Do you think children should be in a classroom? I tend to believe that children should be outside personally, with very little indoor activity. Even if it's snowing. I learned way more by doing my own thing, what ever that is, then I ever did stuck inside of a class room having a teacher read word for word from a textbook.
I think there are varieties in the aspect of learning to be considered, some don't learn the same way of others. And that should be considered as well.
But generally I don't think attention spans have anything to do with classroom. People were not paying attention in classrooms WAY before cell phones were invented. The problem is the "room" part of a classroom in my opinion.
"I learned way more by doing my own thing, what ever that is, then I ever did stuck inside of a class room having a teacher read word for word from a textbook."
And I learned a lot more by reading stuff from Wikipedia on my own pace than I learned reading textbooks. So, good point.
Are you having difficulty understanding a bestseller book? No worries there, just watch a movie or something.
