The RemixED platform (https://remixed.upf.edu/) has been developed across the project lifespan using an iterative approach. This approach involved target end users (educators) from the onset to help define requirements and test features and functionality along the way. 

The aim for the platform is for it to be used by teachers participating in RemixED teacher professional development courses – as the platform has been conceptualized to support teacher learning in the course and their sharing of work performed during the course. The sharing component involves publishing outputs of teacher learning for the benefit of the educational community and incentivizes teacher commitment to the professional development course.
