The number of people in traditional classroom teaching is limited, while online courses can accommodate thousands of learners at the same time, so that more people can receive high-quality education.

Secondly, the openness of online courses also makes education more fair. No matter where learners are, as long as they have access to the Internet, they can enjoy free high-quality educational resources. This provides new opportunities for those who cannot receive traditional education because of geography, economy and other reasons.

Learners can choose their own learning content and schedule according to their learning styles, interests and schedules. This personalized teaching method is helpful to improve learners' learning effect and learning experience.

Generally speaking, online courses, such as massive open online courses, have far-reaching influence on education and teaching. They provide opportunities for more people to receive quality education, and also provide new ways and means for education and teaching. However, we also need to see the problems and challenges and actively seek solutions.
