I really had to scrape around to find relevant articles, and you were already looking in reasonable places. It looks like the relevant literature is just sparse.
The best results I found, and they are not particularly good, were by searching in the Art Abstracts and Education Abstracts databases. Both are accessible through the All Databases A-Z directory linked from the Research Tools column on the left side of the Criss Library homepage:
The attached PDF file contains examples of how I entered searches in the two databases and a few citations from the results. You may be able to tease out additional articles by modifying the searches with different combinations of words and phrases. I usually start precisely and then broaden the scope. I also restricted results to articles immediately available online ("Full Text") and in research journals. Dropping those restrictions could increase results in the databases but would add legwork in terms of locating journals at the library or, if unavailable at UNO, requesting copies through Interlibrary Loan.
If my advice proves unhelpful, I recommend that you contact Melissa Cast-Brede (Education Librarian) or Katie Bishop (Humanities Librarian) and confer further with them. I truly don't think there is much relevant literature to find, but I could be missing a trick.
