Hi Margie, Your last questions puts everything into perspective. Yes, it is going to be very interesting as you get several years of the current generation out into the real world with their technological integrated learning paths. One thing we need to keep in mind is than in 1962 B.F. Skinner developed a teaching machine that was designed to take the human factor out of education. The intent was to replace all teachers with these machines within a few years. Here it is 2009 and we are still here. The human factor is still critical to the learning process but with technology we just aren't sure how much and at what level. Interesting research will be done in the next few years to look at brain processing and neural integration. Gary
