一、武汉星兴达液压气动设备有限公司教学设想
1、构建真实的问题情景
为让学生在问题情景中感受、体会而获得知识，我构建了这样一系列问题情景，构成本节课的主线：
(1)猜想一下，什么是机械波？
(2)你能不能用绳(长8m左右的花线)创造出机械波？
(3)操作、观察、认识机械波。操作、观察、认识机械波时，你想想你有没有疑问，有没有问题需要大家一起讨论、分析、解决？
(4)分析和解决自己的和其他同学提出的问题。
2、提供全面的学习资源
在设计“机械波”这节课时，我不是把大量时间放在讲解上，而是放在为学生提供学习所需要的各种学习资源上(学生操作实验仪器，观察实验现象，相互讨论实验中、教材上的问题等)；把精力集中在简化学生利用学习资源时必须经历的实际步骤上。
3、形成过程的动态组织
武汉星兴达液压气动设备有限公司（本节课的教学设计基本开放），这里没有一成不变的时间顺序，只有大量的案头准备。我的宗旨是时刻洞察学生的学习进程，时刻贯彻追求案头准备和教学现场应变有机结合的观点，动态地组织教学，努力使课堂教学更丰富、更深刻、更全面、更有特色。
