The names of educational personal in Russian is for me somewhat confuse. Please make it clear for me. Let's see:
University: Chief of a Department. For example in a Faculty of Economics. Department of Statistics and Econometry. Name of the chief of Department? This Department teaches the subjects: Statistics I, Statistics II and Econometrics. Everyone with its own teacher. Which is their name?
Secondary School (from abt. 15 to 18 yrs): teachers of Physics, Grammar, History, etc. Which is their name?
Primary School (up to 15 yrs. approx.): which is the name of these teachers? Thanks.
