比较法在数学教学中的运用——从“函数的极限”与“函数的连续性”谈起

A Talk on Maximum and Continuity of Function

在数学教学中,比较法具有特殊的功效和作用。在“函数的极限”与“函数的连续性”教学中,“正”与“反”的比较,可加强对概念的深刻理解,“是”与“非”的比较,可以提高自我纠错能力,“异”与“同”的比较,可以认请问题的本质。

In mathematic teaching, the contrastive teaching has special function. In the teaching of Maximum and Continuity of Function, comparing 'positive' with 'oppositive' can make the comprehension to concepts strengthened; comparing 'true' with 'false' can make the self-correcting abieity improved; comparing ' different' 'same' can make the nature of problems seen through to.
