As one of the latest research hotspots in the field of artificial intelligence, AI-generated content (AIGC) can create virtual teaching scenarios, such as those involving educational digital humans, through content creation. This integration of AI and education is a product that will profoundly change the form of online education and the learning experience. Currently, most courses for educational digital humans still rely on traditional educational models and face many problems in practice. Based on an overview of AIGC technology and its application in micro-course production, this paper analyzes the current status of micro-courses for educational digital humans. It proposes the application of AIGC technology and educational digital humans in micro-course production, namely, using AIGC technology to drive the transformation of micro-courses for educational digital humans towards intelligence, thereby improving education quality and efficiency.
