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.

中關村外國語學校在線教學對教育**者來說是一種相對較新的教學方式。就在50年前，一個學校不需要混凝土建筑就可以運作的想法看起來是不可能的。當時，學生們應該坐在一個房間里，課桌后面，聽老師講課。然而，世界迅速發展，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.

物理學是幫助學生了解周圍世界及其**原理的學科之一。學習物理的一個關鍵方式是對事物的**方式有一個清晰的視覺圖像。學生學好物理的一個主要條件是能夠通過每個細節想象其物理現象。以氣壓為例，如何解釋?我們看不見空氣，但在進行了一些實驗之后，我們可以得出一個非常好的模型，它說空氣是由比子彈振動、旋轉和飛行速度更快的微小顆粒組成的。它們飛，旋轉，振動，所有這些都發生在同一時間!因此，當他們碰到某物時，他們會在某個區域施加力，從而產生壓力。現在，一旦我們對正在發生的事情有了清晰的圖像，就很容易解釋氣壓是多少。

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:

在學生頭腦中建立某種現象的詳細圖像，的方法是給他們看一張圖片、視頻或動畫。慶幸的是，我們今天非常幸運，因為互聯網上許多不同的教學資源可以用來支持科學課。在這里，我們想跟大家分享我們在物理課上經常使用的兩個主要資源：

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/一個在線平臺，能夠讓學生在課堂上或通過遠程學習獲得樂趣、參與度和影響力。在幾分鐘內創建有趣的學習游戲，或者從數百萬個現有游戲中選擇一個主題，復習和強化知識，并進行形成性評估。

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.

生物化學物理教學的選擇。PhET交互模擬項目創建免費的交互數學和科學模擬。PhET sims基于廣泛的教育研究，通過直觀的、類似游戲的環境吸引學生，學生通過探索和發現學習。

That is how 21st century quarantine mode classroom looks like .

這就是21世紀隔離模式下教室的樣子。
