风洞实验直播教学方法研究

Research on live broadcast teaching method for wind tunnel experiment

利用互联网、多维高清摄像、课堂管理设计,将地处较远的大型风洞内的实验过程以直播的方式带进教室,既可以通过计算机投射到屏幕上进行授课,也可以直接在学生自己的计算机上进行链接。在课堂上,教师可通过远程控制摄像系统展示实验细节,讲解实验过程。通过清华大学飞行器基础实验课堂的教学实践表明,这一方法能够取得良好的教学效果,能够提高稀缺、贵重实验平台的利用率和使用效果,可以推广到其他大型实验教学平台。

By using the internet,multidimensional high definition camera and classroom management design,the large-scale wind tunnel experiment is brought into the classroom through a live broadcast teaching method,which can be projected onto a screen by a computer and can also be linked directly to students＇ own computers.In the class,the teacher can show the details of the experiment by the remote-control camera system and explain the process of the experiment.The aerocraft basic experimental classroom teaching practice at Tsinghua University shows that this method can achieve good teaching effect,and improve the utilization ratio and effect of the scarce and valuable experimental platform,and it can also be extended to other large experimental teaching platforms.
