中学数学因为其学科的特点,决定了学科教学的课堂基本基调。因此在人们的传统印象中,数学课始终是一门枯燥乏味的学科,学生学习积极性不高,虽然教师在课堂上讲得口若悬河,但是学生听得昏昏欲睡。新课改施行后,新的教学要求需要彻底改变这种有碍于数学发展的形式,使数学课堂也变得津津有味,使学生也有学习数学的激情,能感受到学习数学知识的乐趣,这是当前我们新课改之后数学教师的首要任务。但是这个任务从实际行动的角度来 Middle school mathematics because of the characteristics of its discipline, determines the basic tone of the classroom teaching. Therefore, people’s traditional impressions, math class is always a boring discipline, students learning enthusiasm is not high, although teachers are eloquent in the classroom, but students drowsy. After the implementation of the new curriculum reform, the new teaching requirements need to completely change the form that impedes the development of mathematics, so that mathematics classrooms also become relish, so that students also have the passion to learn mathematics and feel the joy of learning mathematics, which is At present, our primary task of mathematics teachers after the new curriculum reform. However, this task from the practical point of view
