I think that, while they make a good sound bite, those generalizations depend on the kid.
In my experience, not all kids hit their academic stride “on time”–ie, by the start of high school. So many kids simply don’t do well in high school, only to hit the right college and soar.
So, no, I don’t want my pilot or my surgeon to have been a C student-- in med school or pilot school. But I’m honestly OK with the idea that he struggled in high school English or Geometry-- as long as things improved in college.
The reality is that the vast number of kids I’ve taught over the years-- even those A+++ students who tend to populate this site, won’t remember much of the math I’ve taught them. Unless they use the Precalculus, the work we’ve done this year will suffer the same fate as the State Capitols they memorized when they were 8. But I’m hoping that I’ve helped teach them how to learn.
Speaking of generalizations, here’s one: Lots of B and C high school kids learn that. Academics don’t come easy to them; simply showing up, paying attention and doing the homework doesn’t get them the same rewards it gets some of their luckier classmates. They’ve got to work longer and harder to achieve less impressive results. They’re not into grade grubbing; they’ve learned long ago that they’ve simply got to put in the time, get extra help, practice and practice some more. And I think those lessons will serve them well in college. And, far more importantly, in life.
To put it into local terms: I grew up as a NY Mets fans. Now, if you’re a New Yorker, you know how difficult a path that is. Being a Yankee fan is so much easier: you root for your team and they win. And win. And win. But that’s not the fate of Mets fans. We’ve got to have heart, to believe (to quote Tug McGraw) and keep at it, year after year, even when you don’t get the results you want.
Many (nope, not all) B and C students are like Mets fans. They hang in there, test after test, even when they don’t get the results they need.
And every once in a while, they win the World Series. But in the meantime, they learn something from the effort they put in.
