计算方法既然存在着多样化,那么学生找出了自己的方法后,并认为哪种方法最适合自己,就应允许他使用。一种算法不是上完一节课就被搁置,对于自己找到的方法,学生有一种积极的情感,在解决问题时,学生喜欢用自己的算法,学生在解决问题过程中会不断地反思,发现原来的方法又不适合自己,对自己的方法进行改进,从而找到最好的方法,这本身就是一个发展能力的过程。让学 Since there is a diversity of calculation methods, students should be allowed to use after they have found out their own method and think which method is most suitable for themselves. An algorithm is not put on hold after a class is finished. Students have a positive feeling about the methods they find. Students like to use their own algorithms when solving problems. Students will constantly reflect on the problems and find out The original method is not suitable for themselves, to improve their own methods to find the best way, which in itself is a process of development capability.
