One year on, I still feel the same way.
Find out why I think Widgets is one of the best ELT coursebooks ever, and publishers: PLEASE take a look at that coursebook and try to learn from it!
Even if you can't manage to put this course in front of your learners, as a teacher I really recommend you try to get your hands on the book for your own development. It is Task-Based Language Teaching at its best, and materials design that is genuinely innovative, creative, and enlightening.
