一轮复习期间,笔者所在学校组织了一次全员公开课,高三文科备课组确定的课题是《导数在函数中的应用》.围绕这一课题,组内教师进行多次讨论,甚至争论.1.立意之争所谓立意,这里是指一节课的主题.即通过一节课的学习,教师想让学生学到什么.Y:让学生掌握导数在函数中的应用的几种题型,包括单调性、极值和最值的求法、函数零点个数的判断、恒成立问题的转化等问题.S:导数知识点较多,导数在函数
During a round of review, the author’s school organized an open class for full-time students, and the subject set by the High School’s three-lesson preparation group was “Application of Derivatives in Functions.” Around this subject, the teachers in the group discussed many times and even argued.1 The conception of the so-called controversy The so-called conception, here is the theme of a lesson, that is, through a class of learning, teachers want students to learn what.Y: Let students master the derivative in the function of the application of several types of questions, including Monotonicity, extreme value and the most value of the method, the number of zero function judgment, constant problem of conversion and other issues.S: Derivative knowledge points, the derivative in the function
