It is necessary to analyze the advantages and disadvantages of live and recorded classes respectively.

First of all, talk about the recording and broadcasting class.

1, has been learning:

With the sharp decline of PC-side traffic, the sharp increase of mobile-side traffic, the popularity of large-screen mobile phones, and the reduction of traffic costs, one direction of online education in the future is to learn anytime and anywhere, using students' fragmented time to learn, such as learning a knowledge point in a five-minute micro-lesson. Recording and broadcasting courses are one of the main carriers of online education content and an indispensable part of future online education.

2. "Interaction" comes from the secondary link of education;

Online education module, imparting knowledge and skills, learning is the ultimate goal. Nowadays, many educational institutions have applied many interesting interactive functions in recording and broadcasting courses, such as question-and-answer function and barrage function. There will be more and more interactive function development of recording and broadcasting courses in the future. The quality of courses and the interaction with teachers and classmates will become the key for institutions to seize students, so the future of recording and broadcasting courses should not be underestimated.

3. Recording and broadcasting courses can create excellent content:

From the perspective of the education industry, recorded and broadcast courses can be prepared in great detail in advance, and the editing can be optimized later. As long as careful preparation is made before video recording and broadcasting, a course with rich content and interesting activities can be made, which is impossible for live courses. Moreover, the course content can continue to bring value to enterprises and attract students, and students' questions after class can be arranged and answered in a unified way. Put important resources on key courses, and the average resources allocated to each student will be very small. On the contrary, for enterprises and students, better learning results can be obtained.

Compared with recording and broadcasting, the main bottlenecks at present can be divided into the following points:

1. The live class requires students to study in a fixed time. If you miss the live broadcast time, students can only watch the class through video playback, and some small actions of the teacher in the live broadcast class will reduce the video quality, thus affecting the video experience.

2. The interaction of live class is a waste of time. From the perspective of our offline education, the interaction between students, teachers and classmates will affect students' learning status and interrupt students' thinking. Compared with recording and broadcasting lessons, the learning effect is greatly reduced, and the time cost is higher, so the fragmentation time can not be used well.

3. The future development experience of the live class on the mobile side is not good. At present, most live classes must be taught on the pc side, and the mobile side has a poor video experience compared with the recorded class in terms of interface and interaction.

4. From the institutional point of view, the live class requires higher course content and recording hardware. Live lessons alone consume much more resources than recorded lessons and produce less intuitive value.
