A Tale of Three Excellent Chinese EFL Teachers: Unpacking Teacher Professional Qualities for Their Sustainable Career Trajectories from an Ecological Perspective

Teachers' quality has long been researched in the field of general education. However, little attention has been paid to the professional qualities of excellent English as a foreign language (EFL) teachers in the context of English curriculum reform, especially from an ecological perspective. To address this gap, this study adopted a qualitative approach to characterise the qualities of excellent senior high school EFL teachers in China and the development of their professional qualities using Bronfenbrenner's ecological systems model. Four interconnected dimensions of excellent EFL teachers' professional qualities were confirmed: English language pedagogical content competence, beliefs about the foreign language teaching profession and professional ethics, beliefs about foreign language teaching and learning, and beliefs about language teacher learning and development. Meanwhile, the EFL teachers constructed and developed their professional qualities in their dynamic interaction with the complex ecological systems where they lived. The paper considers these various teacher-related factors in the ecological systems and provides some suggestions for sustaining EFL teachers' professional development.
