Pedagogy is the discipline that deals with the theory and practice of education; it thus concerns the study of how best to teach. Spanning a broad range of practice, its aims range from furthering liberal education (the general development of human potential) to the narrower specifics of vocational education (the imparting and acquisition of specific skills).
Instructive strategies are governed by the pupil's background knowledge and experience, situation, and environment, as well as learning goals set by the student and teacher. One example would be the Socratic schools of thought.
The teaching of adults, as a specific group, is referred to as andragogy.
