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.

　　在線(xiàn)教學(xué)對(duì)教育工作者來(lái)說(shuō)是一種相對(duì)較新的教學(xué)方式。就在50年前，一個(gè)學(xué)校不需要混凝土建筑就可以運(yùn)作的想法看起來(lái)是不可能的。當(dāng)時(shí)，學(xué)生們應(yīng)該坐在一個(gè)房間里，課桌后面，聽(tīng)老師講課。然而，世界迅速發(fā)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(xué)是幫助學(xué)生了解周?chē)澜缂捌涔ぷ髟淼膶W(xué)科之一。學(xué)習(xí)物理的一個(gè)關(guān)鍵方式是對(duì)事物的工作方式有一個(gè)清晰的視覺(jué)圖像。學(xué)生學(xué)好物理的一個(gè)主要條件是能夠通過(guò)每個(gè)細(xì)節(jié)想象其物理現(xiàn)象。以氣壓為例，如何解釋?zhuān)课覀兛床灰?jiàn)空氣，但在進(jìn)行了一些實(shí)驗(yàn)之后，我們可以得出一個(gè)非常好的模型，它說(shuō)空氣是由比子彈振動(dòng)、旋轉(zhuǎn)和飛行速度更快的微小顆粒組成的。它們飛，旋轉(zhuǎn)，振動(dòng)，所有這些都發(fā)生在同一時(shí)間！因此，當(dāng)他們碰到某物時(shí)，他們會(huì)在某個(gè)區(qū)域施加力，從而產(chǎn)生壓力。現(xiàn)在，一旦我們對(duì)正在發(fā)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(xué)生頭腦中建立某種現(xiàn)象的詳細(xì)圖像，最好的方法是給他們看一張圖片、視頻或動(dòng)畫(huà)。慶幸的是，我們今天非常幸運(yùn)，因?yàn)榛ヂ?lián)網(wǎng)上許多不同的教學(xué)資源可以用來(lái)支持科學(xué)課。在這里，我們想跟大家分享我們?cè)谖锢碚n上經(jīng)常使用的兩個(gè)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(gè)在線(xiàn)平臺(tái)，能夠讓學(xué)生在課堂上或通過(guò)遠(yuǎn)程學(xué)習(xí)獲得樂(lè)趣、參與度和影響力。在幾分鐘內(nèi)創(chuàng)建有趣的學(xué)習(xí)游戲，或者從數(shù)百萬(wàn)個(gè)現(xiàn)有游戲中選擇一個(gè)主題，復(fù)習(xí)和強(qiáng)化知識(shí)，并進(jìn)行形成性評(píng)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.
