培养学生的计算能力是小学数学计算教学的一个重要任务,虽然计算器、计算机等工具的产生代替了人脑进行复杂的计算,然而就像日益发达的交通工具代替不了步行一样,基本的计算能力对任何人来说都是重要的。而且,计算教学对于提高学生数学学习能力、训练学生数学思维能力等都有着不可忽视的作用。新课程标准赋予了计算教学新的内涵,强调理解算理,注重在自主探究的基础上感悟算法,这样的改变给计算课教学带来巨大的冲击,然而,在“守旧”与“创新”的博弈中有很多 Developing students’ computing abilities is an important task in elementary mathematics teaching. Although calculators, computers and other tools are produced instead of the human brain for complicated calculations, just as the increasingly developed means of transport can not replace walking, the basic computing power It is important for anyone. Moreover, computational teaching plays an important role in improving students ’ability of math learning and training of students’ mathematical thinking skills. The new curriculum standard gives new meaning to computing teaching, emphasizes comprehension of arithmetic, pays attention to comprehension algorithm based on self-exploration, and such change has a tremendous impact on computing teaching. However, in “conservative” and “ Innovation ”in the game there are many
