15 years teaching all levels of French including AP in high school.
I teach all classes strictly in French - even French I. Students quickly expect you to only speak French and think it is weird if you do have to make a rare statement in English (of in French Club). It is a lot easier to stick with the target language than going back and forth and ends up being much easier. The first day of school is great because the students in French I are surprised they can learn without hearing any English. French II is excited because they can understand you.
Recent past-president Arizona chapter of AATF.
