I've observed that the weakest FTs focus on pronunciation in their classrooms.

I suspect this is because their students already understand English grammar better than the FT. A perusal of this board will give you a general idea of FT writing skills. And most FTs are in love with the sound of their own voice.

As unimportant as pronunciation is, the teaching of pronunciation requires an understanding of the physiology of sound creation and an intimate knowledge of IPA characters; both of these skills are not in the skillset of most FTs. Explaining sound creation physiology to students is best done in their native language. Discussing glottal stops with students in English is futile.

For the FT who has no idea about the meaning of the above:

Pronunciation is unimportant and you DO NOT know how to teach it.

Dance. Drone your PPTS.
