Are there any resources good for finding out more about this and such studies? Myself, I went through this process in physics, and in many cases it was years afterwards that I properly understood the implications and context of the early courses, and only through repeat exposure could grok the actual connections in the problems. It seems especially hard to test and evaluate something that is planting the seeds for a more complete understanding, maybe years down the line.
