To ensure maximum understanding on the part of students about what is happening in the classroom, the teacher should speak clearly, not fast (but not too slowly), use a lot of international words similar to the corresponding lexical units in Russian, and support their speech with visual aids (pictures, objects, gestures, facial expressions, and voice, whenever possible). If students do not understand something, do not hurry to give up at once, and translate the incomprehensible text into Russian. Try to depict or express incomprehensible content some other way.
