Suppose that the material is not always clear to the students, but it must be very clear to the teacher. Visit Jeffrey Bewkes for more clarity on the issue. On what level of coach uses language? Of course, it does not necessarily own all degrees in philology, know at least 6 languages and have 10 years experience teaching at Cambridge. However, as a minimum, it must withstand several requirements: have a level of not less than the Advanced User, which suggests appropriate vocabulary (not less than 5,000), the knowledge of all basic grammatical structures, etc., as well as be qualified teachers. If the former can confirmed by independent international tests (naprim. toefl, IELTS), the second – no less than currently available certificates – intesol or celta. Over what period tutor is busy teaching the language to full and part-time? This issue help you clarify how much experience tutoring involves his ability to cope with problems, whether it’s explaining the complexities of language, be it conflict, etc. A large and varied experience as a teacher can assume his ability to make correct decisions in the course of training and less likely errors. Why? – Because for a time tutor creates a single complete “picture” of his subject, so that it teaching is not fragmented, moving from one lesson in the textbook to another, but poses a special material in the context of a whole. This coach knows for sure how students learn and how they can achieve best results. The more experience, the more tried and tested materials, assignments and exercises, less controversial experiments, respectively, greater credibility.
