Query: Do not use outside of USA

As a Peace Corps volunteer part of my duties are to teach English to my community. I purchased this book because I have little background in teaching. I had hoped this book would give me meaningful guidance. It fell far short of this.This book was designed with a very ethno-centric point of view. The pictures are of things most Americans would be familiar with but when I tried reviewing the pictures with some of the Thai people in my community they had no idea what the objects were in either language.Most of the pictures are crude and get worse if you try to reproduce them. The entire idea of a book like this is to provide reproduceable study material, otherwise what is the point?If you are in my situation, teaching to people outside of the U.S., Then this book is not for you.
