The real value in having native speakers (for any language) is that they live in the language and don't regard it as a set of grammatical rules to be navigated and vocabulary to be built up. They also have information that can be useful that even the most impressively fluent second language speakers lack.
On the other hand, most native speakers function best when dealing with more advanced students who are more likely to benefit from the particular knowledge they have (and students can also benefit from the knowledge the native speaker doesn't have). But sending out a native (with no command of Polish or real knowledge of how things work in Poland or how most Polish people learn) to work with beginners is ..... not wise.
ABRUPT CHANGE OF TOPIC CAUSED BY StOOPID FORUM POLICIES ABOUT DOUBLE POSTING!!!!!
(wish i was the same about Polish but i just cant grasp it)
I don't buy it. You're just being lazy.
Just remember the less Polish you know the more defenseless you are and the more dependent you are on the mercy of people like your boss....
Lack of interest is no excuse, sit down with your textbooks and make the effort and the interest will come.
Plus you set a horrible example for your students and colleagues. How are they supposed to respect you as a language teacher if you're incompetent at language learning?
