Keith Clay
Room 323
sabbatical
What I had planned:
Calculus Physics

Statistics with AIP
K12 Schools
What really happened:

What “Statistical Research Center” of “American Institute of Physics” does:
They are statisticians (not physicists) They collect data about physicists…
…and other scientists… and science education. Physicists make up their Advisory Council They study: jobs in industry… education…
high school teachers… grad schools… community awareness… and…
Ethnicity, Gender, and the Physics Community
Results from the Statistical Research Center of AIP
(Humbly reported by Keith Clay of GRCC)
Why should we care about women and minorities in physics?Race and gender equity in physics is awful.
Could this teach us about other equity problems? Could physicists be an “indicator species”? What should we tell our young girls? Our black
and Latino children? Can we figure out how we’re failing? Is the situation hopeless?
Success or failure in physics influences success in many other fields.
DISCLAIMERS
1. I am a white male.
2. I am not a statistician.
3. I did not collect the data.
4. Statistics can only hint at causes.
5. As an advisor to SRC@AIP I would gladly relay suggestions to AIP staff.
GENDER: Part OneAre women “less able”?
Earlier this year…Harvard President Laurence Summers:
Perhaps we should investigate whether women are innately less able than men in math and science.
(paraphrased: the exact quote is not available)
GENDER: Part OneAre women “less able”?
Consider the case of Rachel Ivie Becomes Experimental Psychologist. Emphasizes statistical research. Takes a job with SRC at AIP. Dec. 2004:
Authors study on women in physics. Prepares for long winter’s nap.
Jan. 2005:Summers makes
asinine statement!The next day:Time, Newsweek, NYT, Washington
Post, and NPR descend on AIP!
GENDER: Part OneAre women “less able”? The best conclusion of the SRC@AIP... … based on all available data… … after months of investigation…
“no”
GENDER: Part TwoAre women less successful?
Do women fail or drop-out more than men? Is discrimination statistically visible? None of this data comes from pre-high school Most of the data is in physics All of the data is in academia
GENDER: Part TwoAre women less successful?

GENDER: Part TwoAre women less successful?
They have fewer numbers, but… On average they succeed (about) as often All trends are positive (except comp. sci.) “Upper levels” mirror earlier “lower levels” The “Leaky Pipeline” doesn’t leak much We’re now at 46% in high school
ETHNICITY: Do “equal skills” lead to “equal success”?Preamble:
Using self-identified ethnic classifications…
Observations on math and science: Average performance of Caucasian and
Asian Americans is at one level. Average performance of African and Latino
Americans is at another.
When (maybe why?) do differences appear?
ETHNICITY:How can we judge equal skills?

Obvious question: why are Latinos less successful than African-Americans?
Easier question to answer:
What helps African-Americans to succeed?

What inspires African-Americans who succeed in physics?When asked for top 3 sources of inspiration…
40% refer to an African-American teacher of a subject other than physics
20% cite inspiration from a white teacher Very few cite a white physics teacher.
Even at HBCU’s, most never seean African American physics teacher.
Pseudo-Conclusion
There are no definite conclusions. These studies are ongoing. AIP has accepted a huge research
grant from NAS so expansion into new research areas is unlikely in the immediate future.
And what about Green River? According to the American Association of
Physics Teachers 2005 report, SPIN-UP TYC: Best Practices of Physics Programs
“GRCC has strong minority and female student enrollments in all of its physics courses… GRCC has very high retention rates… students have performed extremely well on national assessment.”
We have no idea why, except…“The use of inquiry methods in all physics classes has
led to greater student retention and understanding.”
