1教材内容分析二次函数历来是教学的重点,也是难点,更是考试的热点。本节课“二次函数在闭区间上的最值”安排在《数学1》(必修)第一章“1.3.1单调性与最大(小)值”一节教学之后,是研究函数抽象性的具体载体,从而可以使学生形象直观地理解函数的单调性、最大(小)值及其几何意义,并能深刻体会分类讨论思想和数形结合思想在解决数学问题中的重要作用。
A textbook content analysis Quadratic function has always been the focus of teaching, but also difficult, it is hot exam. This lesson “quadratic function in the closed interval of the most ” arranged in the “math 1” (compulsory) the first chapter “1.3.1 monotony and maximum (small) value ” section is taught, is It can make students understand the monotonicity, maximum (small) value of the function and its geometric meanings intuitively, and can profoundly understand the importance of the classified discussing thought and the mathematical form combining thought in solving the mathematical problems effect.
