     Tom was one of the brightest boys in the year, with supportive parents. But when he was 15 he

suddenly stopped trying. He left school at 16 with only two scores for secondary school subjects.One

of the reasons that made it cool for him not to care was the power of his peer(同龄人) group.

      The lack of right male(男性的 )  role models  in  many of their lives-at home and particularly in the

school environment(环境) --means  that  their  peers  are  the  only

people they have to judge themselves against.

     They don't see men succeeding in society so it doesn't occur to  them that chey could make something of themselves. Without male teachers as a role model, the effect of peer actions and street culture (文化)

is all-powerful. Boys want to be part of a club. However, schools can provide the environment for change, and provide the right role models for them. Teachers need to be trained to stop thal but not in front of a

child's peers. You have to do it one to one, because that is when you see the real child.

      It's pointless sending a child home if he or she has done. wrong. They see it as a welcome day off to

watch television or play computer games. Instead, schools should have special unil where a child who has done wrong goes for the day and gets advice about his problems-somewhere he can work away from his peers and go home after the other children.
