在中学数学中,特别是在高中数学中,知识上更具学术性、抽象性,解决起来常常需要充分发挥联想和创新的精神,在多年的高中数学教学实践中,笔者发现,有一类题型,在一定程度上,解决它们所运用的方法其实就是高中与初中数学的知识衔接点,即要联想到二次函数、一元二次方程的相关知识
In middle school mathematics, especially in high school mathematics, the knowledge is more academic, abstract, often need to solve the problem of giving full play to the spirit of association and innovation, in many years of high school mathematics teaching practice, I found that there is a problem type , To a certain extent, the method they are used to solve is in fact the connection point of knowledge between high school and junior high school mathematics, that is, the related knowledge of quadratic function and quadratic equation
