As part of our curriculum, we have these newspapers (which are presumably level-appropriate current-events newspapers that the kids can read, and from which we get many of our debate topics). I actually rather like the newspapers, despite their many mistakes, as the kids seem to get into actually being able to talk about relevant current events in class. I had a funny experience, however, recently. And some of my students actually "got it" when I pointed it out to them.
You see, with the newspaper comes a workbook, which includes some pages of difficult vocabulary to review. At the top of the page, it says, "반복 학습을 통해 반드시 암기하고 Reading Comprehension과 Writing을 통해 그 쓰임새를 학인합시다." (rough translation: blah blah memorize these words blah blah")…. Then, farther down, in the list of vocabulary words to memorize, they give this word with its example sentence: "proficiency 숙달, 능숙 example: Pushing children to memorize vocabulary or grammar rules will not lead to a high level of language proficiency." This is subversively hilarious.
