This study explores two higher education-based language teacher educators' teaching beliefs and how they implemented their beliefs in classroom practice. Drawing on data from in-depth interviews and classroom observation, the findings revealed the teacher educators' multiple and complex beliefs, which were derived from their past experiences and continued to be shaped and transformed through their professional work. The study also shows that while the participants tried to act in accordance with their beliefs in their teaching of teachers, they encountered some contextual obstacles (e.g. the 'publish-or-perish' system) which resulted in the gap between their beliefs and practice. Through their continuous reflections and agentive work, the teacher educators tried to close the gap and facilitate their students' learning to teach. This study concludes with some implications for current teacher education and higher education on how to promote language teacher educators' cognitive learning and continuous development.[Copyright © 2016 Informa UK Limited, trading as Taylor & Francis Group.]
