Abstract: Teachers' workload is not a product of modern education;it has emerged with the emergence of schools and full-time teachers.Later,it changed with the changes in social environment and teaching technology.Under the trend of digital education,digital technology is profoundly changing the form of teachers' workload.From the perspective of "accelerated critical theory" and path dependence,in the long run,digital technology can reduce teachers' workload and improve work efficiency in the whole teaching process from pre-class preparation to effect evaluation.Although the application of digital technology has promoted the reform and development of education,and also provided more teaching resources and tools for teachers,it cannot completely reduce teachers' workload independently.In this regard,education management departments and schools should strengthen the construction of digital infrastructure,formulate standards and management norms for digital teaching resources,explore long-term mechanisms for workload reduction by digital means,and assist teachers to improve their digital technology capabilities.Teachers should break through path dependence,actively learn and apply new digital technologies while continuously improving their practical and management abilities in digital technology.The three parties should fulfill their main responsibilities and form a joint force to fully leverage the supportive role of digital technology in educational practice.

Key words: digital technology, teacher, teachers' workload, education, education digitization, labor alienation
