) and then sync your iPad or iPod. Under your iBook app, you'll be able to browse through your presentation or document. I knew that there were lots of possibilities for publishing in this manner, but I just haven't gotten around to exploring this concept until now. Think about having a class do group projects and then you sync all the reports to your class set of iPads, and the kids can take look at each other's work this way. Pretty nifty.
Also, keep in mind that you can drop videos that kids have created in Photo Booth or iMovie right into a Pages document. Also, consider creating project templates for kids to use that include the elements that you want for the project. For instance, make templates for journal entries, lab reports, etc.
Another thought that I think crossed a lot of participants' minds is that each kid ideally needs their own device. The price point of an iPad is reasonable, but a more compelling reason is there is so much that can be done to personalize learning on iPads. Specifically, it's ideal to have kids reading novels on iPads and along with this, taking notes and highlighting important passages. Annotations are really a personal thing... how would you handle this if classes had sets to share? if your class sets of iPads were re-synced each night to refresh for other classes and those notes were potentially erased?
