English teacher and native speaker

Between english teacher and native speaker is enough different.

         If I think English teacher with Native speaker has advantages and disadvantages of teaching process in my opinion.in english teacher is clear and it's delivery more attractive, easily understood and easier vocabullary.
 to a listener may pronuncation delivered less good, but easy understood by the listener.
And the methods used also different from the native speaker. native speaker may ues methodes that give more priority to proununcation.
        English teacher more clearly understood when to submit the material in the structure or grammar.
If for speaking or pronuncation language better teacher. Because of their everyday english , and than a native speaker will be very fluent in pronuncatiion and more clearly.
