摘要
极限、导数(微商)和定积分是微积分的核心概念.指出了微积分核心概念教学需达到的3个理解目标,从极限思想、算式构造和数学符号3方面分析教学难点并给出了相应的教学突破策略,即从辩证法角度澄清极限思想中无限逼近的意义,在归纳整体过程的基础上构造算式,解构名称记号以强化记忆.通过相关教学改革,学生回答问题的积极性和正确率都有明显的提高,相关教学难点问题得到了解决.
Limit,derivative(micro quotient)and definite integral are the core concepts of calculus.Points out three understanding goals to be achieved in the teaching of the core concepts of calculus,analyzes the difficulties in teaching from the three aspects of limit thought,formula construction and mathematical symbols,and gives the corresponding teaching breakthrough strategies such as clarifying the significance of infinite approximation in limit thought from the perspective of dialectics,constructing formula on the basis of summarizing the whole process,deconstruction of the name mark to strengthen memory.Through the relevant teaching reform,the students′enthusiasm and accuracy of answering questions have been significantly improved,and the relevant teaching difficulties have been solved.
