冠状病毒情形下物理教学模式——北京市中关村外国语学校

　　Online teaching is relatively new approach for educators. Just 50 years ago an idea that the school can operate without having a concrete building looked impossible. Back then, students were supposed to be in one room seating behind the desks and listening to the teacher. However, world is developing rapidly discovering new ways to educate people.

　　在线教学对教育工作者来说是一种相对较新的教学方式。就在50年前，一个学校不需要混凝土建筑就可以运作的想法看起来是不可能的。当时，学生们应该坐在一个房间里，课桌后面，听老师讲课。然而，世界迅速发展，新的教育方式也在孵化。

　　Physics is one of those subjects that helps students to understand the world around and how does it work. One of the key aspects of learning physics is to have a clear visual picture of the way things work. One of the main condition for a student to be successful in learning Physics is to be able to imagine a physical phenomenon in every detail. Take an air pressure for instance, how to explain that? We cannot see the air, but after conducting a few experiments, we can come up with a very good model that says that air is made of tiny particles that vibrate, rotate and fly around faster than bullets. They fly, rotate, vibrate and all of that happens in the same time! Consequently, when they bump into something they exert force on a certain area, therefore creating pressure. Now, once we have a clear image of what is going on, it’s easy to explain what the air pressure is.

　　物理学是帮助学生了解周围世界及其工作原理的学科之一。学习物理的一个关键方式是对事物的工作方式有一个清晰的视觉图像。学生学好物理的一个主要条件是能够通过每个细节想象其物理现象。以气压为例，如何解释？我们看不见空气，但在进行了一些实验之后，我们可以得出一个非常好的模型，它说空气是由比子弹振动、旋转和飞行速度更快的微小颗粒组成的。它们飞，旋转，振动，所有这些都发生在同一时间！因此，当他们碰到某物时，他们会在某个区域施加力，从而产生压力。现在，一旦我们对正在发生的事情有了清晰的图像，就很容易解释气压是多少。

　　The best way to built up a detailed image of a phenomenon in student’s mind is to show them a picture, video or animation. Fortunately, we are very lucky today because there are many different teaching resources on the internet that can be used in a science class. Here we would like to tell you about 2 main resources that we use in Physics classes:

　　在学生头脑中建立某种现象的详细图像，最好的方法是给他们看一张图片、视频或动画。庆幸的是，我们今天非常幸运，因为互联网上许多不同的教学资源可以用来支持科学课。在这里，我们想跟大家分享我们在物理课上经常使用的两个主要资源：

　　https://kahoot.com/  An online platform that make learning fun, engaging and impactful for all students, in the classroom or through distance learning.  Create fun learning games in minutes, or choose from millions of existing games to introduce a topic, review and reinforce knowledge, and run formative assessment.

　　https://kahoot.com/一个在线平台，能够让学生在课堂上或通过远程学习获得乐趣、参与度和影响力。在几分钟内创建有趣的学习游戏，或者从数百万个现有游戏中选择一个主题，复习和强化知识，并进行形成性评估。

　　https://phet.colorado.edu/ The best one for teaching Physics, Chemistry of Biology. The PhET Interactive Simulations project creates free interactive math and science simulations. PhET sims are based on extensive education research and engage students through an intuitive, game-like environment where students learn through exploration and discovery. 

　　https://phet.colorado.edu/生物化学物理教学的最佳选择。北京市中关村外国语学校PhET交互模拟项目创建免费的交互数学和科学模拟。PhET sims基于广泛的教育研究，通过直观的、类似游戏的环境吸引学生，学生通过探索和发现学习。

　　That is how 21stcentury quarantine mode classroom looks like .

　　这就是21世纪隔离模式下教室的样子。
