現象一 不知道著急：動作拖拉
很多孩子平時寫作業的時候就喜歡拖，每次都要磨蹭到晚上8點半，甚至是9點以后才開始寫，上學尚是如此，假期就更加更加喜歡拖了。
經常會說明天再寫吧，等到了明天，又不想寫再推遲，直到開學前幾天，才開始夜以繼日的趕。
孩子的小心思：假期這么長，我先玩幾天再寫也來得及!大不了最后幾天多寫點。
現象二 人在心不在：注意力不集中
好不容易下定決心寫了，可是心思完全不在作業上，最多堅持15—20分鐘，然后就一會出去倒杯水，一會去上個廁所;家里來客人了，一定要出去看看，不然就放個手機在旁邊，拍個自拍發個朋友圈……完全沒有時間概念，能2個小時完成的作業，硬是被拖到了5個小時。
孩子的小心思：寫作業好無聊啊~好煩啊~我把這道題寫完，玩一會兒游戲，再寫吧。這樣才有動力。
現象三 質、量難兼顧：答題不走心
平時寫作業的時候，孩子不敢怠慢，因為寫不好第二天會被老師批評。可暑假不一樣啊，老師不會每天都盯著你作業質量，于是孩子答題非常不規范：不寫題號;數學應用題也不寫“解”，得出結論后也不寫“答”;格式混亂，解題過程跟草稿紙上的演算一樣龍飛鳳舞。
還有的孩子對橡皮或者涂改液有嚴重的依賴，稍微有一點點小瑕疵，就擦掉重寫，不僅效率低下，書面不整潔。
關于作業，一定要告訴孩子的話 作業每個人都有，并不是老師和家長故意針對你。所以，不要抱怨，不要覺得不公平，反正學得多學得少都是你自己的。不管怎么樣，你始終都要完成，每天按時完成了再放心地玩還是千方百計拖到最后，玩的時候還要惦記著作業，全憑你自己選擇。作業就是這樣，你難的時候別人也難，你簡單的時候別人也簡單，但不是每個人都可以做到思考全面，認真仔細的，差距就在這里。每一道你做過的題，只要認真思考了，都是你新的知識和經驗。就像人生一樣，經歷過的，就都是你獨一無二的財富!
