Certainly it's important to realize that the english text is a merely an approximation of the actual pronunciation, but this isn't really that different than any other language that uses the western alphabet. The same thing applies in French, Spanish, German, Italian, etc. The student will quickly learn that even though the letters look the same, each language has its own idiosyncratic way of vocalizing them. Any textbook or teacher that does not emphasize this is not a very good one.
