Unpopular opinion: If we have evidence that shows that keeping all the smart kids in one group creates massively better outcomes for that group, then that's something we should be doing everywhere, not something we should ban.
I continue to believe that gifted kids are special needs kids, and that they shouldn’t be in the same classroom as those who are struggling for all of their classes.
People don’t like to talk about gifted kids, except to imply that being “too smart” is somehow bad or unfair, and I think it does them a disservice.
Gifted kids get very, very bored, and lose interest quickly, when they aren’t challenged.
