Wouldn't it be nice if kids really did mature in lockstep with each other? Then all those graded curricula and "What your Nth Grader Needs to Know" would make sense. Unfortunately, kids, particularly gifted kids, don't even mature evenly within themselves, much less in step with their peers. This is true for neuro-typical (NT) kids, too, but I think gifted kids have it particularly bad.
Maybe I just feel this way because I've got two who are twice-exceptional (2e). Klaus is going in for another round of neuropsychological testing tomorrow morning because we (his grownups) all agree there's something wrong with him, but nobody seems to know what it is. ADD, anxiety, depression, bipolar, perfectionism, OCD, eye-teaming issues, all or some combination of the above? Who knows?
Xavier is probably back at or slightly above grade-level on math and writing, but I'm still hesitant to plunge him into a high school class for fear of setting him up to fail. Even Wolfie can comprehend and write at an upper high school/early college level but the upper high school work requirements, in terms of what is due on a weekly basis, are a huge burden for him.
So, what to do when the ability to comprehend far outstrips the ability to produce? If we pour as much into the little brain as it can hold but don't expect commensurate product, is that not training them to do as little as necessary to get by? Just what is the cosmic point of being able to learn more and faster than you can produce?
