The "inverted-online-lecture-followed-by-guided-work-in-class" is the method that Salman Khan of Khan Academy fame pioneered. This was the first time technology was truly leveraged to make a leap in instruction efficiency. Salman Khan has several talks on this topic.

Sal Khan, who started Khan Academy in 2006, was a relative latecomer: "Flipping the classroom" was pioneered in part in the 1990s by Harvard physics professor Eric Mazur — and Dr. Mazur has said that it's a variation of law-school Socratic method that's been around (with pre-class reading instead of video) since the 19th century.
