Does anyone know what the essence of digital learning is? Is it really that good compared with traditional face-to-face learning?

The essence of digital learning is to use modern high-tech means to cooperate with electronic products through distance teaching, video teaching and multimedia teaching. Compared with the traditional face-to-face teaching, it has advantages and disadvantages. The advantage is that a round of teaching allows students to learn infinitely. Under the influence of COVID-19 epidemic, it can also reduce the close contact between students and between students and teachers, which can effectively cut off and reduce the spread of the epidemic. The teaching content of the digital teaching terminal interface can be reflected on the screen through lines, pictures, animations, physical scenes and other ways, which has vivid, concrete and vivid effects and is easy for students to understand if they listen carefully.

But the defects are also obvious. First of all, students often stare at videos, which may hurt their eyes and affect their eyesight. Because it is not face-to-face, I don't know the basic situation of each student. Because of the uncertainty of the number of students, for children who don't study hard, people sit in front of the screen, but their eyes don't know where to look, and they may not learn anything after a class. It is difficult for teachers to know this situation, and it is also difficult to teach students in accordance with their aptitude and learn from each other's strengths.
