传统的小学计算教学常通过机械重复的“题海战术”对学生进行训练,在计算教学中,教师对于计算结果比较关注,而忽视了对于学生计算过程的辅导。在算法法则应用与概括上不注重方法,导致学生对于计算教学内容不感兴趣,难以实现自主学习。小学数学计算教学包含很多方面,其中算理、口算、估算、简算等都是小学数学计算教学的重点内容。当前小学数学计算教学效果不佳,与数学运算教学内容、算理的融入以及重点运算模块教学的训 Traditional primary school computing often trains students through mechanical repetition of “question sea tactics.” In computational teaching, teachers pay more attention to the calculation results and ignore the guidance for the calculation of students. Application and generalization of the algorithm do not pay attention to the method, resulting in the students are not interested in computing teaching content, it is difficult to achieve autonomous learning. Mathematics teaching in primary schools contains many aspects, including arithmetic, calculation, estimation, calculation and so on are the primary focus of mathematics teaching. The current primary school mathematics calculation teaching effect is not good, and mathematics teaching content, arithmetic and key operation module teaching training
