Research on the Restrictive Factors and Strategies for Improving the Teaching Ability of University Teachers under the Background of Education Digitization

Education digitization deeply integrates modern information technology with education, innovates the traditional teaching mode of universities, and makes higher education glow with new vitality. At present, the digital transformation of higher education has become a research focus of higher education reform. Therefore, the digital teaching ability of university teachers has become an indispensable force. It is not only conducive to the construction of college teachers but also conducive to the improvement of university teaching quality, which is a key factor related to the quality of higher talent training in the new era. Therefore, whether university teachers can adapt to the development of digitalization and how to improve their digitalized teaching ability are worthy of attention. Based on this research background, this paper tries to summarize the new requirements of digital transformation of education for teachers' teaching ability by reading relevant literature of the Ministry of Education and taking TPACK theory as guidance. Then, combined with the existing investigation and research results, using case analysis and comparative research, this paper summarizes and analyzes the constraints that affect the development of teachers' abilities from both internal and external aspects of teachers. Finally, based on the analysis of the constraints, suggestions are put forward from the perspectives of teachers' teaching cognition, teaching behavior, school training organization, evaluation system, and digital construction.
