Why are online classes always stuck?

1. Problems with teachers’ computer hardware equipment.

Some teachers use laptops to access the Internet at home. Most of the laptops used by teachers are priced at RMB 10,000 or less. They can be used for daily office work, but once online classes are held, It is a bit stretched. Of course, it is absolutely unrealistic to replace the equipment now. So, can we optimize it as much as possible based on the original equipment? Of course there are methods.

The first thing to do is to uninstall the uncommon software on your computer, especially some anti-virus software. In fact, the built-in protection functions of the win10 system are enough, and installing anti-virus software is really superfluous. suspicion. The next step is to disable all irrelevant applications. Many teachers don’t pay much attention to this. They always feel that their computers are not running other software. In fact, this is not the case. As long as you click on the upward symbol in the lower right corner of the computer desktop, you can see how many temporarily useless programs there are. After running, right-click to exit or close one by one.

The main cause of lag on the student side is network speed and equipment problems. Therefore, students should try to follow the solutions mentioned above during online classes. At the same time, if there is still lag, please check whether the live broadcast on the student side is There are smoothness setting options. For example, DingTalk has options such as ultra-clear, high-definition, standard definition, smooth, and extreme speed. Select Extreme Speed ??to see if there is any lag. Of course, if the teacher's teaching is stuck and the teaching is stuck, it cannot be solved by the student side. Therefore, when the student side is stuck, first ask other students whether their devices are stuck before making a judgment.
