The present study investigated whether individual or collective reflective journals could lead to teachers’ professional development and professional identity (re)construction. To this end, 30 Iranian EFL teachers were selected through convenience sampling. The participants wrote pre-workshop reflective journals individually and collectively and attended a reflective consciousness-raising workshop for eight sessions. The participants were informed about the major tenets of reflection, professional development, and professional identity (re)construction in the workshop. Afterward, they wrote post-workshop reflective journals again individually and collectively. The participants sat follow-up interviews for the researchers to find out which kinds of journals better helped them develop professionally and (re)construct their professional identity. The findings showed that individual reflective journals and collective reflective journals contributed to teachers’ professional development and professional identity (re)construction respectively. The findings might imply that stakeholders involved that is EFL education policymakers, curriculum developers, and syllabus designers hold interactive workshops for pre-service and in-service teachers on reflective journal writing which might lead to both EFL teachers’ professional development and identity (re)construction. Moreover, it is recommended that the decision-makers and senior managers develop systematic checklists addressing those influential factors found in the present study to contribute to teachers’ professional development and professional identity construction.
