Teacher Discussion Forums

It's time for me to submit my requests for department materials for next school year and I'd like to add some teacher resource texts on the teaching of English pronunciation. Here are two titles I saw in a recent catalogue from Cambridge:

Teaching Pronunciation: A course book and reference guide by Marianne Celce-Murcia, Donna Brinton and Janet Goodwin

Pronunciation Practice Activities: A recource book for teaching English pronunciation by Martin Hewings

Have you read these before? Do you find them accessible and practical? What other sources could you recommend?

Thanks,

Kt
