School days should only be extended that much if they drop homework, drop the number of school days by a third, and fix the system.
Extra time spent in school won't help kids learn more if they don't give a squirrel's bloody half-wasp-eaten corpse about the material. None of the boring stuff they taught stuck past a test because I didn't care until a couple years later or earlier. In 6th grade science, I wanted to learn about space and physics. I learned about rocks and sediment. 7th grade, I actually started getting interested in rocks. I had to learn about life. 8th grade, and now life seems interesting... but I have to learn about space and physics, which I lost interest in the year before. Making things worse, as soon as I started to grasp a concept, I was forced to drop it and move on to the next one.
Why aren't we taught more about just getting through life in school, anyway? Learning about rocks should be something to do in your spare time. I should learn to cook or learn how to handle emergencies in school...
You know, I think I'll link to this old post of mine. (It's the wall of text, of course.) It's relevant. Seriously, could anyone stand three more hours of that?! Plus, besides those "No touching anyone ever, be on time or else, nothing offensive at all, etc." rules, the "No bathroom during class" rule would be painful. They always tell you to go at lunch, and you do, but you also drink and eat at lunch, and an hour or so later you have to go again. It's amazing how a life science teacher can't understand peristalsis. The three hours better include an extra lunch break.
Ergh, mind numbed. Can't type.
