孩子写作业的坏习惯
现象一 不知道着急：动作拖拉
很多孩子平时写作业的时候就喜欢拖，每次都要磨蹭到晚上8点半，甚至是9点以后才开始写，上学尚是如此，假期就更加更加喜欢拖了。
经常会说明天再写吧，等到了明天，又不想写再推迟，直到开学前几天，才开始夜以继日的赶。
孩子的小心思：假期这么长，我先玩几天再写也来得及!大不了最后几天多写点。
现象二 人在心不在：注意力不集中
好不容易下定决心写了，可是心思完全不在作业上，最多坚持15—20分钟，然后就一会出去倒杯水，一会去上个厕所;家里来客人了，一定要出去看看，不然就放个手机在旁边，拍个自拍发个朋友圈……完全没有时间概念，能2个小时完成的作业，硬是被拖到了5个小时。
孩子的小心思：写作业好无聊啊~好烦啊~我把这道题写完，玩一会儿游戏，再写吧。这样才有动力。
现象三 质、量难兼顾：答题不走心
平时写作业的时候，孩子不敢怠慢，因为写不好第二天会被老师批评。可暑假不一样啊，老师不会每天都盯着你作业质量，于是孩子答题非常不规范：不写题号;数学应用题也不写“解”，得出结论后也不写“答”;格式混乱，解题过程跟草稿纸上的演算一样龙飞凤舞。
还有的孩子对橡皮或者涂改液有严重的依赖，稍微有一点点小瑕疵，就擦掉重写，不仅效率低下，书面不整洁。
家长怎么教育孩子写作业
关于作业，一定要告诉孩子的话 作业每个人都有，并不是老师和家长故意针对你。所以，不要抱怨，不要觉得不公平，反正学得多学得少都是你自己的。
不管怎么样，你始终都要完成，每天按时完成了再放心地玩还是千方百计拖到最后，玩的时候还要惦记着作业，全凭你自己选择。
作业就是这样，你难的时候别人也难，你简单的时候别人也简单，但不是每个人都可以做到思考全面，认真仔细的，差距就在这里。
每一道你做过的题，只要认真思考了，都是你新的知识和经验。就像人生一样，经历过的，就都是你独一无二的财富!
