The Mexican children learned English the way babies do, only faster, through total immersion. Slow learners and average students, after all, do not necessarily learn less than gifted students.

While I m at it, the idea that all our gifted students will be future leaders or discoverers or inventors, etc. is ludicrous. Their intellectual gifts offer no guarantee of their goodness or effectiveness as human beings. Surely we can find ways to tailor education to challenge academically gifted children without separating them entirely from their peers. Surely we can individualize the curriculum even as we keep them with a peer group that is representative of the real world which is, after all, where they will have to function when they leave school. All children need lessons in humility and compassion and respect for others, and none need those lessons more than do our academically gifted children.
