A word for learning

“Why is there no word in Engish for the art or learning? Webster says that the word pedagogy means the art of teaching. What is missing is the parallel word for learning.” “I would use the noun mathetics for a course on the art of learning.” “My mathetic point is simply that spending relaxed time with a problem leads to getting to know it, and through this, to improving one’s ability to deal with other problems like it. It is not using the rule that solves the problem; it is thinking about the problem that fosters learning”
