Adan Sanchez-Uribe is high-tech. Bilingual. Hard at work on his first e-book.

And he's 5 years old.

With one finger - sometimes more - the Nashville preschooler takes pictures of his classmates, draws around them on the touchscreen, types his name, records his voice and plays it back right away.

Before class ends, he shows off the e-book to his teacher and classmates. Given a little more time, a much broader audience will take notice.

That's because Sanchez-Uribe plays with the iPad in one of two city classrooms being studied to see how preschoolers learn with digital tablets.

It's an innovative approach in Tennessee at a time when interest in the state's preschool classrooms could hardly be higher.
