The history of language teaching has been characterized by a search for more effective ways of teaching second or foreign languages. For more than a hundred years, debate and discussion within the teaching profession have often centered on issues such as the role of grammar in the language curriculum, the development of accuracy and fluency in teaching, the choice of syllabus frameworks in course design, the role of vocabulary in language learning, teaching productive and receptive skills, learning theories and their application in teaching, memorization and learning, motivating learners, effective learning strategies, techniques for teaching the four skills, and the role of materials and technology. Although much has been done to clarify these and other important questions in language teaching, the teaching profession is continually exploring new options for addressing these and other basic issues and the effectiveness of different instructional strategies and methods in the classroom.
