| What is her body language like when she is doing this. Hair up all down her back, just at the neck, not at all? Does she stiffen before she lunges? How long has she been doing this?
Answering these question will help make the answer more specific but at the end of the day she is to be corrected harshly for breaking her sit or heal what ever and rewarded when she behaves correctly. She just has to learn that she cannot do this behavior without there being consiquences.
I would start the dogs moving past her at a gret distance where you know she will not break her position and reward her (treats, praise the lot) everytime the dog passes. The slowly move the dog closer and closer. With each successful pass she gets rewarded. If she breaks at all she is corrected for it.
Teaching a command to watch you will also help. Teaching her to displace her behavior onto you will help her have successful passes.
If you do these exercises correctly and do only small bits at a time then she should learn to behave very quickly. As you are already in class and have some control over her it should not be too difficult.
Do you use a release command? If not I would implement one so that she knows not to break a command until told otherwise.
