We're back from California & will have to catch up. Thanks to Kevin for posting this paper at the link below.
If one plots the numbers from the paper comparing boys, girls, general intellectual ability and processing speed, you can see the dilemma:
Gender-neutral expectations for work performance will disadvantage boys at ages 5-6, 10-12, and 14-19. Developmentally, boys at these ages matched for the same intellectual ability will require more time to process information - which has direct implications for timed tests (including standardized assessments) and assessments of work performance.
Boys are more likely to be grade retained at every grade and they are more likely to drop out of high school. Is the existing educational system developmentally-inappropriate for boys? Sure looks like it...
