at the relationship between scores on what is called the Trends in International Mathematics and Science Study, or TIMSS (math and science tests given every four years to children in many countries around the world), and month of birth. They found that among fourth graders, the oldest children scored somewhere between four and twelve percentile points better than the youngest children. That, as Dhuey explains, is a “huge effect.” It means that if you
Note: so then the question becomes how do international age cutoffs for schools impact rankings on this test.
success? Because we so profoundly personalize success, we miss opportunities to lift others onto the top rung. We make rules that frustrate achievement. We prematurely
Note: this is fascinating...by failing to consider the impact of other factors besides individual effort we waste the talent of others. this would be particularly true of places like middle schools where comparisons are easy between large gropus of develpoing students.
Schools could do the same thing. Elementary and middle schools could put the January through April–born students in one class, the May through August in another class, and those born in September through December in the third class. They could let students learn with and compete against other students
Note: do this....compare birthdates against honor roll students and see how performance compares against the cutoff.
