Have you discovered the Cambridge University Press ELT Teacher Support page yet? It has a number of free booklets written by familiar names in ELT such as Jack Richards, Judy Gilbert, and Michael McCarthy. There is also a presentation from Jack Richards as well.
Each booklet has valuable tools based on solid research that will help teachers at all levels. I would recommend spending some time going over this material. It may just help you in your lesson preparation.
Have you used this material before? Was it helpful? Do you have any other links to add on pedagogical material that may be helpful?
