Abstract: As a technology-intensive subject, the electrical and electronic courses adopt an online and offline blended learning model, combining traditional face-to-face teaching and modern online learning resources to provide students with a more flexible and diverse learning experience. Based on the basic concepts and application advantages of online and offline blended learning mode, this paper investigates and analyzes the current application status of online and offline blended learning mode in electrical and electronic teaching, and proposes how to further optimize the application strategy of online and offline blended learning mode in electrical and electronic teaching, and the research results can provide strong guidance for teaching innovation in the field of electrical and electronic education, and improve students′ academic performance and career development prospects.
