I'm not suggesting simply throw out what has been done before and replace it with modern methodology. I am saying use modern science of learning to inform what we are doing as teachers in the dojo. I'm primarily a koryu budo guy, the really old stuff, and I use a classical pedagogy when I teach koryu budo. However, I inform that with understanding of things like how much information an individual can retain at one time, and I build my classical style class around the facts of human learning and mind capacity.
