Modern changes in economic and social situation caused great changes in educational environment, lingo-didactic methods and approaches. Transformation of content, educational technologies, ways of assessment evoked modifications in interpersonal relations between teaching staff and students. These relations are developed in the frames of constructivism and collaborative pedagogy. Nowadays a teacher cannot be considered as a source of information.
