sounds to me like your new at this and probably not properly prepared. Go sit and spend time observing and talking to a veteran teacher who is a master at what they do, and learn from them. It takes time, there is no magic bullet, but the best advice i can give al regel achas is to find something positive about her and “run with it”. The best chinuch advice i can give you in general is “model the behavior you want the child to emulate”. It also seems like you are close in age or of similar age to the student in question ,and treat her more like a friend. you need to break that mindset in order to command respect in the classroom. THe place for advice though, is amongst your co workers who have been doing this (Successfully) for years, not here IMHO> although im happy to advise!!
