Pedagogy refers to the study of being a teacher or the process of teaching. The term generally refers to strategies of instruction, or a style of instruction. Pedagogy is also occasionally referred to as the correct use of instructive strategies. For adult humans, the methodology of teaching is called 'critical pedagogy' because of the complexity of the process and with the usage of analyses. This was later termed as andragody which incorporated the ‘art’ and ‘science’ of teaching adults.
Pedagogy can be categorized into theoretical and methodological. The first refers to the process of imparting knowledge in reference to principles and the latter refers to the method of giving instruction for the purpose of acquiring skills.
Etymologically, the term came from the Greek that means "to lead the child.
The Latin-derived word for pedagogy: child-instruction, is in modern use in English to refer to the whole context of instruction, learning, and the actual operation involved therein, although both words have roughly the same original meaning. In English the term pedagogy is used to refer to instructive theory; trainee teachers learn their subject and also the pedagogy appropriate for teaching that subject. The introduction of information technology into schools has necessitated changes in pedagogy; teachers are adopting new methods of teaching facilitated by the new technology.
