A teacher's role may vary among cultures.
Teachers may provide instruction in literacyand numeracy, craftsmanship or vocational training, the arts, religion, civics, community roles, or life skills.
Formal teaching tasks include preparing lessons according to agreed curricula, giving lessons, and assessing pupil progress.
A teacher's professional duties may extend beyond formal teaching. Outside of the classroom teachers may accompany students on field trips, supervise study halls, help with the organization of school functions, and serve as supervisors for extracurricular activities. In some education systems, teachers may have responsibility for student discipline.
Teaching is a highly complex activity.[2] This is in part because teaching is a social practice, that takes place in a specific context (time, place, culture, socio-political-economic situation etc.) and therefore reflects the values of that specific context.[3] Factors that influence what is expected (or required) of teachers include history and tradition, social views about the purpose of education, accepted theories about learning, etc.[4
