Education is always a very interesting topic to me, of course. Why do we learn things the way we do? Because that's how people in the generation before us learned them, in general. Sometimes you wonder, how were things done way back?
For example, how was math taught many years ago? Here's how the Mayans did it. It's really interesting and I am still trying to wrap my head around it at the moment.
Thanks to Catalina for the heads up!
