Book excerpt: In this book, the author looks at what's wrong with the way grammar has been taught traditionally, and outlines current theories, research, and principles underlying grammar instruction for writing, advocating that grammar instruction be incorporated throughout the writing process, not broken out into isolated units. She offers teaching ideas and lesson plans for primary and secondary students, and gathers practicing teachers to describe their methods for responding to student errors, helping English language learners, and supporting code switching among speakers of African American English. Exercises for students and examples of student work at all levels are included.
