This book has been used in language methods classes for many years:
Shrum and Glisan
"Teacher's Handbook: Contextualized Language Instruction"

They keep it updated, but I have an earlier version.

Here's a note from the Alibris website about it:

   Teacher's Handbook presents a concise theoretical review followed by
   provocative case studies that ask new and experienced instructors to
   judge for themselves how best to acquire ESL and foreign language
   proficiency. The Teacher's Handbook also includes extensive
   appendices covering professional organizations, publications, and
   performance standards. This new edition includes a book-specific web
   site that contains video case studies, a bulletin board, and useful
   links to a variety of professional organizations and mailing lists.
