采用“先学后教、先试后导、以学定教、深入探究”的学习方式,让学生在教师精心创设的学习情境中,进行自主的探索、发现、思考、交流,亲历观察、实验、猜测、计算、推理、验证等活动过程,得到的不仅是数学知识,更主要的是数学学习的方法和数学的思想,从而激励学生进一步主动学习,产生我会学的成就感. Adopting the method of “learning first, teaching first, then learning to teach, exploring deeply” to let students explore, discover, think, exchange and witness their own experiences in the carefully created learning situations of teachers. , Experimenting, guessing, calculating, reasoning, verifying and so on. What we get is not only mathematical knowledge, but also mathematics learning method and mathematics thought, so as to inspire students to further study actively and produce the sense of accomplishment I will learn.
