Children today find it difficult to concentrate or pay attention in schools. More often than not, it can be observed that children are easy to lose their attention in schools. Objectively, this phenomenon can be ascribed to that children need to face more attractive thing nowadays. Teaching in an interesting way and training children's abilities of concentration are the solution to this problem. Adults may lose control in the modern society, let alone children. First of all, some children are allowed to bring smart phones to schools. Obviously, these smart phones, though useful in various ways, disturb them during classes. Someone choose to download English applications for learning, while others are absorbed in internet games. A recent study, from the Department of Psychology at the Peking University, showed that 23% students had experiences that playing games during a whole class;45% students said they viewed website during classes and nearly 100% students confirmed that they checked messages in classes. In addition, sleeping very late make them do not have enough energy to keep awake in classes. Since this problem has emerged, we can solve it in two aspects. On the one hand, teachers should abandon traditional teaching styles that teachers output knowledge on one side. The interaction between teachers and students can make classes more attractive. On the other hand, concentration training is really effective.The  Renmin primary school from China has set a good example, by introducing meditation classes, aiming to improve student's self-discipline. Amy, a 5-grade student, said that she would not play her smart phone during class because she learned self-control is courage under another form from meditation classes. In conclusion, owing to young need face so much lure currently, it is hard for them to concentrate in schools as people from the past. Therefore, not merely teachers should utilize an appealing way to teach but also students need attention practices.
