The principle of activity in foreign language teaching is of utmost importance since learning a foreign language should result in mastering the target language which is possible provided the pupil is an active participant in the process, ne is involved in language activities throughout the whole course of instruction.
In modern psychology activity is now generally considered to be a main characteristic of cognitive processes. Activity arises under certain conditions. According to the Sets Theory the learner should feel a need to learn the subject, and have necessary prerequisites created for the satisfaction of this need. The main sources of activity are motivation, desire, and interest.
Young people in ourcountry want to know foreign languages. To illustrate this we may refer to the entrance examinations of language departments of higher schools where the competition is great; to the growing number of people who wish to study at various foreign language courses; to the desire of parents to send their children to specialized schools, etc. I. F. Kornkov 2 gives the following data obtained by means of questionnaires among 3368 pupils of town and village schools. 81 per cent of the pupils want to study a foreign language. About 11 per cent of pupils name it their favourite subject. The greatest desire to study a foreign language is observed among pupils of the 5th form, i. е., beginners (93 per cent). In other forms there is a tendency to the loss of interest in language learning. This shows that there is something wrong in teaching this subject. The teachers fail to sustain and develop the desire to learn which pupils have when they start the course.
Practice and special observations prove that pupils' interest depends on their progress in language learning. If pupils make good progress in hearing, speaking, reading, and writing, they become interested in learning the foreign language.
In teaching a foreign language it is necessary to stimulate pupils' activity by involving them in the act of communication in the target language either in its oral (hearing, speaking) or written (reading, writing) form.
