We are pleased to present a new issue of Pedagogical Dialogue, dedicated to action research — an approach that enables teachers to critically examine their own practice and become agents of positive change within their schools.

The central focus of this issue is the NIS/SHARE project, which has brought together teachers, school leaders, and researchers around the shared goal of fostering a culture of inquiry and professional collaboration. The articles explore topics such as reflection and the development of teachers’ analytical skills, the use of digital tools for lesson observation, and the cultivation of a research culture in schools. The issue is further enriched by contributions from international scholars examining collaborative action research and the role of digital technologies in teacher inquiry. Practical case studies from schools participating in the NIS/SHARE project showcase diverse approaches to implementing research-informed initiatives in educational settings.

We hope that the materials presented in this issue will be valuable to teachers and contribute to the further development of research culture in schools.
