Dear Ed et al OK - just read it for information. It seems like people on the list toss around terms like 'performance grammar' and the rest of us mortals don't necessarily understand what is meant. I feel that this book is a nice introduction. I am not offended or intimidated. I also thinks teachers need a basic grounding in usable and understandable grammar. I also feel that when students finish my class, they can identify, for example, nouns. I don't try to introduce them to more than school of thought. However, I think that at some schools, teachers are asked to introduce various grammatical approaches in courses called 'Modern Grammar' or whatever. Janet Castilleja
