How to improve listening skills for technical students

Communication competence includes four main activities: speaking, listening, reading, and writing. Listening is the most difficult skill for many of our students. But that of the time a person is engaged in communication, approximately 9% is devoted to writing, 16% to reading, 30% to speaking, and 45% to listening. That's why for non-linguistic universities the perfection and development of the speech learning procedure becomes actual especially when we use academic hours of student independent work (self-study) for this purpose.
