DY: And then what? Does that mean you should hold them back and prevent them from achieving as much as the smarter kids? Besides, weaker students don’t always benefit from only being in a class with weaker students- you have to deal with all kinds of people in your life. The same goes for the stronger students.
And remember, Gladwell’s theory is about physical development, in which case it makes a lot of sense that a kid who has 6 more months to grow would be bigger and bulkier than a younger kid. But plenty of smart people were born in July and on- in fact, chances are, it’s pretty close to 50% (if you comb through the records and it’s significantly different, MAYBE we’ll talk).
