Action research is characterized by a new paradigm of empowering teachers to monitor their own practices in a more autonomous manner with a vision of challenging and improving their own techniques of teaching through their own participatory research. Yet in spite of this apparently radical shift in the function of the teacher from the constant consumer of scientific theories to a researcher, as envisioned, the concept of action research as an in-service teacher education strategy has not received due attention in practice. For this reason, the presented case study was undertaken to examine whether the notion of action research by teachers was a viable option for in-service teacher development in a highly centralized education system. More specifically, this paper sought to answer whether teachers have any vision of what they can achieve with action research, whether there is scepticism on the part of teachers about the effectiveness and feasibility of action research as practice-based undertaking, and whether there are inherent structural problems that preclude teachers from undertaking such a role. Three English Language Teaching teachers were involved in this action research. The findings indicate that teachers, being capable of carrying out action research, were quite positive about action research and hopeful for overcoming some inadequacies in their educational environment, making it an asset for personal-professional development despite a highly centralized education system.
