In this study, I explore my practices as a teacher educator in one course both before and after returning to the K-12 classroom to teach secondary language learners for one academic year. By examining the intersection of self-study and practice-based teacher education, I illustrate how I used self-study as a mechanism for innovation and change and focus on the challenges I encountered in implementing the use of practice-based education in my work as a teacher educator. Qualitative data analysis revealed that in redesigning my approach to my course, I stopped short of my goals to make the course more practice-centered. Although I provided students with many opportunities to practice planning, I did not provide enough focused opportunities to practice implementation and to participate in giving and receiving feedback. I learned that engaging teachers in practice-based teaching requires teacher educators to be both specific and deliberate in setting their own purposes for establishing the centrality of practice in their courses and to explain these clearly to teacher candidates. Further work in which teacher educators study their use of practice-based pedagogy would benefit from using a self-study lens. Other researchers are urged to add to the limited body of research about the use of practice-based pedagogy with teachers of language learners, particularly English language learners.
