As a parent, you must set rules and decide what consequences wll be enforced for breaking them.
First, require that your daughter tends to her responsibilities, such as homework, chores, etc., before she is allowed to spend time watching TV, or using the computer or the iPod.
Second, limit the TV, computer, and iPod use to no more than 2 hours a day. In her free time, your daughter should play outside/exercise to prevent weight/health problems. Also, she needs to interact with other children in order to develop interpersonal skills and emotional maturity.
Third, be consistent in enforcing the consequences! If a rule is broken, for example if a chore is not done as agreed, withdraw privileges (no iPod/computer for a week, etc.). You mentioned that your daughter did not get good grades last year. Perhaps, you could suspend her iPod/computer use until she brings her grades up. Whatever you decide, explain your decisions to your daughter in a loving way, so that she understands what's happening and what she should expect.
I have a son who will be starting 4th grade in August 2012. He likes to play games on his wii, the computer and watch television. I allow him so many minutes a day and then he knows we have to have 1 hr of reading and 1 hour of another subject like math, science or vocabulary.
When school is in session television and games are only on the weekends. Once you establish the rules and stand by them they will know that you mean business. Even during the summer we have conversations about what is expected of him in the next grade and what we need to do over the summer to make sure he can perform those expectations.
Punishing her by taking away the things she likes will only make her dislike study/homework time even more and rebel. Give her 30 minutes or so of free time to play before she begins her study time. Make sure that you keep to the schedule yourself, 10 year old girls can be very manipulative. Reward her when she goes to do her homework or study without moaning and whining. The reward can be 5 extra minutes of play time on another day. Also, make sure that her study/homework area is free of distractions. She should not be doing homework in front of the TV. Is there a quiet place that can become the designated study area.
Make sure that you praise her when she is meeting your expectations and give consequences when she is not meeting your expectations.
Try to be closer to your child and do some of her school work together,then reduce the time spent on watching tv and playing I pad or computer. Motivate her by giving rewards when she does it right.with this I feel will encourage her.

It is a controversial issue. Recent studies show that there is some positive effect in socialising children. Dr. Przybylski’s findings reiterate this point. He is careful to remind readers that “the small positive effects observed for low levels of regular electronic play do not support the position that games provide a universal solution to the challenges of development and modern life.”
