Should we allow/endorse questions asking for feedback on a lesson plan/lab/other class activity? For teachers, having peer review on various aspects of designing a course could be very helpful and useful to future visitors, especially new teachers. This would fit into the Stack Exchange philosophy of creating a repository of knowledge. Obviously we'd have to be especially careful not to permit broad questions here (e.g. "Plz right lesson plan for me for tomorrow"), and we'd have to make sure that the questions stay high quality, but that's a responsibility we already have with the existing Q&A.
This is not a standard use of Stack Exchange Q&A, but it's been done effectively on CodeReview.SE and I believe that it could be effective and useful here. I don't see how it could hurt the site (as long as we curate carefully) and I think that such questions would help to attract a wider group of teachers to this proposal without broadening the scope.
If we do permit this use of the site, I suggest that we carefully confine it to a tag, for example "review" (other tag name suggestions are welcome, review could be too broad of a name)lesson-ideas already exists and has a similar question.
An example lesson-ideas question could be:
I am teaching a lesson on x. How can I better express y?
I was going to start with activity x, then explain y, them check if they know z.
Specifically, I think my students my struggle to understand x without knowing y. Should I change the order? Should I first teach q?
