In recent years, China has vigorously promoted the national digital education strategy. As of now, the number of online MOOCs has exceeded 76800, with 454 million registered users. 415 million students have received MOOCs credit recognition, serving 1.277 billion people in China for learning. The scale of construction and application ranks first in the world, and the public service capacity of education has significantly improved. As an important breakthrough for China to open up a new track of educational development and shape new advantages in educational development, digital education provides strong support for personalized learning, lifelong learning, expanding the coverage of high-quality educational resources, and modernizing education, making significant contributions to the overall level of education modernization development in China. MOOC, marked by large-scale open online learning, is one of the important carriers of digital education. Through the advanced planning and strong guidance of the Chinese government, and after more than ten years of unremitting efforts, the goal of everyone learning, learning everywhere, and learning at all times has been basically achieved, greatly expanding the boundaries of education. With the rise of the short video economy and the iterative upgrading of mobile terminals, recorded and broadcasted MOOCs have played a significant role in higher education and continuing education, as well as in basic education, especially in primary and secondary school teaching and research. Both short video courses and live courses have played a significant role in social education and have produced good results. It can be said that with the solid platform formed by MOOCs, the concept of lifelong learning for all is becoming a reality. "In the academic field of an era, there must be new materials and new problems. Using this material to study problems is a new trend in the academic field of this era." Chen Yinke's statement from that time still has practical significance to this day. The transformation of education is no exception. The massive amount of MOOCs and video resources provide endless "new materials" for the current educational transformation. In recent years, the rapid development of artificial intelligence has posed "new problems" to education. How to combine the two and create a new form of education that is more in line with educational principles, laws, and spirit is the mission of education in the era of digital intelligence. In the era of digital intelligence, education not only continuously innovates teaching scenarios and improves teaching quality and efficiency with the support of massive resources and convenient terminals, but also leads to a sharp increase in the number of learners and learning frequency; Through artificial intelligence empowering education, AI growth assistants, AI life mentors and other means, a good social scene has been achieved where everyone can learn, everyone is eager to learn, and everyone enjoys learning. What is even more anticipated is that, with the dual support of artificial intelligence technology and open and shared online resources, the spirit of classical education and modern education are accelerating their integration, revolutionizing both the concept and form of education. In future digital education, we will see the unity of "teaching", "learning", and "questioning" as stated in the "Book of Rites - Xueji", which states: "A good scholar, a teacher who is easy to learn, will achieve twice the result; a bad scholar, a teacher who is diligent, will achieve half the result; a good questioner is like attacking a sturdy tree, and a kind questioner is like striking a bell."; We can also see the unity of "teaching", "learning", and "doing" as Tao Xingzhi said, "the method of teaching should be based on the method of learning, and the method of learning should be based on the method of doing."; We can better see the new version of the Compulsory Education Curriculum Plan (2022 version) which states "comprehensively promoting exam evaluation based on core competencies and strengthening exams"
