It doesn't matter if you are a new teacher or a veteran--if you are having problems with something there is nothing wrong with asking for assistance. Get another perspective.
The best place to get advice is from someone who has been there before. That can be someone with one semester of experience, or thirty years of experience. If you can't find someone in person, get a recommendation for a book, or read one of my tips (or email me).
Just don't let pride keep you from asking someone to help you out.
