课堂导入多样性的探讨——以“流体压强与流速的关系”为例

Discussion on the Multiformity of Classroom Leading-in——Taking the Relationship between Pressure Intensity and Flow Velocity of Fluidfor Example

课堂导入是一节课的引子和开始的必要环节,其形式具有多样性.针对流体压强与流速的关系这节内容列举5种导入形式,并分别进行导入技能运用的4个环节示例,以供参考.

Classroom leading-in is essential for a lesson introduction and began,the form has diversity.Five leading-in forms are listed for this section of ＂the relationship between the fluid intensity of pressure and flow velocity＂,and proceed respectively to make four stages of the sample leading-in import skills using for your reference.
