Exploration and Reform of “Online+Offline” Blended Teaching in Science and Engineering Courses Based on Artificial Intelligence

“Online+Offline” blended learning has produced significant benefits in higher education teaching, but currently there are problems such as a single mode and difficulty in effectively integrating with AI technology. Based on this, this article proposes a reform and practical exploration of “Online+Offline” blended learning based on artificial intelligence. It mainly elaborates on the organic integration of artificial intelligence and blended teaching from three aspects: mode reform and practice, online and offline feedback reform and practice based on AI big models, and online library resource reform and practice. The research content of this article will provide reference for opening up new “Online+Offline” blended learning models.
