The paper presents the findings from PRAXIS, an educational action research project developed within academic professional learning communities (PLC) in the context of public higher education in Uruguay. As a strategy towards fostering teaching innovation, we explored the potential and benefits of academic PLC for the reflection and transformation of teaching practices, and the integration of digital technologies in a meaningful way into teaching. The approach was based on Open Science (OS) and Open Educational Practices (OEP) as foundational frameworks to face the challenges of critical Educational Action Research. Key findings of the project emphasise the impact of PRAXIS framework combining OEP, OS, and academic PLC, as well as collaborative and participatory technologies for the transformation of teaching and educational research practices.
