However, the long-term effects of action research as a professional developmental strategy has not been specifically investigated in an English as a foreign language (EFL) context. Taking this gap as an impetus, this study aimed to investigate the long-term effects of action research on teachers’ professional development and instructional practices. The study also aimed to explore how action research is conducted by Turkish EFL instructors and the most effective ways of implementing it. The study was carried out with the participation of eight EFL instructors working at various departments of universities in Turkey. These universities were Bilkent University, Middle East Technical University, Hacettepe University, Anatolian University, and Near East University. The data were collected through semi-structured interviews, and analyzed qualitatively Analysis of data revealed that action research engagement may contribute to teachers’ classroom practice and professional development in the long run and in many ways. The findings also revealed that although the teachers followed a systematic process while conducting action research, they did not always share the findings of their studies, which is considered one of the vital steps of action research processes. Another finding was that individual teacher research is more commonly implemented than other types of action research, collaborative or schoolwide action research. In addition, it was also seen that having the guidance and support of a mentor, colleagues, and administration in a supportive context is considered crucial for the effective implementation of action research. Finally, the findings of the study revealed that the teachers who had advanced degrees appeared to have more positive attitudes towards action research than the teachers who had only BA degrees. In the light of these findings, it can be said that school administrators and teacher training units should seek opportunities to promote the implementation of action research in schools, which would result in better outcomes in teaching practices and student learningxiii, 120 leavesEnglishinfo:eu-repo/semantics/openAccessaction researchcollaborative action researchprofessional developmentPE1068.T8 O95 2011English language--Study and teaching (Higher)--Turkish speakers.English teachers--Training of--Turkey.Thesis
