Kasthuri - I attended a session at ISTE last summer on using the iPad with Special Needs students (my oldest son has special needs) and discovered many apps that are created for "typical" learners can be adapted for students with special needs. The particular app and use in this article has (in my opinion) one huge advantage and one huge disadvantage. The advantage is price and therefore more widespread accessibility. Augmented Communicative Devices (http://www.abilityhub.com/aac/aac-devices.htm) can cost thousands of dollars. The iPad ($500-800) and app ($100) keeps the cost well below that and can give SES students with this particular need a greater chance in getting the device. The Disadvantage (in my opinion) is the FINE MOTOR skills necessary to operate the touch screen feature of the iPad. The children that I have seen who need this device to communicate have multiple issues at work that prevent them from isolating their fingers in such a way to make this a feasible way for them to communicate effectively. Some of the devices you can see in the link have distinct boundaries that account for mobility and fine motor deficiencies that make the use of the device successful to those who need that adaptation. I am not knocking the iPad for Special Needs students, simply pointing out that it is not the best tool for everyone.

I am familiar with BitTorrent, and it's interesting Chris that you came about it excited for its uses in education. But have you read or heard about the controversy surrounding it? In a nutshell- BitTorrent is a technology that allows large collections of files and data to be shared across the internet in a decentralized, peer-to-peer manner. A person who has the original files decides to share them via BitTorrent, so others can download from him/her. But as the others begin downloading the files, they also start sharing the pieces they've downloaded with the ever-growing set of new users asking for the file. BitTorrent works like a growing web- in order to download files shared via BitTorrent - you have to share the pieces you get with others. More downloaders = more uploaders as well, ensuring popular files will always be accessible. The benefits - this is cheap and decentralized, no need to pay to host the files on the web. The users who have the file are sharing the file from their own computers with others requesting it. And this can be permanent - if you host a BitTorrent to share a file, you have that sharing channel last forever (not relying on external services that cost $ or can be shut down).

BitTorrent is a really powerful technology that allows large amounts of files and data to be shared quickly with a limitless number of people. It's scalability at no cost. Could be a great tool for educators to share content across the globe in a hassle-free way. Even the folks at Khan Academy are excited to use it: from: http://blog.vipeers.com/vipeers/2008/10/bittorrent-is-a.html "For Khan Academy, BitTorrent was a natural extension for it stated mission of "a world-class education for anyone anywhere," Sal Khan tells Fast Company. Kahn was excited for activist educators to be able to download the Academy's entire portforlio, burn it on a CD, and distribute it to rural or underdeveloped areas otherwise unable to access it without a broadband connection. "I think the single most fun thing about BitTorrent," Khan adds, "is this content will never die. A nuclear bomb could hit our offices tomorrow and could take down our servers, but its going to sitting somewhere in the world on somebody's server." He added, "We don't care about monetizing the content; we just care that it gets used."
