how is the "bigger ipod touch" changing education? I mean, really, what is so great about and ipad that is changing education for better? Or are you talking about just a change in methodology and not quality?
I currently intern for a company that does e-education for probably the biggest education services vendor in the world. My team owns the test delivery engine, including on mobile platforms.
a more intuitive touch interface is always easier for students to give tests on, that and more interactive questions, more colors and realtime assistance, analytics, central and quick test dispatch, quicker assessments and well anytime access being 'mobile', tracking. Doing all that is impossible with paper based education, and only some of it is possible using desktop.
And besides, change in quality arises from change in methodology. The two are not mutually exclusive.
