高效课堂的构建既要传授知识,又要培养能力,而且两相比较,后者反而更加重要.其中,运算能力是中学数学能力的重要方面之一,是数学中诸多能力的基础.在课堂的教学过程中,我们常发现这样的现象:很多学生在学习的过程中只重视解题思路的分析,却不愿意动笔去认真地演算,导致到真正考试时,题题会做却题题做错.很多人将这种现象归咎为粗心大意,而事实上这就是运算能力 The construction of efficient classroom not only need to impart knowledge, but also to develop abilities, but the latter is more important than the latter.One of the most important aspects of mathematics ability is computing ability, which is the basis of many abilities in mathematics. In the process of teaching, we often find such phenomenon: many students only pay attention to the analysis of problem-solving ideas in the process of learning, but do not want to work hard to calculate them earnestly, resulting in the real exam, Many people attribute this phenomenon to carelessness, which in fact is computing power
