Affected by the epidemic, offline classes are changed to online classes, so students can go online at home, so they don't stop classes.

Online education, or distance education and online learning, generally refers to a network-based learning behavior in the current concept, which is similar to the concept of online training.

Advantages of online courses:

1, without time and space restrictions. The biggest difference between online education and traditional education is that you can complete your study anytime and anywhere without the restriction of offline learning conditions and environment. Many people choose online education because they value the advantages of online teaching, which can save a lot of unnecessary time and facilitate students to finish their studies better.

2. Effectively solve the problem of uneven teaching resources. The biggest problem of education at this stage is the imbalance of teaching resources. The teaching resources in first-and second-tier cities are too different from those in other regions, which greatly widens the teaching differences in major cities under the same study time. Online education can solve the problem of unbalanced teaching resources. Although it is less than the backward areas, it can solve the problem of teaching resources in most cities.

3. Diversified curriculum system. Compared with a single course in traditional education, online courses are more diversified, with multiple course systems running and managing at the same time, and the course design is more diversified. Students can choose online courses reasonably according to their unique learning needs. In addition, online courses can keep up with the update speed of the times and optimize the curriculum system in time.

4. Enhance students' initiative in learning. Due to the particularity of online learning, students are more independent in course selection and more active in the learning process, which also strengthens the enthusiasm of students for active learning.

5. Platform tools assist teaching management. Online teaching can be managed by platform tools and assisted by institutions. For example, it is more convenient and efficient to query students' learning, payment, homework completion, examination and other management links with the help of the platform.

Disadvantages of online courses:

1, lack of emotional communication. The Internet gives people a cold feeling. There is not much emotional communication, and there is less viscosity between institutions and students. Online teaching is also difficult to completely reproduce the learning scene of face-to-face exchange learning under the line, and teachers and students can't know each other's real thoughts in time.

2. High demands on students. Different from the real-time learning supervision in offline learning, online learning requires students to have more learning autonomy. Even though the current teaching platform can solve the problem of real-time video and voice interaction, it lacks the restoration of real social scenes. Therefore, students need to have good self-control and adapt to the online learning environment quickly.
