She clearly does not like school. It is best to talk to the teachers and ask them to give her small responsibilities and chores to do in school. If they give her positive attention when she performs these activities she will feel productive. Gradually she may be asked to do some activities with other children and thus increase her involvement with her fellow students. At home make it a point to discuss school with a lot of interest, and her actions during school. There are so many things to talk about: her studies, friends, teachers, school, classroom, some parents, lunchtime, sports, games, pe classes, music, craft, bands, etc. Once you and your wife show interest in her activities at school, she will feel good and want to impress you over a period of time. Sometimes you may have to feign ignorance with certain topics and subjects, as though she knows more than you. Invite some of her friends over for tea or a party; alternatively you can go with her to meet some of her school friends even if you have to travel a good distance. Never let her be alone at least at home and definitely with some support from her teachers this can be implemented even in school. Over a period of time she will respond to these suggestions positively and your problems will all be over and so will hers.
