E-mail: wanyingbnu@163.com EACHER knowledge sharing is a process in which teachers collaborate to boost their understanding and construction of knowledge by integrat- ing fragmentary knowledge owned by individuals into a shared knowledge system. It helps promote common development in teachers as well as en- hance the school’s quality of knowledge base as an educational community. Nevertheless, the teacher may tend to keep their knowledge private to main- tain their professional distinctiveness. Also, educational and instructional ex- pertise is often interwoven into the education process, and its implicit nature is an impediment to its sharing. Hence, teacher knowledge sharing has be- come a pronounced issue in modern school management. Recent research in this area reveals that the principal leadership style has a significant impact on the teachers’ knowledge sharing behavior. This study investigates the rela- tionship between principal authentic leadership and teacher knowledge shar- ing, as well as its influencing factors, from the perspective of the self- determination theory. Research Findings: • Principal authentic leadership can positively predict teacher knowledge sharing. This leadership style ensures the security of the behavior of publicly sharing information in teachers and prompts their realization of the significance of mutual support. • The effect of principal authentic leadership on teacher knowledge sharing is moderated by the teacher’s perception of insider status. Stronger perceptions of insider status elicit positive behaviors in teachers; enhanced teacher perceptions of organizational member- ship lead to significant elevation of the knowledge sharing inten- tion in them. • Social-emotional skills of teachers mediate the relationship be- tween principal authentic leadership and teacher knowledge shar- ing. Principal authentic leadership is effective in improving the so- cial-emotional skills of teachers, driving them to showcase their value by sharing information with co-workers.
