teacher

n. educator, instructor

In education, teachers facilitate student learning, often in a school or academy. The objective is typically a course of study, lesson plan, or a practical skill, including learning and thinking skills. The different ways to teach are often referred to as the teacher's pedagogy. When deciding what teaching method to use, a teacher will need to consider students' background knowledge, environment, and their learning goals as well as standardized curricula as determined by the relevant authority. The teacher should also be able to deal with students with different abilities and should also be able to deal with learning disabilities. Many times, teachers will have to do their job outside of the classroom by accompanying students on field trips. They also supervise study halls, help with the organization of school functions, and serve as supervisors for extracurricular activities. Although many people see teaching as a 9 to 3 job most teachers work well outside the school day including weekends. A fifty or sixty hour week is not uncommon with no additional financial compensation. In addition, many teachers purchase items for their students and classroom out of their own wages and (in Canada) receive no tax deduction for these purchases.
