Centering on a qualitative study of three female English teachers in Shanghai, China, the book explores female language teachers' perceived discrepancies and agency exercised in their teaching, research and teacher learning practices. By adopting multiple research methods, such as narrative questionnaire, metaphor, timeline, interview and classroom observation, this study reveals that female language teachers' agency is a dynamic entity manifested in the ongoing negotiation of agency belief, agency practice, and agency inclination, as well as the interaction of individual and the environment. Though there are certain limitations concerning representativeness and generalizability, the author provides a thick description of how female language teachers in China are exercising agency to fulfill their career development, which offers insightful suggestions to language education in both China and broader areas globally. The book will appeal to researchers studying teacher education and foreign (English) language teaching, university teachers, especially female foreign language teachers, PhD students and graduate students, as well as career women.
