计算是小学数学教学的重要内容之一,是学生提高计算能力,思维能力的重要载体。不管是课改前还是课改后,教材对计算教学的基本内容和基本要求,并没有发生很大的变化,只是在编排体系上有所差异,这样的变化对教师的教学,学生的计算学习会产生什么样的影响?我们应该怎样把握教材才能做得更好?拟以人教版义务教育数学教科书和课程标准实验教科书的“除数是一、两位数除法”为例,作进一步的比较和分析。 Calculation is an important part of primary mathematics teaching. It is an important carrier for students to improve their computational ability and thinking ability. No matter before or after the course reform, the basic teaching contents and basic requirements of teaching materials have not changed a lot, but they have some differences in the arrangement system. Such changes affect the teaching of teachers and students’ computational learning What kind of impact will we have? How can we grasp the teaching materials to be better? To take the PEP mathematics textbook and curriculum standard experimental textbook “Divisor is one and two digit division” as an example, Comparison and analysis.
