Meckeal Mallet is fully absorbed in his laptop, one of the dozens rolled into Donaghue Elementary's third grade classroom. Behind Meckeal is a screen where a visiting technology coordinator demonstrates how to operate Microsoft Word, step by step.

Some worry that technology has the potential to make young children too easily distracted, while others say that computers engage children like few other pedagogical tools.
