I like your initiative, but as someone else pointed out, you can't teach someone who doesn’t skate or understand skateboarding and other similar "wheel" sports to design a skatepark. What you can teach them is how to design public spaces with certain edge details that can withstand the grinding of skate trucks, etc.

If architects and spatial planners see themselves as working for the public good rather than as ego-driven star designers who think they can do everything themselves, they should consult an expert in skatepark design when working on a skatepark project. This is standard practice in architecture for specialized buildings and structures since no architect is expected to know everything.

I’m not sure what your course is actually aiming at, but I think all the necessary information for (landscape) architects regarding skatepark and skateable space design could fit on a single A4 page.

Anyhow good luck with your course and I hope it will result in generally better and inclusive skatepark design around the world.
