一、问题描述2016年12月,刘逸晴参加第八届东芝杯中国师范大学理科师范生教学技能创新大赛,课题为《曲边梯形的面积》.“求曲边梯形的面积”是人教A版高中数学选修2-2第一章《导数及其应用》第五节定积分概念的第一课时,它是定积分概念、思想方法的起始课,它的基本解决方法可以追溯到高中必修三所学的割圆术,此二者存在一定的内在联系.在进行教学设计时,我们将割圆术作为曲边梯形的面积的先行组织者,在此基础上借以类比的方
I. Description of the Problem In December 2016, Liu Yijing attended the 8th Toshiba Cup Normal University Science Teachers’ Skills Innovation Contest on the topic of “Area of Trapezoid Trapezoid”. A version of high school math elective 2-2 Chapter 1 “Derivatives and Applications” Section V of the first set of integral concepts, it is the concept of definite integral, the starting point of thought method, and its basic solution dates back to high school Compulsory three learning circumcision, there is a certain internal relationship between the two.In the teaching design, we will circumcision as the first trapezoid area of the organizer, on the basis of analogy
