A lot of schools are envisaging the Apple iPad "in the roles that PCs
formerly occupied," says Scottish teacher and tech coach Fraser
Speirs. The laptop trolley becomes an iPad trolley. The checkout
computers become the checkout tablets. But that's not how the iPad is
designed, he says, and "the iPad is an extremely uncomfortable fit
for those roles defined in an earlier era." But it can be a hugely
helpful learning tool in the digital era, as Speirs is learning in a
schoolwide experiment that has garnered worldwide attention. See what
