The emergency transition to online learning in the wake of Covid-19 was a phenomenon that forced schools to switch to remote teaching overnight. This emergency transition to online learning has not only been a short time solution to the disruption in the global education, but remained over a year, proving itself to be a significant tool for continuous and accessible education. For one side, the Covid-19 educational emergency brought many opportunities for online learning but at the same time highlighted many of the problems that already existed. Transitioning to online learning, especially when university curricula are planned for face-to-face (F2F) teaching and learning, requires careful planning and design processes. In the last spring semester, we experienced a first phase called Emergency Remote Teaching (ERT) a term coined to describe the lack of planning, design, and student-centred approaches. However, it is worth noting that this situation has created opportunities for the adoption of digital pedagogy and the development of digital literacy: an absolute majority of academic faculty has already experimented with ERT. Nevertheless, in order to implement online learning, the teachers need constant support and professional development opportunities to facilitate the transition from ERT to online learning. We apply this project, CLOSER, to address and provide this imperatively needed support to the teachers and educators in different countries of Europe through creating evidence-based, open, and innovative practices of teaching and learning.
