The document discusses methodological trends in English language teaching, from traditional grammar translation to more modern approaches like the Direct Method and Audiolingual Method. It analyzes Francois Gouin's Series Method which taught connected sentences conceptually without translation, and how this influenced the Direct Method which emphasized oral interaction and inductive grammar learning in the target language. Finally, it describes how the Audiolingual Method developed from military language programs and drew on structural linguistics and behaviorism to focus on pattern drills and habit formation.
