新课程改革,不仅对数学课本知识进行了大的改动,知识难度也增加了,内容并不比以前少,而数学课时却减少了,很多数学教师为了完成教学任务开始在课外去抢时间,尤其在农村学校,学生素质差些,这种现象更为严重。这无疑是加重了学生的学习负担。要想改变这一局面唯有提高课堂教学的有效性。具体表现在:认知上,从不懂到懂,从少知到多知,从不会到会;情感上,从不感兴趣到感兴趣,从不喜欢到喜欢,从不热爱到热爱。那么如何提高课堂的有效性,通过一些学习与实践,在此我认 The new curriculum reform not only makes great changes to the knowledge of mathematics textbooks, but also increases the difficulty of knowledge. The content is not less than before, but the mathematics lesson time is reduced. Many mathematics teachers began to rush out of class after class to finish their teaching tasks, especially in Rural schools, poor quality of students, this phenomenon is even more serious. This undoubtedly aggravates the student’s learning burden. To change this situation only improve the effectiveness of classroom teaching.
