It depends what you are looking for and who you are teaching. But if you are new to teaching then you probably do not know what to look for. And they all start to look the same.
Here is one I think is a little different. It is called TEKA. I have been working on it over the years. It is very visual and uses a lot of how-to videos shot in the classroom. It is focused more on teaching kids and there is a good deal of exchange and feedback in regards to your lesson plans.
Basic stuff...
What are you going to do in that classroom?
How are you going to handle problems when they arise?
I think this is better for the person who wants to learn. For the person who wants to improve their teaching. I think lots of people take courses before they teach abroad, but I think it is actually better to take one after you start.
