Anyone interested in educational technology should read Mindstorms and Powerful Ideas. Papert described how technology should be used in schools and also predicted most issues and trends with education today.

Papert work is also present in most educational/programming toys we see today - Scratch, Kibo http://kinderlabrobotics.com/kibo/, LittleBits, LEGO Mindstorms all owe their roots to Paperts ideas.
