所谓“衔接”从字面意思上是指用某个物体连接两个分开的物体,把事物首尾连接。对于教学来说,就是将上一阶段的学习与下一阶段的学习结合在一起,这样不仅符合学生的认知规律,能减少学生的陌生感,而且对提高学生的学习效率也有很大帮助。所以,在素质教育思想的影响下,教师要做好初高中数学教学的衔接,以帮助学生更好地理解相关的数学理论知识。而“二次函数”则是初高中数学教学中的衔接点,这对高效数学课堂的实现也起着非常重要的作用。
The so-called “convergence ” literally means using an object to connect two separate objects, the end-to-end connection. For teaching, it is the last phase of learning and the next phase of learning together, so that not only meet the cognitive rules of students, can reduce the strangeness of students, but also to improve student learning efficiency is also very helpful. Therefore, under the influence of quality education thought, teachers should make the connection of mathematics teaching in junior and senior middle schools to help students better understand the relevant knowledge of mathematical theory. And “quadratic function ” is the connection point of maths teaching in junior high school, which also plays an important role in the realization of efficient math class.
