用几何画板解决函数最值问题教学的探讨

The Teaching Discussion on Settling the Problem of Max. and Min. of Function by Means of Geometry Palette

利用几何画板,动态演示一类含参数函数的参数运动变化过程,使学生直观理解变化,降低题目本身的内在负荷,从而减轻学生学习时的认知负荷,促进对参数变化的深入了解。

Demonstrating dynamic the movement process of parameter of a type of function including parameter by means of geometry palette will not only make the students comprehend the variation directly, but also reduce the inner burden of questions and relieve the students＇ cognizing burden in their study time, and promote them to understand parameter deeply.
