We are having similar discussions and while we haven't written anything here are a few of the phrases that keep being heard:
"Let them use the technology they already have in their pocket." paraphrase of Will Richardson.
"student centered mass customization" based on some of the ideas in Disrupting Class, and paired with our use of Google Apps, we are saying let the kids choose whatever it is that works best for them and their family. phone, netbook, ipad, computer, or any combination, they choose the device or devices, and we say what it is we want them to do. My son "checked out" a book from the school library for the kindle reader on his ipad over the break, that's the type of service we aspire to provide.
information appliance vs production machine. I think it's pretty clear that phones will quickly replace computers as the place people (certainly students) deal with email, calendars, and even short written pieces. Again Google Apps allows us to move from one device to another pretty seamlessly. I see laptops and computers as hubs where we work on major projects, video, audio, even lengthy essays but other tasks get done on the phone.
Finally, and I wouldn't place many chips on this one yet, we have a few enterprising teachers who are developing their own instructional android apps. The best one I've seen takes a riff from an MIT project and combines GPS, text messaging, youtube, and flickr to created a location-based scavenger hunt. You get a clue, get to a specific location and then receive another clue in the form of text, image, or video. The best part is the program is hypercard like in that if you can send a text, upload a video, and upload a photo, you have the tech skills necessary to create your own scavenger hunt.
Even though these ideas aren't fully baked, I hope they help. Please share your progress with this thead, and I hope to see you in Philly or D.C., are you going to either educon or NAIS?
