近日,连续听了几节计算课的教学,或因是有人听课的缘故,老师们都比较注重让学生交流自己的算法,在追问“你还有什么方法”后,涌出很多的方法,教师满意的表情尽显,进而,简单小结后,几乎无一例外地有一句“这么多的方法,你喜欢哪种方法就可以用哪种方法算”。其实,算法多样化的问题在课改初期已有很多的讨论,算法的优化在老师们的头脑中也有印迹,但是在此背景下,依然出现“你喜欢哪种方法就 Recently, I listened to a few sections of teaching courses continuously or because some people attended the lectures, the teachers all paid more attention to letting students exchange their own algorithms. After asking ”what are the other ways for you?“ , The teachers are satisfied with the expression of full, and then, after a brief summary, almost invariably have a ”so many ways you like which method can be used to count.“ In fact, the problem of diversification of algorithms has been discussed a lot in the initial stage of curriculum reform. The optimization of algorithms is also imprinted in the minds of teachers. However, under this background, there still appears ”Which method do you like
