不少同学平时在数学解题中不明算理、机械套用运算公式,不顾运算目标,盲目地进行推理演算,运算过程中缺乏选择合理、简捷的运算途径的意识,运算过程繁琐,错误率高,误以为是“马虎”、“粗心”造成运算错误,平时解题认为“只要方法对,做错了不要紧”。以上问题的根本原因是对运算能力的内涵缺乏科学认识。 Many students usually do not know how to solve problems in mathematics. Mechanical formulas are used in calculation. Regardless of computing objectives, they make inferences and calculations blindly. In the process of calculation, they lack the sense of choosing reasonable and simple calculation methods, and the calculation process is complicated and the error rate is high. Mistakenly thought it was “sloppy ”, “careless ” caused the operation error, usually solve the problem that “as long as the method is right, it does not matter wrongdoing ”. The root cause of the above problem is the lack of scientific understanding of the connotation of computing power.
