I heard it on NPR and they don't lie!

...the researchers got two sets of math test scores. One set of scores were given by the classroom teachers, who obviously knew the children whom they were grading. The second set of scores were from external teachers who did not know if the children they were grading were either boys or girls. So the external teachers were blind to the gender of the children...

...find that the classroom teachers tend to give the girls lower grades in math than the external teachers, and they give the boys higher grades.

The listener comments are running about 80% bashing the story for shoddy reporting.  This groundbreaking study is so awesome that NPR didn't link to it and you have to pay to read it.

One comment
The "biased" and "unbiased" scorers were not grading the same exam (as pointed out by Rational Discourse). Also, there is no detail as to what questions were in each exam or whether the students were required to show their work in arriving at each answer.

ETA - Study was on 6th graders.

Either 2 + 2 = 4 or it doesn't!

Did they say what they were marking people down for?  Showing your work?  Partial credit?

Will the mathematicians in here please let me know, am I crazy?  Either an equation is correct or its not, right?

I know the math is shoddy when I hear "I've only been with 2 or 3 other guys".

Didn't listen to the report because of the "shoddy reporting" comments, so I don't know what level math we are talking about here -- any form of math from algebra or higher you will be graded on the work process, so much so that the wrong answer due to an arithmetic error will not detract as much as the wrong answer from a logic error.

Seriously, thank you for the clarification.  Never took any college level math.  I figured it would have to be something like that but it said "children".  I wasn't picturing Trig or Calculus, though I guess it could be.

yes partial credit is normally awarded, but In calc and stats I never had points deducted for partial work and the correct answer.

Study was on 6th graders.  Not exactly doing calc at that age.

Could be doing algebra.

It is more important that you grok the Distributive Property and somewhat forgivable if you have a brain fart and calculate 3 + 3 = 9.

Oh look the entire "study" was from a single school system in Tel Aviv, I'm sure that's a representative sample of the entire world.

OK, the transcript was a very short read and the comments are really telling.

In short, what was described by NPR was not how the study was actually conducted, and the study itself has fundamental flaws.

The other problem I had with it is that it started following the kids in the 6th grade, which is when girls start doing worse.  But in the lead-in it talked about how girls do better than boys in grade school.  the researchers seemed to assume that the grade school performance was the desired outcome, and the falloff in girls scores was the only problem, NOT why boys do shitty in grade school to begin with.
