例谈数学题的检验

Illustration on the Checking Computations of Mathematics Problems

学生在数学学习中会出现失误,学会运用数学知识从不同角度来进行检验可以培养学生的验算能力,提高学生数学素质,本文从几个方面谈谈自己综合的几种检验方法。

Faults often take place in students＇ mathematics learn-ing, however, using mathematical knowledge to check the faults from different angles can cultivate students＇ ability of checking computations and improve their mathematical quality. Several methods of checking computations summarized by the writer are discussed from several aspects in this paper.
