In this paper we present and discuss the action research we conducted with the main purpose to investigate the proper ways to introduce action research to our student-teachers in the university so as to empower them in a lifelong professional development perspective. Although the obstacles we faced were many, it seemed possible and beneficial for our students to get involved in real action research projects in the framework of an undergraduate course. They had the chance to appreciate the theory and practice link, to investigate their implicit theory, to construct collective knowledge and to participate in reflective practices.
