Children will soon have a compelling new argument when begging their parents for an iPod, as the music, movie, and audio book player is about to take on a new role: educational tool. Pearson Education has just announced plans to release downloadable study guides (for use with Pearson texts, naturally) and audible review notes for exam preparation that may convince even the strictest parents to acquiesce and let the little white trojan horse into their homes. Not content with just the youth market, Pearson also revealed that it has purchased Apple's PowerSchool student information system, which is used by teachers and administrators to track student progress. No word yet on when kids can start using the "I'm studying!" excuse when told to take off their headphones in class.
