新课改也给我们的数学课堂带来了巨大的变化:它使数学变得既贴近生活又关注学生的发展;它以实现学生的发展为宗旨,为他们提供了观察、猜想、思考、操作、验证、自主探索与合作交流的机会;它使得课堂教学由老师讲变为学生自主学习、互相讨论、互相交流、教师点拨、巩固练习等课堂活动。然而,在这种情况下,又产生一些新的问题,要我们去思考和解决。 The New Curriculum Reform has also brought about a tremendous change in our mathematics class: it has made mathematics both life-oriented and student-centered; it aims to achieve the development of students and provides them with observations, conjectures, thoughts, and actions , Verification, self-exploration and cooperation and exchange opportunities; it makes the classroom teaching from the teacher to student self-learning, mutual discussion, mutual exchange, teachers call, consolidation exercises and other classroom activities. However, under these circumstances, some new problems have arisen, which require us to think and solve.
