During the epidemic, Tencent conference, zoom and nailing were used, and finally it was replaced by a small desk. I found that Tencent Conference, Nail and zoom are all aimed at conference mode, not at teaching. The following is my personal experience:

1. Do you want to switch with ppt, in ppt? It is too hard to explain the pictures of the courseware, and it needs to be cut between windows, which feels that it is not designed for courseware or blackboard mode;

2.？ In class, I will be disturbed by foreign news, unable to concentrate on the class, and have no sense of immersion at all, which not only affects the teacher's lectures but also affects the students' lectures;

3. The content of the picture is gone after it is over, and then it is gone. Sometimes, there is no way to get the content of the explanation out for the knowledge points after class, and there is no way to review the content of the explanation. ? I used and switched among various teaching software, and finally chose a software called small desk. This is its official website (/xkz/). I downloaded it from this link, which fully meets my needs. It also has the function of managing students. The following is a screenshot of my use. This software has many brush types and many colors to choose from. Simple and easy to use, video courseware can be added, and the video playback picture is the same as the original video.
