深国交院长随堂听课｜Principal Mobsby joins an AS Chemistry class

为了了解一下现阶段学校网络授课情况，周四下午，我选择了加入Manoj老师的化学课堂。身处印度的Manoj老师应用Zoom视频，给学生们上了一堂生动的线上课程。由于太久没有接触过化学，我已经不太能记起一些化学概念了。

This Thursday afternoon, I wanted to experience some of the online learning that our students are experiencing, so I joined an AS Chemistry class from Mr Manoj, conducted live online from India to his class here in Shenzhen using Zoom video. It has been many years since I studied chemistry and so it was quite difficult to remember some of the concepts.

Manoj老师首先通过反复查看测试，确保我们都能通过网络正常沟通。为了不占用太多网络带宽，我们关掉了自己的麦克风和摄像头，只有在需要问问题时才会打开自己的麦克风。课堂上，Manoj老师使用的是提前准备好的OneNote课堂笔记本，方便学生在线查看，课后也可以得到一个副本。同时他也共享了他自己的屏幕，这样我们就可以看着他屏幕上所写的内容，听着他的讲解，更好地理解学习内容了。

Mr Manoj began by checking that we were all able to connect, see and hear what was happening. We muted our microphones and had our own video off to help with the internet speed, unmuting when we needed to ask questions. He was using his OneNote class notebook which he had prepared so the class could access it live and would have a copy after the lesson. He then shared his own screen so as he wrote on the screen we could follow as well as hearing him.

我们先学习了卤代烃。Manoj的讲解非常具体，然后通过问问题的形式帮助我们巩固知识，确保我们每个人都清楚了这一内容。Manoj进一步讲述了我们所学的这一物质在实际生活中的应用，如何利用物质的特性使它产生相应的用途，比如说运用到灭火器中。

We started by looking at Halothane. Mr Manoj’s explanations were quite detailed and he asked questions as we went along to check that we could all understand what was going on. It was also good that he knew about how what we were learning is used in real life relating how properties related to actual uses, such as with the fire extinguisher.

随后，我们讨论了氟利昂的使用，也探讨了它对于大气的危害。

Then we got onto CFCs and a discussion of how there is damage to the atmosphere.

幸运的是，Manoj老师没有问我任何问题。虽然对于化学我是挺感兴趣的，但难度还是不小，很多东西早已经忘记了。

Luckily, he didn’t ask me any questions because, although interesting, it was quite difficult for me and the chemistry was beyond what I could remember.

非常感谢Manoj老师和他生动的化学课！

Thank you Mr Manoj and AS.E Chemistry.
