在平时的教学中,我们发现许多同学解题时常采用“就题解题”的策略,即解答一题丢一题.这样的学习不是一种好的学习数学的方法,解题时不能停留在问题的表面,一定要思考一下问题是否还有可探究的余地,新问题自己能解决吗?等等.这样解答一道题后就能获得丰富的收获.下面以两道数列 In normal teaching, we find that many students often adopt the strategy of “solving problems”, that is, solving one problem by one.This kind of learning is not a good way to learn mathematics and can not stay in The surface of the problem, we must think about whether there is room for exploration of the problem, the new problem can be solved? And so on .After you answer this question will be able to get rich harvest .In the following two series
