I have many friends from when I was living in Asia that were school teachers when I was there. Japan, China, Korea all do it. Most of the teachers tend to be young graduates who are still trying to figure out what they want to do, or they are just wanting to get away from America (other countries too), When I say America I mean school, parents, responsibilities, etc..
In Korea, most don't do it for too long, met a couple that married a foreigner and stayed for that. The pay for all countries are abysmal. 1500-2000 USD per month, housing is normally provided, but as expected not much. A lot of teachers take side gigs giving private tutoring lessons. It is very important for parents to get their children speaking good/fluent English to pass the TOEFL and try to get into an American/English university. An American education is highly prized in Korea. There are a couple of prestigious universities, then after those, it looks better to have an American degree. When I was there I taught some high schoolers (not for cash compensation), but was given an award for it. Not reward, an award.
So hagwans (private english speaking schools) are looking to make contracts for teachers. They can and do have an undergrad in anything. They don't want them making lesson plans or anything like that were they teach from. The education plans tend to be very rigid. In some instances where Americans were allowed to teach what they wanted it didn't always turn out well. Culture, etc.. An example, "Everyone get into groups of 4, we will do an exercise" "I want each of your group to come up with a name and genre for a pretend movie that you make up."
1. They were scared to break into groups on their own since they were not assigned, wasting time.
2. They didn't completely understand the assignment because the idea was so foreign to them. They were afraid to speak up and ask.
3. Later, when they did come up with an answer,every single one of them sounded the same like this..
"Group 1, what do you have?"
"We have Rambo 9, an action movie!"
"Ok what happens in it?" (The exact same as the recent Rambo)
"Group 2, what do you have?"
"The Terminator 8"
"Ok, what happens in yours?" (The exact same as T2)
You get the idea.. not that many original thoughts.. The Asian bosses seem to like working from workbooks, etc..
K-pop and their choreography is something original and amazing, so there's that.
Private tutoring, can be more profitable. Almost all of my buddies did private tutoring on the side and they found it easier to teach. Some students can be frustrating, but the teacher gets to teach what they want in most instances.
I haven't lived in Korea in almost a decade, but went on a month long trip about two years ago. I doubt much of the teaching system has changed since then.
A lot of American teachers say they were meaning to save their money while they were there. Not too much of that was happening from what I was seeing. We hung out at a lot bars and restaurants.
One of my buddies did some youtube videos about teaching in Korea. You can look at youtube for those. Another did several for southern China.
If you daughter just wants to take a "break" following graduation and escape to asia for a year or two that is one way to do it.
She wont get rich, and there are some things she won't like, but she will be better traveled..
Employment is pretty easy and straightforward.
