数列作为高中数学的重点内容,常与函数、方程、不等式及导数等代数主干知识相融合,成为高考能力考查的把关题.近几年高考数列试题的设计上频频指向构造法,引来极大的关注,但从江苏高考近三年的得分情况来看,凡是涉及利用构造法求解的数列试题,得分率都几乎为零.究其原因,一方面与不少教师对构造法存有偏见有关,认为构造法较为灵活,不易通过训练后掌握;另一方
As the key content of high school mathematics, the sequence is often merged with algebraic backbone knowledge such as functions, equations, inequalities and derivatives and becomes the examination of the ability of college entrance examination.Recently, Of the attention, but from the college entrance examination in Jiangsu nearly three years of scoring conditions, all involved in the use of tectonic method to solve the series of questions, the scoring rate is almost zero.The reason, on the one hand and many teachers prejudice the construction method , That the construction method is more flexible, difficult to grasp after training; the other side
