Education 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 education 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 education 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 educational opportunity in the informal sphere- for this reason, society subsidizes institutions such as museums and libraries. Informal education also includes knowledge and skills learned and refined during the course of life, including education that comes from experience in practicing a profession.
Education systems are established to provide education and training, in most cases for children and the young. A curriculum defines what students should know, understand and be able to do as the result of education. A teaching profession delivers teaching which enables learning, and a system of polices, regulations, examinations, structures and funding enables teachers to teach to the best of their abilities. Sometimes education systems can be used to promote doctrines or ideals as well as knowledge, which is known as social engineering. This can lead to political abuse of the system, particularly in totalitarian states and government. Education is a broad concept,it refers to all the experiences in which children can learn something. Instruction refers to the intentional facilitating of learning toward identified goals, delivered either by an instructor or other forms. Teaching refers to learning facilitated by a real live instructor. Training refers to learning toward preparing learners with specific knowledge, skills, or abilities that can be applied immediately.
