笔者在教授一元二次方程时,结合多年的教学经验,针对学生学习中的重点和难点,设计了相应的方法,既夯实了基础,又逐步深化了知识点,让学生最终牢固掌握了要点,为下一步的学习打下了良好的基础。下面是我的教学反思,希望与各位同仁分享,起到抛砖引玉的作用。一、理清体系,立足定义,让学生掌握基础,掌握重、难点其实,所有数学问题的解决,基点都在于对基础的认知理解和运用。本课要让学生认知三个问题:1、什么是一元二次的
In the course of teaching the unitary quadratic equation, the author combined many years of teaching experience and designed the corresponding methods for the key and difficult points in student learning. It not only solidified the foundation, but also gradually deepened the knowledge points, so that the students finally mastered the key points. It laid a good foundation for the next step. The following is my reflection on teaching. I hope to share it with my colleagues and play an important role in this. First, clarify the system, based on the definition, so that students master the basics, master the heavy and difficult facts, in fact, the solution to all mathematical problems, the basic point lies in the understanding of the basic understanding and use. This lesson requires students to recognize three questions: 1. What is a quadratic one?
