So, I've read a lot about the argument between moving through material more quickly (i.e. doing two weeks' worth of work per week) and going more deeply into subjects. However, I've yet to see a lot about just letting kids finish the day sooner. To me, that's the option that is simplest and arguably makes the most sense.
Letting a child finish the day sooner gives him or her a tangible benefit of focusing and working hard: more time to do what he or she wants. Adding more work - either by starting the next week's work sooner or by adding assignments - seems like a punishment for doing well. I feel like it would encourage dawdling.
Cost is an issue with both methods. Parents could easily spend double or more on curriculum each year. That could be financially impossible. It could also cut into the ability to do outside activities like visiting museums and attending theatre or dance performances.
With acceleration, I worry about getting to inappropriate content too soon. I wouldn't want to water down upper-level courses by omitting certain books or topics, but there are books and topics I don't want to use before certain ages. Yes, part of that is protecting innocence, but part of it is simply not being developmentally mature enough for that material (read: I have known a lot of people who start prealgebra in sixth grade and end up having to repeat the course, often twice).
Going deeper only seems like a benefit for subjects of interest, and those interests rarely seem to align with what's being learned (read: she fell in love with samurai at the time we were studying Westward Expansion and with dinosaurs at the time we were studying simple machines). Additionally, I don't want to plant the seeds that all studying has to be done for school; I want to encourage the idea that it's healthy and normal to look into topics just because they are interesting.
- As an aside, I don't like the idea of doing purely interest-led studies because you have to be exposed to something to develop an interest in it. For example, during that study of Westward Expansion, she found her favorite author, Louis L'Amour. If we had just focused on samurai, she may not have discovered him.
I'm obviously in the minority in my thinking, though, so what am I missing? Other than states requiring a certain number of hours, what made you choose to move through the curriculum more quickly or to go deeper?
