I split this book to create a 2-level pronunciation course for lower intermediate and higher students in Japan. The courses were extremely well received time and time again. The book is an excellent guide for such classes.
I rated the book at 5-stars on its own merit. However, together with the audiocassettes I would have given it four and a half stars, as I believe the audio component needs to be available on CD for cueing purposes and ease of use.
Teachers who have training in teaching pronunciation will probably be delighted with the book. Unfortunately, those instructors trying to use the book without the benefit of proper training in teaching pronunciation may not have the background to utilize it properly.
I didn't bother with the tapes, as I felt it better to use my own pronunciation to model the targets. This allowed me to more easily adjust the speed, timing and rhythm of the exercises to meet the needs of the individual class groups.
Students had an opportunity to practice the targets as a group and then individually during the listen and repeat sections. Afterward, the students generally loved the excellent pair work, which allowed them to further practice and master to some degree what they had learned.
As much as it is a pronunciation course, listening skills are an equally strong component. The pair work was excellent in ensuring each student strove to achieve the listening and production targets.
This book allowed mixed levels of students to work together harmoniously, challenge themselves in a very enjoyable and insightful way, and achieve real gains in their struggles to produce and understand spoken English. Students liked the limericks.
I agree with the other reviewer who stated the diagnostic test with the book is an extremely useful tool ...in the hands of a qualified practitioner.
