计算能力是学生重要的数学能力,它直接影响到其他内容的学习,抓好了计算教学,学生的思维能力、心理品质和学习习惯等都将得到良好的发展。可以说,没有计算,也就没有真正意义上的数学学习。在深入学校调研时,有许多一线教师反映,新教材关于计算教学的编排虽然注重了数学情境化和生活化,在一定程度上激发了学生的计算兴趣,然而学生的计算能力却下降了,具体表现在计算的正确率下降,口算速度减慢并且学生分化情况提 Computational ability is an important mathematical ability of students, it directly affects the learning of other content, grasp the teaching of calculation, students’ thinking ability, psychological quality and learning habits will be well developed. It can be said that there is no calculation, there is no real sense of mathematics learning. During in-depth school investigation, many front-line teachers reported that although the compilation of computational teaching in the new textbook focused on mathematical contextualization and living, which stimulated students’ computational interest to a certain extent, the computational ability of students decreased but the specific Performance in the calculation of the correct rate of decline, slow down the mouth count and student differentiation mentioned
