Mrrzy:
I observed no religious-related content, nor religious discussions in my school years, nor none in my childrens schools.

However, I did observe that the local education system did a poor job of preparing students for science related careers, which I suspect would have an impact on some students considering future careers in science. In biology, information on human evolution was presented, with no related religious discussion.

What seemed puzzling to me in school was how my early grade history classes tended to show a strong western bias (mostly pro British and USA) in history, wars and governing systems- and little to explain the perspectives of the other sides. My recollection is educational materials related to socialism and communism were more akin to propaganda-versus descriptions that stimulated a students thought processes. But, this may have changed since, and, on reflection, may have been influenced by the cold war period when I was in school. Additionally, the material may have mirrored the perspectives of the societies where the books were published, which were mostly not local?
