So here's the thing. I'm not a big supporter of Jeb Bush, usually. I'm not so sure that's the case in this specific instance. Quick overview, Jeb wants to start having high schoolers declare a major.
Schoolers? Is that right?
"You know what? There is no Easter Bunny! That over there's just a guy in a suit!"
Ok. Back to the task at hand.
On the one hand, this could very easily turn into a lot of stress for a lot of kids, mostly in pressure from parents who want their kid to be a doctor, and so force the young'n to major in bio or, if they're particularly awesome, chemistry. And that's not good times.
On the other hand, I think that students should be allowed to self-design their curriculum as long as certain minimum criteria are still being met. I like the concept of having to have a minor, so long as that minor is in a field disparate from that of the major. I really do support the concept of a liberal arts education, and think that I benefited from having to go through all of that German/Econ/Psych junk at Allegheny. I disagree with Jebuchadnezzar that this'll stop, or significantly decrease dropouts, but I'll let him have that. If implemented properly, I don't see how it would be much different than the already existing vocational programs, except that it would allow kids that are really into chemistry study more chemistry, those that are really into english focus on that and those that are really into machining work on machining.
Then again, college students can be really stressed out, and many probably don't need that extra pressure. Those that are really driven to study whatever are going to do that regardless of whether there's an actual system designed for them (and they shall weep when I fail them on their lab reports, and such), and they might be successful at that (e.g. R. B.) or they might have an anyeurism, but that's independent of what's going on here, I think.
Final Verdict: Interesting experiment. You Floridians tell me how you like that.
