“指数函数图象及性质”的教学共分两个课时完成,这是第一课时。本节课主要学习了指数函数的概念,指数函数的图象及性质。在新课改理念的指导下回顾这节课,有以下反思:1.这节课是在学生系统地学习了指数概念、函数概念,基本掌握了函数性质的基础上进行学习的,具有初步的函数知识,这节课的每一个环节以我引导,以学生的自主探究为主来完成是符合学情的,也符合新课改的要求。2.设计“指数函数的图象及性质”“y=ax中a的取值范围如何”
“Exponential function image and nature ” teaching is completed in two hours, this is the first lesson. This lesson mainly introduces the concept of exponential function, the image and properties of exponential function. In the new curriculum reform under the guidance of the review of this lesson, the following reflection: 1. This lesson is a systematic study of students in the concept of the index, the concept of the function, the basic grasp of the basis of the nature of the function to learn, with a preliminary Function knowledge, every aspect of this lesson to guide me to students based on the independent inquiry to complete is consistent with the academic situation, but also meet the requirements of the new curriculum. 2.Design “Exponential function of the image and properties ” “y = ax in the range of a value ”
