I am Polish, I live in Poland, and I found the article's praise for our education system strange. My opinion of it is much lower. I regularly worry about teaching my children to think for themselves — because I believe this is something the schooling system actively discourages. I also don't think that recent reforms did much to improve education, and I don't see why anyone could think they did. I would approach this…
I think that thinking is not something that can be taught, more that it's something that can be encouraged to be learned. In fact, I think overbearing instruction can encourage kids that they don't need to think for themselves. They will be provided the answer, and if they come to a different conclusion, the person with more authority is right.
I remember having a math test graded incorrectly. I knew I was right, I challenged the teacher. I was told that it was still wrong, but the teacher couldn't explain why, the teacher didn't really understand what they were teaching. I brought it home to my parents who also agreed that I was right, but the test wasn't worth enough to get into a fight over.
That experience was one that, if it were repeated, would have hurt my willingness to think critically.
