Choose a live broadcast platform for online training, and the functions of the live broadcast platform should be at least comprehensive; Satisfied with the interactive function of teaching; In addition, the stability and data analysis of the live broadcast platform should also have an introductory stage. You only need a network cable and a computer to start the live broadcast of teaching and training, which is especially suitable for teachers to teach at home. Except for courses that require professional software such as design and animation, ordinary on-site teaching and training generally do not need particularly strong performance, and ordinary home desktops and laptops can meet it. If the lecturer needs to change the venue frequently, or has requirements for portability, it is recommended to bring a laptop with a camera and microphone, without extra purchase. If you don't need to type, you can stand up and give a lecture, just like on the podium. With a stylus, you can write and draw on PPT at any time and mark the key points. The network situation will directly affect the stability of live teaching. At present, the general home broadband is about 5M~ 10M, which can basically meet the needs of lecturers. After the required hardware environment is equipped, a professional teaching live broadcast system is also essential for normal classes.
