2022年二次函数复习课教学反思 .pdf

学习必备欢迎下载二次函数复习课教学反思立足于二次函数在初中数学函数教学中的地位，根据学生对二次函数的学习及掌握的情况，从梳理知识点出发采用以习题带知识点的形式，我精心准备了二次函数的第一节复习课，教学重点为二次函数的图象性质及应用。最初，“抛物线的开口方向、对称轴、顶点坐标、增减性”这一相关性质复习设计中安排了3 个训练题目，其中第（2）小题侧重在抛物线的对称性与增减性，集体备课后我在复习侧重方向上作了调整：加强利用配方法将二次函数一般式化顶点式、判断抛物线对称轴、借图象分析函数增减性等的训练，另外还预想借图象识别2a 与 b 的关系将是本节课的一个难点。本节通过建立函数体系回忆了二次函数的定义，其图象与性质及与一次、反比例函数图象的综合应用，相继进行，但此环节中“2a 与 b 的关系”学生没有提到，迫于突破此难点，我让学生观察课例图象，并进一步引导观察对称轴的具体位置后，仅有十几个学生准确理解、掌握，于是我进一步的分析“2a 与 b 的关系”由对称轴的具体位置决定，并说明由a0 与 b0 能推导出2a+b0 的方法仅适于此题，但效果不尽人意，仍有一部分学生应用此法解决相关问题。如此导致处理二、2、（2）题时间紧张，使得重点不凸现。将第（3）题留为课后作业，来了个将错就错，为下一节课复习“二次函数与二元一次方程”的关系巧作铺垫。通过本节课的备课与教学，我受益匪浅，感受颇多：学习必备欢迎下载1.每一个学生都有一定的知识体验和生活积累,每个学生都会有各自的思维方式和解决问题的策略.这一堂课我让学生成为数学学习的主人,自己充当数学学习的组织者,取得了意想不到的效果,学生不但能用一般式,顶点式解决问题,还能深层挖掘，巧妙地用两根式解决问题,可见学生的潜力无穷.2.本课遵循尊重学生，相信学生，依学生的“主体”教学思想，运用助思，助学，助练的启发式教学方法，启动了师生交流的“匣门”，使教学过程真正成为了师生间的双向活动3、在如何备复习课，准确把握一个单元及一节课的重点及突破难点方面有了很大提高；在巧妙驾驭课堂方面有了很大进步；在如何与他人相处方面有了更好的认识，踏踏实实地做人。总之，在实践中获得灵感，在交流中撞出智慧，在反思中调整思路，在坚持中取得进步。文档编码:CI10D5P10C5J2
