Hi @wernerio
Its been a few years since we had contact - great to see you here and catch up with the amazing work you are doing.
Been thinking a lot about this in the K-12 context as we embark on capacity development initiatives in the Pacific for school teachers.
I think a productive starting point is to have two or more teachers working on the same OER resource for reuse in their respective classrooms from different contexts, eg two different countries. This provides an authentic context to design for remix.
Interested to hear your thoughts on how would you tackle this challenge in the South American context?
