The world is a bell curve. Classroom test scores, employee performance in a company or how many people really, really like you. No matter the population you're studying, they always fit neatly across the standard deviations of the famous bell curve.
Increased physical activity during the school day can help children's attention, classroom behavior, and achievement test scores. Meanwhile, the decline of play is closely linked to ADHD; behavioral problems; and stunted social, cognitive, and creative development.
If you think dealing with issues like worthiness and authenticity and vulnerability are not worthwhile because there are more pressing issues, like the bottom line or attendance or standardized test scores, you are sadly, sadly mistaken. It underpins everything.
I am a product of affirmative action. I am the perfect affirmative action baby. I am Puerto Rican, born and raised in the south Bronx. My test scores were not comparable to my colleagues at Princeton and Yale. Not so far off so that I wasn't able to succeed at those institutions.
I was always told that I was good in mathematics, and I guess my grades and standardized test scores supported that. My worst subjects were those that generally involved a lot of reading - English and history. So, having good test scores in math and mediocre ones in reading, I was naturally advised to major in engineering in college.
Second, when comparing private school and public school test scores, it's like apples and oranges. Public schools have to take everyone, but private schools can be selective. It's not accurate or fair to compare the job they do.
With my academic achievement in high school, I was accepted rather readily at Princeton and equally as fast at Yale, but my test scores were not comparable to that of my classmates. And that's been shown by statistics, there are reasons for that.
Scientific research and other studies have demonstrated that arts education can enhance American students' math and language skills and improve test scores which in turn increase chances of higher education and good jobs in the future.
I don't regard the fact that there's a disparity in test scores nearly as importantly as I do the need for diversity, because I know from long experience that test scores, though useful, are a very limited measure of things that matter in choosing students.
If you improve education by teaching for competence, eliminating schooling, and connecting with students, the test scores will improve.
