Abstract Cultivate students' innovative thinking is the requirements of education advancing, and also the core task of the new curriculum. Creation of context, and inspire students to independent research, is an effective way to cultivate students' creative thinking. This paper through teaching instance,demostrates that inspire students' independent inquiry to cultivate the innovative thinking.
Key words independent inquiry; innovative thinking
课外,有一位学生问笔者:能否不查《三角函数表》或不用其它数学工具比较 43坝?3爸档拇笮。坑肽母鲋荡螅空庑┪侍馐峭角三角函数值大小比较的问题,很实用。但笔者翻遍迄今所有数学课本及教辅资料,惊讶地发现:至今均尚未指出同角三角函数值比较方法。于是,笔者启发、引导该学生自主探究?
先在[0,]内,求函数 = 和 = 图象交点的取值:
解此题,先应用同角三角函数值比较方法得出<(参见例2),然后才根据对数函数单调增加所需的条件而确定底数的值域:>1。
以上都是从未见过的创新,这在一般课堂里是难以完成的,这说明探究性教学可不拘时间、场所和形式进行,启发学生自主探究,能培养学生创新思维。
