Query: This book is awful!

I was assigned to read this book for an education course this summer. The title would suggest that this book would be very useful for new and inexperienced teachers. I was extremely disappointed. Jesness rarely, if ever, explains the research behind his opinions in this book. [...]. He makes huge generalizations and gives an erroneous lesson plan trying to use the SIOP model. The worst moment in the book is where he says that ESL teachers would be justified to just teach English to English Language Learners and not teach the content areas, despite the fact that all ELLs are required to take content area exams under NCLB. There is so much rich literature to help teachers instruct ELLs, but this book is neither rich nor useful. I would highly recommend NOT reading this book.
