1背景近期,笔者在区内开设了一节展示课,备课时对这节课的定位是一节九年级小综合性质的探究课,课题为“用函数观点看方程”。本节课的立意是用问题驱动学生探究函数与方程的关联,在教材的基础上适当提升高度,促进学生在数学学习上的发展。现将本节课的教学片断分析和课后思考整理出来,与同仁分享。2展示课分析2.1情境揭示主题,板书布控全局
1 Background Recently, I opened a showcase class in the district, and the orientation of this lesson during lesson preparation is a small comprehensive inquiry course of Grade 9 with the topic of “Equations from a Function Perspective”. The purpose of this lesson is to use question-driven students to explore the correlation between functions and equations, and to appropriately elevate the height of textbooks so as to promote students’ development in maths learning. Now this lesson teaching fragment analysis and after-class thinking out, and colleagues to share. 2 Showcase Analysis 2.1 Situation Reveal the theme, the overall distribution of plank control
