人教A版高中数学必修一函数的表示法教学设计（1）
本节课选自《普通高中课程标准数学教科书-必修一》（人教A版）第三章《函数的概念与性质》，本节课是第2课时，本节课主要学习函数的三种表示方法及其简单应用，进一步加深对函数概念的理解。课本从引进函数概念开始就比较注重函数的不同表示方法：解析法，图象法，列表法．函数的不同表示方法能丰富对函数的认识，帮助理解抽象的函数概念．特别是在信息技术环境下，可以使函数在形与数两方面的结合得到更充分的表现，使学生通过函数的学习更好地体会数形结合这种重要的数学思想方法．因此，在研究函数时，要充分发挥图象的直观作用．课程目标 学科素养A.在实际情景中，会根据不同的需要选择恰当的方法（解析式法、图象法、列表法）表示函数；B.了解简单的分段函数，并能简单地应用；1.数学抽象：函数解析法及能由条件求函数的解析式；2.逻辑推理：求函数的解析式；

Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand，70% think space is worth exploring because we have benefited a lot from it，such as using satellites for communication and weather forecast. What’s more，with further space research，we may solve the population problem by moving to other planets one day. Also，space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space.
