8个学生排队来使用体育道具A、B、C，轮到任何一个学生该学生连续使用体育道具ABC。
<font color=red>结论：体育课程40分钟，每个学生绝大部分时间(70%)是排队而不是在做体育运动；排队期间学生无聊而相互嘻哈闹着玩，老师还需要去维护秩序。

全部学生一起循环运动，每个学生都在同时运动，40分钟体育课程时间，基本上都是在运动着。

阵列同步活动，每个学生在体育课期间都是同步做运动，列队：①做操；②跳绳；③俯卧撑.....

***解决方法***
<font color=blue>组织学生体育活动的形式需要抓住要领：人每个学生在体育课的时间内70%+的时间在运动中，而不是在等候排队中度过。</font>

## 学生举手互动行为
* 举手发言互动的主动性和公平性
* 老师点名发言的被动性和偏向性
这两种方式交错使用均可以让学生集中注意力提升关注度。


***举手人数太多***
* 45人班级20人举手，时间限制最终仅5人发言
75%的人举手了但没有发言机会，这五位发言者也是被老师点名的，学生仍然是被动性和老师偏向性。
问题出在：老师问的问题引导性、思考性不够，就是太简单了，学生抢着举手！让主动性和公平性无法提现。

***举手人数太少***
* 45人班级5人断续举手4人发言
老师问的问题引导性、启发性、思考性较强，学生通过思考后才举手，五人断续举手，按先后顺序发言。
避免优等生总是抢占举手发言机会，老师引导学生举手表达不知道的问题，<font color = blue>学会提问题</font>本身就是很大的启发性和思考性。
