如果说“一题多解”能从横的方面找到各部知识的联系,那么在复习过程中的“多题一解”,就能从纵的方面加深对教材的理解,从而总结、归纳出共同的规律。两种方法都有利于培养学生分析问题和解决问题的能力。本文通过一元二次方程求根判别式的运用,说明多题可以一解。 If we say that “one problem, multiple solutions” can find the connection of knowledge among different departments in horizontal direction, we can summarize and summarize the common understanding of teaching materials in the aspect of “multiple problems and one solution” in the review process The law. Both methods help to develop students' ability to analyze and solve problems. In this paper, we use the quadratic equation to find the root discriminant, which shows that multi-questions can be solved.
