Andragogy is a noun that refers to the science of teaching adults.

Our word of the day combines the Greek prefix A-N-D-R-A, which means ‘man’ or ‘adult’ with A-G-O-G-Y, which means ‘teaching.’ Just as pedagogy is generally used in a context to refer to teaching children, andragogy usually refers to teaching adults.

I taught an adult education class a few years ago and I can tell that andragogy was a really big shift for me. For one thing, the students in that class were a lot less interested in coloring books.
