Their teachers, Panameños all, are perfectly bright, but somehow have learned their pronunciation in an Español-ish manner. Even the teachers can not believe the number of adaptive/exceptional pronunciations in English. The pronunciation of common words such as 'woman' drives them a little nuts. I'm using the sentence, "The woman never reads a book." as an exemplar. This helps somewhat, but, brother, for a full course, the number of exemplars would be utterly enormous.
