一、开发背景利用羽毛球筒的封盖作为标志物(点)或者球托已经被大家所熟知,但是单单一个封盖,重量偏轻,容易受到外力影响而改变位置。在室外课的教学过程中,更是如此。笔者在一次公开课上,由于封盖的分量太轻,预先设置好标志点被风横着刮偏了位置,令人手忙脚乱。因此,为了能够更好地利用封盖,笔者进行了简单的小改造,在不影响简便性的基础上增加了重量,提高了稳定性,让器具更具实用性。 First, the development background The use of the badminton cover as a marker (point) or ball holder has been well known, but a single cover, light weight, easily affected by external forces to change the position. In outdoor teaching process, even more so. The author in an open class, due to the cover of the component is too light, pre-set a good sign of the wind side by side scraping the position, it is confusing. Therefore, in order to make better use of the cap, the author made a simple and small modification to increase the weight and stability without affecting the convenience and make the appliance more practical.
