Good Basic Info and Supplemental Aids

I'm an experienced teacher and have a Masters, but have never taught ESL. I'm going to Asia and thought a TESOL certificate might help me pay for the trip. The first 1/3 of these lessons are well structured for students with little or no teaching experience in any field. But, beginning with lesson 5 to the end, I learned key words and important strategies specific to teaching non-native English speakers. There are also numerous supplemental teaching aids offered for those of us building a curriculum from scratch.
