What are you thinking of? What are the big advances in education that have been made in the past few decades? I have kids in high school right now and I can say they are learning things earlier than I ever did. They have a lot more pressure on them as well. I'm not certain that's a good thing though.
As far as technology goes, I don't see much change other than acceptance of it. My kids are encouraged to use their cell phones productively (calendar, communication, camera, etc...). But the process of education itself seems about the same as it always has been. Gains certainly haven't been exponential.
