2) I'm taking a French "practical phonetics" class this coming semester. This will be the first time in six years of learning French (one in middle school, four in high school, and one at the university-level) that I'll be taking such a class. Do you think the focus on phonemes and closely differentiating between vowel sounds and such would be useful to pass onto a beginner? Or would it be overkill as long as I concentrate on making sure I'm pronouncing everything correctly to her?
Thanks! Any other foreign-language-tutoring advice will be welcome as well :)
