As a professional EFL teacher it is probably a good idea to subscribe to some of the many journals and magazines available to the industry. It also probably pays to belong to one of the professional bodies such as IATEFL. Or does it? I belong to IATEFL and also take the Voices journal, ELTJ and English Teaching Professional. I find these mostly interesting and often helpful but I wonder if in the age of forums, blogs and twitter if these are still worthwhile and worth the money.
I think, personally, that on balance they probably still are but I would be interested to know what journals (if any) you read and if you belong to any of the professional bodies. It would also be interesting to know if you find them valuable or not, and what would you recommend to fellow teachers?
