Last year, I've been on a learning binge myself, due to the fact that I want to understand the underlying workings of the technologies that are shaping our near future. In this interest, I have taken what little time I have (with a job and two children) to relearn the baseline college mathematics that I've lost from my apathy towards serious continuing education. I first completed the course "Learning How to Learn" and applied the practices within to courses in Calculus and Physics. I'm close to completing Single Variable Calculus on the OCW website on MIT.
I was never a great student, and it could be just because, as I think I've discovered, I'm just a slow learner. My early educational talents and successes were due to a lot of early reading that I did, but it's clear to me that it takes a lot of repetition before I start to understand a subject, and I often have to go back over lectures, then read the associated notes, and run through a ton of practice problems (which I then put into anki) before I grasp a subject. Due to this my learning has been slow (along with the two kid situation), but I'm certain now that I have a much better grasp of the subject matter than I did when I was twenty. I'm not suggesting I'm smarter with age, what I am suggesting is that I didn't have study habits that allowed me to flourish.
Clearly, the current educational models that we are using in our schools are failing students like me who get a good head start due to early reading, but can't learn fast enough to keep up in a classroom environment. It is clear from what I've learned about the learning process from Barbara Oakley and others that the actual processes that we put in place are further suboptimal for the learning process, but the ways that we set up our education system are not the result of experimentation. If I were to surmise their source, I would say that they are explicitly designed to fail, so that we can excuse reduced spending in public education systems.
Still, these self-study courses are great for people like me, as long as you are permitted to study at your own rate. This is important as I'm going to guess that perserverance is as important as intelligence when it comes to advancing to the point where you can aid research teams. I predict that nations that automate educational models (as well as hiring a broad staff of educators, lecturers, and tutors) that are successful will have a much larger impact on the future of the information age than they did in previous eras.
