I try to do (to the best of my ability) a good job at a lot of subjects: all of the ones I teach, actually. I leave behind science and art, because I don't teach them, so I feel I don't need to perfect those yet. In all subjects I try to adopt an inquiry approach, and have students do rather than sit and listen. I don't always get it right, but I am constantly moving onward. French has always been that subject that I feel is not a very inquiry based course. You either know words or you don't. That is why I have really attached to the AIM program. I have friends who hate it, but I have loved it, and I feel it is the only way I can truly teach French.
If you are unaware of AIM, it basically teaches students French through gestures (similar to but not sign language), and therefore students stay in the target language (French, but it is also available for Spanish). I love this, because students are listening to and looking for patterns all the time that they are in French class. It takes a lot of effort, and energy, but I wouldn't have it any other way.
