Thayer Method vs Flipped Classroom?

I'm not in the military nor had I heard the term "Thayer Method" before today. How is the "Thayer Method" different than "Flipped Classrooms?" And, if there is no difference, then why is flipping a classroom not called "Using the Thayer Method?"

Feel free to answer on the blog, reply to Twitter or respond on Facebook. I'll compile answers in another post at a later date.

Thanks for playing along!

(psst, I am also testing new ifttt recipes with this post)
