新课程改革以来,小学数学计算课课堂教学普遍存在两种现象:一是认为计算是基础课,学生只要掌握具体的算法,能正确计算出得数就可以了,于是课堂上出现了讲练结合为主的教学;二是认为算法多多益善,即使学生不能说出多种算法,教师也要多方启发。这样的教学现象不是新课改所倡导的,应该引起我们的注意。《得数是9的加法和9减几》这课的教学,让我改变了以往怕学生不愿意计算、不会计算的教学心态。良好的教学效果 Since the reform of the new curriculum, there are two common phenomena in the classroom teaching of math class in primary schools. One is that computing is the basic class. As long as students grasp the specific algorithms, they can correctly calculate the number of students. So in class, The main teaching; the second is that the algorithm is much better, even if the students can not say a variety of algorithms, teachers should also be inspired by many. This teaching phenomenon is not advocated by the new curriculum reform and should attract our attention. “The number of addition is 9 and 9 by a few” teaching this lesson, let me change the previous fear of students are not willing to calculate, will not calculate the teaching mentality. Good teaching effect
