Published by the American Council on the Teaching of Foreign Languages (ACTFL), The Language Educator is intended to serve as a single, comprehensive source of news and information for educators of all languages at all levels. Usually you have to be a member of ACTFL in order to receive this publication, however several issues are available online here.
An article written by Jean Oliver that may be of particular interest to TPRS teachers is entitled “Investigating Storytelling Methods in a Beginning Level College Class.” In this article, Jean writes about using TPRS with college level students and contrasts their abilities with her traditionally taught students’ abilities. You can open the article by itself or the entire February 2012 issue of The Language Educator and scroll down to page 54 to read it.
