Are you thinking of teaching English? The subject is considered by many people to be difficult to teach, as well as learn. Imagine the difficulty to double or even triple if you opt to teach English abroad. There are a lot more considerations to think about, different strategies to use because of the foreign learners, different set of activities to give to the learners depending on their level in English and their age. If you want to learn how to teach English, of course the first thing you should determine is the level of learners you want to teach.
If you prefer to teach children, the approach should be more student-oriented, the environment very relaxed, and the atmosphere should have low affective filter. With children, the more comfortable they are in their environment, the more likely they are going to participate in the discussion and absorb the lessons taught to them. Children also have a more limited schema when it comes to the language, so the examples and activities should be in their level, no matter how “advanced” the lessons may be.
When it comes to teaching young adults to adults, there are different strategies and methods that are more appropriate for their level, plus it would be easier to pick activities that would fit in the lessons for them. However, if you are going to teach English abroad, there might also be a possibility that you will still deal with learners in different levels, regardless of their age. If you're going to be dealing with these types of learners, it's much better if you take additional courses in ESL to help you cope with different types of learners.
