"presentation in..." or "on..."

[skya]

Hi, I'm writing a sentence about how we benefited from showcases and presentations. I wrote:

"We benefited from showcases in listening and reading material development and presentations on curriculum design for study abroad programs, including in ways to promote task-based language use outside the classroom and how to use using movie clips in different levels."

Do you think it's right to use "in" and "on"? When should we use "in" or "on"? Thanks!
Best,
Skya

'Showcase' is something of a neologism: I'm not sure whether there's any formally fixed preposition, but 'on' sounds better to my ear than 'in'...
