Nobody argues that language knowledge is very important nowadays. It is not only reliable basis for better communication, but today it is also the source of technological progress as it enables rapid exchange of information and research of common global problems. The development of language skills aims at active expansion of students’ proficiency in English. Language classes at a higher school always make use of the texts of specific professional areas (architecture, business, civil engineering, electronics, environment, management, etc.). Such texts should usually be focused on the communicative needs of the students of a certain higher school. However, teaching/learning ESP includes much more than the teaching of English through specific material and content. Teaching ESP combines development of linguistic skills together with the acquisition of specific information. Even homework assignment should be associated both with the speciality and with the skills mentioned. Active participation in various interdisciplinary cooperative programmes on the international level requires academic knowledge, scientific competence and objective evaluation of new ideas. The knowledge of English facilitates the access to the resources of new information. Students and teachers are given opportunities to study or to teach for some period at the most prominent schools abroad. Teaching languages is aimed at raising the quality of language studies and of higher education as well. Two Types of English The division of the English language studies into two types requires careful scrutiny of the needs and interests of the learner. Traditionally a secondary school learner or even a college student does not think much of the way he is going to use his foreign language knowledge. He realizes he needs this subject as it is included in the general curriculum and may become an important component when entering a higher school. On the other hand, general language teaching covers the teaching of the fundamentals of grammar, of expression as well as of phonetics and provides a stronger or weaker basis for possible later language studies. In any case the language teacher both at a secondary and at a higher school is in charge of the correct use of the language by its learners. Teaching language for specific purposes is determined by different – professional/occupational, social and other – needs of the learner. Therefore English for specific purposes (ESP) includes specialized programmes which are designed to develop the communicative use of English in a specialized field of science, work or technology. To be able to speak on a professional subject is not enough to know general vocabulary. However, a great part of professional vocabulary consists of general words, which either have a shift of meaning or make a new unit, usually becoming a compound word or a combination of words. In the case of ESP language teaching/learning is purposeful, i.e. predetermined by the need of the student not only to get familiarized with both the language of science and technology, thus with the English language of the subject he studies but also with the subject itself.
