提起学生学习中粗心马虎的情况,真是不胜枚举:有的读题读错,写字写错别字;有的把加法做成减法,颠倒四则运算顺序;有的考试时只做前一面,忘记后一面;有的应用题只回答前一问,忘记回答后一问……对此,许多老师都倍感头疼。究其原因就是注意力不集中,这是产生学习马虎的直接原因。有的课堂上不注意听讲,眼睛瞅着老师,心里却想着别的事,老师讲的知识自然记不牢;有的不认真读完题,就急于动笔,也有的不等老师问完就抢答;有的做作业字 Mentioning careless carelessness in student learning, is too numerous to enumerate: Some read the wrong reading, writing typo; Some add addition subtraction, reversing the order of the four operations; Some exams only to do the front, forget the latter side ; Some application questions only answer the previous question, forget to answer the latter question ... ... In this regard, many teachers are feeling a headache. The reason is the lack of concentration, which is the direct cause of sloppy learning. Some do not pay attention to listening in the classroom, looking at the teacher’s eyes, but think of other things in my heart. The teacher’s knowledge of nature does not remember well. Some do not read the questions seriously, so they are eager to write, and some wait for the teacher to finish Answer; some do homework word
