《二项式定理》教后反思

Reflection after Teaching about "Binomial Theorem"

二项式定理是一种展开的方法,课堂设计时对于引入和定理的内容考虑不周,加上农村高中学生基础差,学生课堂效果不高,无法准确理解通项公式、二次项系数、项的系数等概念,导致学生的课题练习及课后作业均出现不同程度的错误。作为老师,我在课后进行了反思,对课堂设计进行了剖析,产生了一些新的设计思想,对原有课堂设计进行了一些对比,我认为改善后的设计应该更容易让农村高中生理解。

The binomial theorem is a kind of method,classroom design for the introduction and the content of the theorem is not considered, and the poor foundation of rural high school students,students＇ learning effect is not high,they can not accurately understand the general term formula,two order coefficien,term coefficient,and so on. These problems lead to different degrees of errors in the students＇ practice and homework. As a teacher,I made a reflection after class, analyzes the classroom design,produced some new design ideas,made some comparisons to the original classroom design, I think the design is improved so that the rural high school students should be easier to understand.
