1, welfare.

It breaks the restriction of venue rent and student flow on offline teaching and makes full use of the advantages of multimedia. Usually offline education is limited by geography and teachers, and it is difficult to achieve educational equity, while online education can have the opportunity to achieve relative educational equity.

In real life, there are many teachers, few good teachers, many schools and too few good schools. Online education can give more people access to high-quality educational resources, and even freely combine the courses they want to learn according to their own needs, without being bound by real life.

2. Disadvantages.

The biggest deficiency of online teaching is the lack of interaction between teachers and students. Because there is no face-to-face class, there will be no real-time interactive feedback between students and teachers.

For the teachers in the classroom, it is only a unilateral teaching process. Teachers can't interact with students, and they don't know if students understand. Without interaction, it is difficult for teachers to grasp the depth and speed of classroom content, and it is easy to become unilateral teaching, which will greatly reduce students' learning.

Introduction to online education:

1, origin.

With the rapid development of information technology, especially from the Internet to the mobile Internet, it has created a way of life, work and study that spans time and space, and fundamentally changed the way of knowledge acquisition. Teaching and learning are not limited by time, space and place, and the channels of knowledge acquisition are flexible and diverse.

2. Development potential.

Everyone can't live without education: early education, extracurricular tutoring, children's English, vocational education, studying abroad, business school, and immigration services. With the explosive development of information technology, the advantages of online education are increasingly prominent. Online education can break through the limitation of time and space and improve learning efficiency.

3. Learning form.

Teachers and students, students and students communicate in all directions through the network, which narrows the psychological distance between teachers and students and increases the opportunities and scope of communication between teachers and students. And through the computer, the type, quantity and frequency of students' questions are statistically analyzed, so that teachers can understand the doubts, difficulties and main problems that students encounter in their studies and guide students more pertinently.
