《新课标》指出:培养运算能力有助于寻求合理简洁的运算途径解决问题。运算能力并非一种单一的、孤立的数学能力,而是运算技能与逻辑思维等的有机整合,更是一种数学思维能力,在实施运算分析和解决问题的过程中,要力求做到善于分析运算条件、探究运算方向、选择运算方法、设计运算程序,优化运算过程和运算方法,让运算符合算理,更合理简洁。 “New Curriculum Standards” pointed out: training computing power helps to find a reasonable and concise way to solve the problem computing. Computational ability is not a single, isolated math ability, but the organic integration of computing skills and logical thinking, but also a mathematical thinking ability, in the implementation of operational analysis and problem solving, we must strive to be good at analysis Computing conditions, to explore the direction of computing, computing methods, design computing procedures, optimization of computing processes and computing methods, so that computing coincidence, more reasonable and concise.
