从听课中发现,有部分教师让学生做口答练习时,仍采用“开火车”的方法。我认为这种课堂练习的方法不可取。其理由有三: 一是不利于调动学生思维的积极性。因为小学生具有较强的好奇心和争胜心,对于教师在课堂上提出的挑战性问题,他们都能积极思考、踊跃发言,以求得老师对自己的表扬为满足。但是,他们毕竟还是儿童,学习的自觉性还未养成,如果老师不给他们布置学习任务或布置的学习任务不太具体,他们便觉得没有什么任务需要完成。在采用“开火车”的方法做练习时,因回答问题的学生的范围预先受到限定,使相当一部分学生因感受到没有回答问题的任务,而不去积极动脑子思维,长此以往还会造成他们思维的惰性。二是不利于教师准确掌握来自学生的反馈信息。课堂练习的目的之一,就是了解学生掌握知识,运用知识的情况,以便教师根据收集到的反馈信息,改进 From the lectures found that some teachers let students do oral practice, still use the “open train” approach. I think this method of classroom practice is not desirable. There are three reasons: First, not conducive to mobilize the enthusiasm of students thinking. Because pupils have a strong sense of curiosity and victories, teachers can think actively and actively in response to the teacher's challenging questions in the classroom so as to satisfy the teacher's compliments. However, after all, they are still children. The consciousness of learning has not yet been developed. If the teachers do not give them specific tasks of learning or arranging learning tasks, they feel that no tasks need to be completed. In the “open train” approach to practice, the scope of the students to answer questions is limited in advance, so that a considerable part of the students feel the task of not answering questions, not to actively mind thinking, the long-term will cause them to think Inert. The second is not conducive to teachers accurately grasp the feedback from students. One of the purposes of classroom practice is to understand the situation of students' mastery of knowledge and use of knowledge, so that teachers can improve their feedback according to the information collected
