从函数图像中获取信息并解决有关问题,既是中考的热点,也是学生的易错点。复习阶段,需要安排一课时,进一步丰富学生对图像的认识,提高从图像中获取信息的能力。1学情分析(1)从知识储备来看,学生在之前的学习中,已系统学习了函数图像、一次函数、方程的应用等内容,并能够运用相关知识解决问题。但在从函数中获取
Obtaining information from function images and solving related problems is not only the hot spot of the senior high school entrance examination, but also the student’s easy point. During the review phase, one lesson needs to be arranged to further enrich students’ understanding of images and improve their ability to obtain information from images. (1) From the perspective of knowledge reserve, students have systematically studied the function images, the first-order functions, the application of equations and so on, and can apply relevant knowledge to solve the problem. But from the function
