1, when opening an online class, first understand the operation mode of the website. We need to look at the control panel at the bottom of the video. Usually there will be a fast forward function key here. If not, you can also skip or advance the video through the → shortcut key on the keyboard. It should be noted that the size of fast-forward should be moderate, and don't cross the key content.
2. What if there is no fast forward function? We can choose to use an extension of the browser. For example, Chrome browser can fast-forward online video by downloading video control plug-ins. There are also some softwares that specialize in video acceleration, such as PotPlayer and KMplayer, which can realize the function of video fast forward. When using these softwares, we should pay attention to choosing formal channels to download and ensure the security of the computer.
Besides software and plug-ins, we can also use the player that comes with the system. In Windows system, we can use Windows Media Player, and in Mac system, we can use QuickTime Player. However, these players need to read the instructions of fast forward. In general, it takes a long time to press the fast forward button to achieve the fast forward effect.
4. If you want to improve the video playback speed, you can also try to use the fast-forward plug-in in the video player. Common plug-ins are displayer, PotPlayer and KMPlayer. When using these players, we need to choose the speed of 2 times or higher, but don't choose too high, we should choose the corresponding multiple according to our listening speed.
Several forms of online education courses;
1. Video course: There are five basic courses: video, document, picture, animation and audio. Different forms of curriculum expression have their own characteristics and uses. Sometimes the same course, different forms of expression, or several forms of alternate use, the effect is not the same.
Video course is suitable for the reproduction of real scenes and the study of logic teaching content. Both recorded and broadcast courses and live broadcast courses belong to video teaching, such as Tai Chi moves and painting demonstrations. Compared with animation and audio, video can provide learners with an intuitive teaching experience.
2. Documentation course: Documentation course is suitable for basic concepts or factual statements. For example: terminology learning, solution and so on. It can be designed as a document to present, which is more convenient for learners to read and learn.
3. Picture course: Picture course is more suitable for vivid and intuitive learning content. Compared with simple words, pictures can attract learners' attention more. "Concept or fact content+picture" can better spread knowledge, such as traffic rules.
4. Animation course: Animation course is suitable for learning the content that needs visualization. It is common in children's education, and animation files are usually small, which is more suitable for mobile terminals to download and save. But the cost of animation needs to be considered, and the content of the story also needs to be studied and considered.
5. Audio course: Audio course is suitable for learning with sound presentation. Language is the most commonly used category, such as English conversation, tourism language, language training and so on.
