Research on the promotion strategy of teachers' digital literacy under the background of education digital transformation

With the continuous advancement of the digital transformation of education, teachers' digital literacy has become an important factor affecting the quality of education and teaching innovation. Teachers' digital literacy not only includes technical operation ability, but also covers multiple dimensions such as information processing, educational innovation and teaching design. This paper conducts an in-depth study on the current situation, challenges and strategies of improving teachers' digital literacy under the background of digital transformation of education, and proposes specific countermeasures to promote the improvement of teachers' digital literacy. The study found that the improvement of teachers' digital literacy requires not only improving their information technology capabilities, but also changing traditional educational concepts and teaching models. By analyzing relevant policies and practical experiences at home and abroad, this paper proposes a phased and hierarchical training program, as well as a combination of practical operations and case teaching, aiming to provide scientific basis and practical guidance for the improvement of teachers' digital literacy. The research results show that systematic training, strong technical support, and policy guarantees are the key to the continuous improvement of teachers' digital literacy.
