Anyone – teachers, parents, community members – involved in education needs to grasp these concepts and be able to relate them to their students. Why? Because we don’t know where they’re headed in life.A brilliant blogger with whom I'm acquainted wrote something similar over 5 years ago:
I’ve always felt that education is about preparing someone to pursue whatever they’d like to pursue in adulthood. It doesn’t mean every kid necessarily gets to study every topic that interests him, but he should be equipped with the skills he’ll need to pursue what his school or community might not have been able to offer.
And that’s why we gotta know this, Mr. Sprague. We gotta know it because we don’t have a clue what the students we’re charged with teaching will do after high school.
Bottom line is, I don't know when you're "ever gonna have to use this stuff". But isn't it good knowledge to have, just in case? And why cut yourself off from fields you don't even know about yet? I'll bet the women in school in 1930s Britain never thought they'd be using math to help shoot down Nazi aircraft.Here's a similar example.
It's undeniable that the more education/knowledge they have, the more opportunities they'll have--with or without a college degree. Our business in education is to open doors for children, not to close them.
