I never found the time to get my ideas together for publication, but I just found an article where someone else has:
Conteh-Morgan, Miriam. 2002. "Connecting the Dots: Limited English Proficiency, Second Language LearningTheories, and Information Literacy Instruction" The Journal of Academic Librarianship, Volume 28, Number 4, pages 191-196. (http://vnweb.hwwilsonweb.com/hww/results/external_link_maincontentframe.jhtml?_DARGS=/hww/results/results_common.jhtml.42)
Some quotes from the article (p. 195): "A basic understanding of second language teaching theories seems fundamental to improving librarians' ability to teach better . . . "
"[I]nsights from this area of research and practice can help them design a course that is more linguistically, socially, and culturally responsive and thereby create a more rounded learning
experience for LEP students."
