Good punishments for bad grades and disrespectful child?

My child, Bethan, has been misbehaving ever since school started. She has mostly D's, and one F. I've seem her perform well in her academics before, and I firmly believe that she is just slacking off this year. Also, she has shown extreme disrespect towards me. For example, when I tell her to clean her room in a polite manner, she will curse at me and call me deragaotry names and slam the door in my face. Could this be puberty? When I was her age, I certainly never would have treated my mother like this. Also, she arrives home late, much after her curfew. When I confront her about it, she screams at me saying I'm retarded and the worst mother ever etc. (How am I a bad mother if I feed, clothe her, house her, and raise her?). She also castigated me for not getting her the iPhone 5s (my response was for her to get a job, since she is of legal age to work). I don't know how she ended up this way. My oldest daughter has always shown me respect. Are there any good punishments to discipline her? I love my daughter with all my heart, so please so suggestions such as whipping etc.

I'm thinking she is a teen depending on her age would affect the punishment but you can't really punish teens but i'm going to assume she can drive you can take her drivers license away from her and i mean literally take it away, once threatened to cut mine up i straightened out after that or you could make her pay rent and threaten to kick her out

This is not the nineteenth century, so you can lose the corporal punishment ideas. Have you considered talking? I believe that if a parent tells a kid to do something or not, there should be an explanation because then the kid will understand why and do it more willingly. Talk to her about the value of money, and how a clean room will help her keep her things organized. Maybe she just needs some time to herself. Don't be strict, because if parents are strict the children just pull away. If you are warm and understanding, they will come to you.

I would tear that but up and tell she will respect you or get it again.

Honestly the best discipline is FEAR followed by LOVE. When I was younger and did bad things my dad would hit me with a belt and show anger with his facial expressions and I would cry but after that my mother would comfort me and tell me they punish me because they love me and she would explain and then she would make me apologize to my father and then my father will hug me and forgive me and we would all watch a movie and drink hot chocolate. This made me a better person, and I highly highly recommend that parents continue with this type of discipline, as I feel it works the best especially when it's done correct…

If you look around at some kids today you can tell right away who was spoiled as a child and who was disciplined as a child. Don't be afraid to instill FEAR on your child but just make sure it is followed by LOVE after your child understands why you disciplined him/her
