This document has been commissioned by the ERIC Clearinghouse for Linguistics to provide an overview of resources, methodologies and activities in the field of Teaching English to Speakers of Other Languages. The author points out the contributions made by various approaches to language teaching and the new insights into language arrived at by different schools of linguistic thought. He also stresses the need for greater research on many levels. His introductory review of the field of TESOL in the last twenty years is followed by: a list of historical reference materials; major bibliographic sources of information on teaching materials, texts, and articles on English language teaching; and a selected list of elementary, secondary, and adult level texts "which have been found to be useful by teachers." The second section of the paper, "Linguistics and Language Teaching," discusses in some detail the relationships between sets of model sentences in the light of transformational generative grammar. Following sections discuss "Psychology and Language Teaching,""Language Teaching Pedagogy,""Linguistics, Psychology, and Pedagogy,""Teacher Training," and "Teaching a Second Dialect." Each section contains or is followed by references to materials of particular interest to the classroom teacher. (AMM)
