At present, the digital literacy development of rural teachers in China has problems such as insufficient digital awareness, lack of digital knowledge and skills, and low digital application ability. As the main force of future rural education, improving the level of digital literacy of publicly-funded teacher trainees is not only important for the revitalization of rural education, but also an inevitable demand of the times. As the cradle of talent cultivation, colleges and universities should innovate the curriculum content of publicly-funded teacher trainees according to the new orientation of their cultivation objectives, innovate teaching methods, strengthen the teaching practice system of publicly-funded teacher trainees, and pay attention to the cultivation of digital awareness of publicly-funded teacher trainees and teachers' sense of ethics.
