Is native accent a motivating factor in teaching English to middle eastern learners or would a moderate accent suit the learning process ?

Yes of course

I always urge my students to develop a good accent, if possible. This helps and makes a speech better to ear, and this also highly pleases speakers and motivates my students

Native accent wud have students geared up for more acquisition

Dear asker, it is only the white skin and green or blue eyes. shhhhh and enough. I am sorry but it is a scientific fact.

Using English is better for learners all the time as they will really learn.If their language is used , they may forget what they learn.

Dear Mr.Denis,

Thanking you for your answer and I believe a good accent for middle eastern learners could mean a moderate accent like an Asian one, an Indian accent for example compared to a high end pure English or an American / Aussie accent which is associated with speed and most probably tends to distort the system of relationships between letters and sounds in a language which we term as "Phonics". Of course though the former may be more apt for western learners an asian accent which is spoken slower, clearer and with more phonitical expressions could be easily absorbed by young middle eastern learners.

What are we trying to achieve? Speaking with a "native" accent to my mind is the icing on the cake but it is not the be all and end all. The fundamental issue here is have they been taught "correct" English? ie spoken with the correct pronunciation and grammatically right, if so, that is the requirement, a "refined" accent will come in time.
