Last year I was part of a team that ran a course at P2PU called “Why Open?”, in which we discussed the various meanings of openness, engaged in some open practices, and talked about potential benefits and drawbacks/obstacles to openness.
We’re running it again starting August 10, and registration is open now!
You can see the course itself at https://p2pu.org/en/courses/2314/why-open/
Or read a blog post summarizing it at the School of Open blog.
Last year I learned a lot from participants, and expect to do so again this year!
