"Huh?", "Hey!", and "Oh."

Good day at the dojo. Worked with lower Kyus on up to a San Dan and a Yon Dan. Some interesting concepts, bunkai, applications were studied. Some people ‘got’ some ideas right away, others had to struggle grasping them.

I realized that what one person may find easy another person may find difficult. Learning seems to boil down to three words: "Huh?", "Hey!", and "Oh."

A student may feel something isn’t right, but doesn’t know what to do about it … or they may not even realize there’s a problem with what they’re doing: “Huh?”
A student may understand the correction, have an 'aha' moment, or even better, discover something on their own: “Hey!”
With understanding, the problem can be fixed, the knowledge becomes ‘matter of fact’, and can be routinely applied to other situations: “Oh.”
