A teacher is someone who teaches or trains others. This can include a traditional schoolteacher who teaches children, but also includes people who teach adults, such as college professors or instructors at a vocational school.
A teacher is most of all a facilitator. It is someone who shows others how to find helpful tools in order to solve problems or carry out different tasks. It is someone who helps others be more self-sufficient.
A teacher is the person who runs a classroom and teaches you the material for your course. They are also the person to make and give you tests that will evaluate your performance in the course.
A teacher should be a role model to the students. He should be well prepared before teaching his students and knowledge sound is must to him. A teacher duty is not only to teach but to interact with students.
