一元二次方程教学一直以来都是初中数学教学的重点和难点,也是中考的考点之一,它比学生学习的一元一次方程和二元一次方程的难度更大。因此,教师在教学时需要花费更多的时间来讲解相关的知识,然而在目前的教学中,教师的教学方法没有根据教学难度的提高,而做出适当的调整,导致学生在学习这部分知识时,始终无法达到预期的教学效果。结合多年的教学实践,简要地分析提高教学效率的方法。
The teaching of quadratic equation has always been the focus and difficulty of junior high school mathematics teaching. It is also one of the test centers for senior high school entrance examination. It is more difficult than the students to learn the first order equation and the second order equation. Therefore, teachers need more time to explain relevant knowledge in teaching. However, in the current teaching, teachers’ teaching methods are not adjusted according to the difficulty of teaching, and make students adjust to this part of knowledge When, always can not achieve the desired teaching effect. Combined with years of teaching practice, a brief analysis of ways to improve teaching efficiency.
