Education is the process of facilitating learning, or the acquisition of knowledge, skills, values, beliefs, and habits. Educational methods include storytelling, discussion, teaching, training, and directed research. Education frequently takes place under the guidance of educators, but learners may also educate themselves. Education can take place in formal or informal settings and any experience that has a formative effect on the way one thinks, feels, or acts may be considered educational. The methodology of teaching is called pedagogy.
A teacher (also called a school teacher or, in some contexts, an educator) is a person who helps others to acquire knowledge, competences or values.
Teacher education or teacher training refers to the policies, procedures, and provision designed to equip (prospective) teachers with the knowledge, attitudes, behaviors, and skills they require to perform their tasks effectively in the classroom, school, and wider community. The professionals who engage in this activity are called teacher educators (or, in some contexts, teacher trainers).
For rigorous teachers seized my youth,
And purged its faith, and trimm’d its fire,
Show’d me the high white star of Truth,
There bade me gaze, and there aspire.
Matthew Arnold, Stanzas from the Grande Chartreuse (1855), st. 12
The Self-Educated are marked by stubborn peculiarities.
Isaac D'Israeli, Literary Character, Chapter VI.
I hope we still have some bright twelve-year-olds who are interested in science. We must be careful not to discourage our twelve-year-olds by making them waste the best years of their lives on preparing for examinations.
Freeman Dyson, “Butterflies and Superstrings” in Timothy Ferris (ed.) The World Treasury of Physics, Astronomy, and Mathematics (p. 135)
