Journals as Repositories

Ever since we published our lessons I've been wondering why journals like CourseSource aren't the norm. Academics invest a lot of time in creating teaching materials, just as they do with data and code: why aren't they trying to get as much recognition for their work on lessons as they now are for their work on the latter? Whatever the reason, I think peer review (pre-pub or post-pub, anonymous or not) is the obvious next step for our lessons, and I'm going to push for us to do this with the next version of our material.
