I worry about one of the new approaches becoming the entrenched standard and seeing some people get left out due to their learning style. That doesn't have to happen, but it seems to be the way public education works. In college I would try to find an online version of whatever class I was taking's lectures. I could usually find a good lecture by a professor from one of the best schools in the land, sometimes I could find a lecture from the author of my text book. If I had to rank what I learned the most from it would look like this. 1. The internet. Get 7 different versions of the same concept in the time it takes to listen to a lecture. 2. In class Lecture, discussion with friends. 3. Text book. I've had so many classes where I wouldn't have even opened the damn things up if there was a problem or data set I needed. Not all are bad, probably about 40% have been rendered totally useless by the internet.
