If English is your native language, or even if you learned it as an additional language, you may not be aware of the structure of its sounds, words, phrases and sentences. In this module you will learn to describe how English sentences are constructed and you will develop the skills necessary to analyze sentence structure. In so doing you will use some of the tools and methods of modern linguistics. Our focus will be on how English structure is relevant to teaching English as a second language. The module is intended to deepen your understanding of important areas of English grammar and to develop competence in grammatical analysis and explanation in an ESL classroom context. Although the module will introduce insights from contemporary linguistics, no particular theoretical framework will be espoused.
