运算能力指对记忆能力、计算能力、观察能力、理解能力、联想能力、表述能力及逻辑思维能力等数学能力的统称。目前,高中生运算能力较差,不少高中老师埋怨:“学生的计算能力太差了,连简单的运算都不过关,甚至连数学基础好的学生也经常出错”。这种状况出现的原因是多方面的。有的学生不对简单的公式、公理、定理进行记忆、理解,不明算理,机械地照搬公式,不能进行灵活运用;有的学生不注意观察,不进行联想,不进行比较,不顾及运算结果,盲目推演,缺乏合理选
Computing ability refers to the memory ability, computing power, observation ability, comprehension, associative ability, the ability to express and logical thinking ability and other mathematical capabilities collectively. At present, high school students have poor computing abilities. Many high school teachers complain: “The students’ computing power is so poor that they can not even pass simple calculations, and even students with good maths often make mistakes.” This situation occurs for many reasons. Some students do not make flexible use of simple formulas, axioms and theorems in memory, comprehension, and unknown reasoning. They can not mechanically apply formulas. Some students do not pay attention to observation, do not associate with each other, and do not make comparisons. Regardless of the results of operations, Blind deduction, the lack of a reasonable election
