每次考试结束后,学生总是抱怨:“数列题又没有做出来”“我做了这么多数列综合题,都没有用”“递推数列的一些求解策略,如特征方程根、不动点、构造新数列等方法都没有用上”“数列究竟怎样复习才能提高解题能力”“我们高三复习要不要教材”“我们的数学课就是统一教学案,根本不需要教材”“我认为只做题讲题,恐怕效果不会太好,最好还是弄懂课本中的有关问题,然后
At the end of each test, students always complained: ”Numbers have not been made yet.“ ”I have done so many columns, and I have not used “” to push some of the solution strategies, such as the characteristic equations. Roots, fixed points, constructing new sequences, etc. are not used in the “” sequence. How can we improve the ability to solve problems?“”“” Our third year review requires textbooks“ ”“ Our mathematics class is a unified teaching case. , do not need teaching materials ”" I think only do questions, I am afraid the effect will not be too good, it is best to understand the problems in the textbook, and then
