I’d have done just about anything for a “work to earn back X” system when I was in high school. I think that plan has some real merit.
The moment we started bringing home letter grade report cards is when my parents told us that if we ever brought home a “C” on a report card, we’d be grounded until the next report card. This was in late elementary school for me, and I think started at middle school for my sister (we moved), and that meant the grounding typically lasted nine weeks, or a full quarter. Unlike Harriet the Spry’s experience, my parents were perfectly willing and able to enforce this rule for the full nine weeks, including birthday parties for friends or ourselves and all the other really big stuff. I won’t say we never had an exception for one of those things, but I can’t remember it if we did.
“Grounded” always meant one thing in my childhood. Access to nothing. No TV, no phone, no going out with friends, no sports, no after-school drama. When the internet came along and I became an IM addict, no computer except as needed for schoolwork. If we’d had iPods and the like, you can bet your ass that would have been gone too.
My parents were understanding of the fact that some subjects really are a challenge for some people. While it started with “if ever a C”, it morphed over time to, “if ever a C in a class we know you can do better in”. So that C I got in Calculus my senior year didn’t cost me, nor would have the C in Geometry my sophomore year had I not also gotten a C in Algebra II. They did make it very explicitly clear it was for the Algebra class, and not the Geometry class I’d been struggling with all year.
I think they had good intentions, and it worked on me. I never got two consecutive report cards with Cs, and I stayed grounded when they grounded me. It worked less well on my sister, but she’s more blatantly willing to go toe-to-toe with someone. Still, I remember it as far too harsh a punishment, in that it was unrelenting and there was no chance to demonstrate that things were really doing better until nine weeks after the “problem”. Sometimes I wonder if my sister would have taken it better, herself, if there’d been a shot at less pressure sooner. I am certain I would have - my parents and I (especially my mother and I) had a huge number of truly epic fights when I was a teen.
Anyway, I would say that this is an example of a good idea gone awry. Their idea was that it wasn’t the stuff in the middle that mattered for college admissions and scholarships, it was the report cards, and that’s why there was no relenting even if things came back better in the middle. As I recall, there was also very little parent to teacher communication, and perhaps that would have helped. I do think, though, that being willing to allow a “earn back X for Y results” would have gotten the same improved overall grades with less anger and tension in the house. And, of course, if the grades had slipped again when “X” came back, it would have been more obvious (to me, at that age) that there was a case for “X” distracting me from my work.
