【教学分析】本节标题明确,说明了基本不等式的作用,从高考看,基本不等式是一个热点,它在不等式证明和求最值过程中有着广范的应用,是一个有效的工具。【三维目标】(1)知识目标:理解并掌握基本不等式a+b2≥姨ab(a>0,b>0),会用此不等式求某些函数的最值,能够解决一些简单的实际问题。(2)能力目标:通过类比,直觉,发散等探索性思维的培养,激发学生的学习兴趣,进一步培养学生的解题能力,创新能力和勇于
Teaching Analysis The title of this section is clear, indicating the role of basic inequalities, from the entrance examination, the basic inequality is a hot spot, it has a wide range of applications in the process of Inequality Proof and value, is an effective tool. 【3-D Objectives】 (1) Knowledge Objectives: To understand and master the basic inequalities a + b2 ≥ a ab (a> 0, b> 0), will use this inequality to find the most value of some functions and can solve some simple practical problems . (2) Objectives of Ability: To stimulate students ’interest in learning through the cultivation of exploratory thinking such as analogy, intuition and divergence so as to further develop students’ problem-solving ability, innovative ability and courage
