With the rapid development of artificial intelligence technology and the popularization of digital education

the field of education is undergoing profound changes. The digitalization of education has not only changed teaching content and methods

but also altered students' learning habits and needs. As core practitioners of educational digitalization

the digital literacy of college English teachers urgently needs to be improved. This study explores how to enhance the digital literacy of college English teachers from three aspects: constructing a multidimensional support system

strengthening teachers' autonomous development momentum

and empowering personalized teaching innovation with digital intelligence technology

thus effectively improving students' critical thinking ability and cross-cultural communication ability.
