Regarding the design of the Head First series, neither Kathy nor Bert have education degrees, Kathy's degree is in physiology and then she later switched to programming. Bert does say that he talked to teachers over the years while developing his philosophy of pedagogy, but so have a lot of people.
If you are saying that Kathy and Bert are educators because they educate, then I agree, and that was my point in saying that obviously Khan Academy is populated by educators.
he talked to teachers over the years while developing his philosophy of pedagogy that's actually exactly what I am advocating. I am all for subject matter exports being the people on the stage, but they need to be informed of the basics behind learning. There are many great online lectures, but finding ways to add repetition without simply watching the same video again is critical.
PS: Funding is clearly an issue, but there is a long history of education and some extremely valuable lessons have been learned the ridiculously expensive way. Leveraging that history does not take a lot of resources just a willingness to use them.
