排列组合是高中数学的重点和难点.如何解决排列组合中疑难问题,是高中数学教师所关注的重要内容.排列组合有着生涩难懂,种类多样,覆盖面广的特点.对于一些限制条件较多的问题,学生会产生困惑,因此,就要找到合适的方式来解决学生的困惑,这点是十分重要的.一、将排列组合中容易混淆的知识点进行系统性的梳理在高中数学排列组合学习过程中,有很多相似的知识点.这就要求学生能够正确认识问题,选出合适的方法来解题.下面举出一个比
Arrangement combination is the high school mathematics the key and difficult.How to solve the arrangement of the combination of difficult problems is a high school mathematics teachers are concerned about the important content.Arrangement combination has a jerky difficult to understand the variety and variety of coverage of a wide range of characteristics.For some restrictions Problems, students will be confused, therefore, we must find a suitable way to solve the confusion of students, it is very important.First, the arrangement of the combination of easy to confuse the knowledge points systematically sorted in the high school mathematics arranged combination of learning process , There are many similar knowledge points.This requires students to correctly understand the problem, select the appropriate method to solve the problem.
