“情·景·型”模式在机械波传播教学中的应用

On the Application of the“Situation-view-pattern”Mode to the Teaching of Mechanical Wave Transmission

在进行机械波传播一节的教学时,学生对传波物质不"迁移"和机械波呈现"周期性"理解不透彻。在具体的教学过程中,通过营造简单的"情"与"景",构建雏"型",引导分析"情"与"景",发展定"型",拓宽"情"与"景",引伸成"型",从而使学生建构起机械波传播的情、景和型,对机械波的传播不再感到"玄乎",对传波"物质不迁移"和机械波呈现"周期性"也运用自如。

In the teaching of mechanical wave transmission, student can not have a full understanding of＂non-migration＂of wave-transmitting materials and ＂periodicity＂ unfolded by mechanical wave. In the specific process of teaching, by means of the ＂situation-view- pattern＂ mode, students will no longer feel ＂enigmatic＂, and can have a perfect command of＂periodicity＂ unfolded by mechanical wave.
