In case you haven't come across it yet, there is a very informative overview of the history of physics education in the US, starting all the way from the 1860s. D.E. Meltzer and V.K. Otero, Am. J. Phys. v.83, p.447 (2015). It is 12 pages long, and covers some of the most significant movement in physics education throughout the years. You get to see what works, and what didn't, and you see what changed, and what remained the same. Zz.
