Intended for preservice and inservice teachers at all educational levels, but especially for those in English education classes, this book examines the foundations of grammar instruction and supplies some definitions and examples of grammar usage. Part one of the book explores relevant language research, reasons for teaching grammar, the psycholinguistic nature of language processes, and ways to assess and assist students in their reading and writing of the English language. The second part of the book is essentially a grammar handbook, discussing the principles of grammar in three contexts: as product, according to the traditional and structuralist viewpoints; as process, reflecting the attitudes of transformationalists; and as a guidebook, helping writers to learn certain conventions of mechanics (in this particular case, the punctuation of clauses and their reductions).
