SF Parent:
That is partially what I worry about as for grade acceleration. Also, I just realized it the other day, one of those 'aha' moments....when we accelerate our different/strange/bizzare/gifted children through the grades, they end up being in the class with exactly the same kids, just older. 4th graders are not smarter than 2 graders, they are just older . I so stronly believe that PG kids should be grouped togehter, this would probably facilitate an experience of a lifetime. Why do they like so much summer programs for the gifted? Because that meet they intelectual peers, not older children.
I also think that learning should be broadened as much as possible for those kids, not necessarily pushed forward. Having said that, I am still a mother of an 11 year old who is taking geometry :-) and am just fine with that.
