The term Pedagogy and pedagogue come from the Greek paidos ‘boy, child’ plus agogos ‘leader.’ We tend to usually say something is ‘pedagogical’ if it is easy to understand and teach. The underlying assumption is that if it is easy for children it is easy for adults to learn.
But the thing is adults and children don’t learn the same way. There is another similar word ‘Andragogy’ that describes how adults learn.
