Grammar for Teachers: A Guide to American English for Native and Non-Native Speakers is a result of my frustrations over many years of teaching graduate-level structure courses and not being able to ?nd an appropriate grammar text for the pre- and in-service teachers enrolled in these classes. The students in these courses have represented a variety of teaching backgrounds: ESL and EFL teachers, native and non-nativespeakersof English,and mainstreamcontent-areateacherswith ESL students in their classes, to name a few. Some of these students have had a strong knowledge of English grammar, but often have dif culties in applying their kno- edge to real-life discourse. Other students exposure has been limited to lessons in correctness, and are generally unaware of which language features are central to teaching ESL/EFL learners. Some students are resistant to taking this course, but are required to do so, whether to satisfy speci c degree requirements, for state or professional certi cation, or for other reasons. A few students have had some l- guistics, many not. The challenge has been ?nding a way to convey the essentials of AmericanEnglishgrammarclearly,toengagestudentsactivelyin theirownlearning and understanding of grammar as applicable to ESL/EFL learners, and to motivate them to undertake perceptive analyses of grammatical elements and structures, and of ESL/EFL learner needs and dif culties. The overall aim of Grammar for Teachers is to make grammar accessible and comprehensible.
