<unk>  encompasses both the teaching and learning of knowledge, proper conduct, and technical competency. It thus focuses on the cultivation of skills, trades or professions, as well as mental, moral & aesthetic development.
Formal<unk>  consists of systematic instruction, teaching and training by professional teachers. This consists of the application of pedagogy and the development of curricula. In a liberal<unk>  tradition, teachers draw on many different disciplines for their lessons, including psychology, philosophy, information technology, linguistics, biology, and sociology. Teachers in specialized professions such as astrophysics, law or zoology may teach only in a narrow area, usually as professors at institutions of higher learning. There is much specialist instruction in fields of trade for those want specific skills, such as required to be a pilot, for example. Finally, there is an array of<unk> al opportunity in the informal sphere- for this reason, society subsidizes institutions such as museums and libraries. Informal<unk>  also includes knowledge and skills learned and refined during the course of life, including<unk>  that comes from experience in practicing a profession.
