I am very interested in this! I am currently having conversations with a professor at the Royal institute of Technology here in Sweden about something similar to this. He would like to restructure the idea of what the grades at uni are actually rewarding. We're currently rewarding knowledge oneself is possessing rather than encouraging the dissemination of knowledge, which this professor is interested in. We were talking about the possibility to grade successful dissemination of knowledge rather than the ability to write down what one has in her or his head in an exam. So there would be a societal gain where grading is based on telling and sharing of the knowledge one has acquired, which can be done in various ways, rather than encouraging the current system with exams and such.
This would, in this aspect, be rather interesting. Thank you for sharing!
