代入消元法解二元一次方程组——教学设计与反思

Substituting Elimination Method to Solve Binary Linear Equations—Instructional Design and Reflection

摘要: 教师在教学中，让学生亲身体验知识是如何形成的，教师要着重注意思想方法的引导，让学生知道二元一次方程组如何向一元一次方程转化。本文的教学流程是“分析–概括–归纳–总结”，注重在学生已经具有的知识能力上，设置一些小的问题串，有助于学生寻找到解决问题的思路和办法。最后通过反思，使我对整个教学环节有了进一步深入的看法。

Abstract: In teaching, teachers let students experience how knowledge is formed. Teachers should pay attention to the guidance of thinking methods, so that students know how to convert binary linear equations to single linear equations. The teaching process of this paper is “Analysis-Summary” “Induction-Summary”, focusing on the knowledge and ability that students already have, setting up some small problem strings, which will help students find ideas and methods to solve problems. Finally, through reflection, I have a further indepth understanding of the entire teaching process.
