Most American students would run kicking and screaming if you told them they had to attend Saturday school. It’s quite the norm in Korea, though. According to a quick (unofficial) survey of most of my students, most all of them attend school on Saturdays, for half days, and they are completely ok with it. They are actually a little upset that Saturday is being taken away from them.
It’s a pretty well-known fact that the Korean president is not well liked. One of the main reasons is that he is trying to streamline the Korean education system to make it more like the American education system. The primary reason for that is because in a recent study, Korean children were named the least happy (or second to least, I can’t remember) in the world. They spend too much time studying, and not enough time being kids. I put this statistic in the same category as the study that said that Orlando is the angriest city, and St Louis is the most dangerous. While it’s the president’s job to not dismiss such reports, I take them with a grain a salt.
