I've held a variety of jobs and participated in a range of activities over the last decade, and I've experienced countless orientations that fall all over this spectrum. When I came to Korea in August of 2014 to teach English as a second language, I didn't know where our program's orientation would entail or how much it would or wouldn't help me in my new teaching job. Obviously even within the same orientation everyone's personal experience of it will be different, but here is what I took away from mine:
DON'T EXPECT everyone to be on the same level. There were some people I met that I was incredibly impressed with. One girl spoke gorgeously fluent Korean (and blew away all the Korean co-teachers at our introduction!), and others still had years of teaching experience or were working on Master's degrees while abroad. And others were new, just like me. In fact, you may even meet some people whose qualifications you strongly question, but at the end of the day, take everything as a learning opportunity. Pick up good tips from the more experienced teachers and learn what not to do from those who set bad examples. You have control over what kind of teacher you want to be!
DO EXPECT to meet some awesome people. Not only are you all in the same boat, but that boat is floating in a foreign sea, and you're all feeling equally out of place. Orientation sort of feels like being a freshman in college all over again--friend groups are formed, everyone is a little awkward and out of their element, and no one wants to seem like they don't know what they're doing. But everyone is new to something--whether it's teaching, or Korea, or both. Orientation is a huge opportunity to make friends...and go visit them in their respective placement cities later!
