Teacher’s Profession When young people choose the profession of a teacher, it is always necessary to bear in mind that teaching is a very difficult job. It implies great responsibility and a lot of activities of different kind both in class and at home. There are always a lot of copybooks to be corrected, plans to be written, and problems to be discussed. In fact, there are no days off for a teacher: he or she is constantly occupied with thoughts about school, lessons and pupils. This is why it is often said that teacher’s job is very specific. On the one hand, a good teacher does not only give knowledge but also serves a model of behaviour for his or her pupils, especially the young ones. He or she forms the pupils’ attitude to the subject. The manner in which he or she teaches matters a lot. On the other hand, a teacher mustn’t forget that he or she must study from the pupils. Studying is a constant process for a teacher. If one stops studying, learning something new every day, both in the sphere of his or her professional interest and in people’s relations, this means that it is time to stop teaching. Otherwise, it will do no good for the teacher and the pupils. The teacher’s task is not only to provide the pupils with information, but also to prepare them for everyday life, to make them good and responsible citizens of the society. While communicating with children a teacher studies them. The teacher must know the pupils’ interests beyond the classroom, share their concerns, and leam about their needs and abilities. He or she must be well aware of the pupils’ good and bad sides, too. Classroom climate depends a lot on the relations between a teacher and a pupil. Mutual respect of the teacher and the pupils is necessary if one wants to create a good and fruitful atmosphere at the lesson. To achieve this, the teacher’s thinking should be on a higher level than that of the pupils. It is the main aim of education to help children to live in the community and to prepare for real life situations. School becomes a place for work and play, for living and learning. A teacher takes an active part in shaping a child’s character, fostering honesty, kindness, and cooperation. Teaching is a very difficult job but those who are well equipped for it will have a happy and interesting life.
