Economic Astronomy II: Gender Shares of Jobs
Posted by Chad Orzel on August 10, 2011 The other big gender-disparity graph making the rounds yesterday was this one showing the gender distribution in the general workforce and comparing that to science-related fields: This comes from an Economics and Statistics Administration report which has one of the greatest mismatches between the tone of the headline of the press release and the tone…
Being Educated Is All About Half Guessing
Posted by Chad Orzel on July 20, 2011 Keeping the week’s unofficial education theme, Kevin Drum posts about the latest “kids these days” study, namely the just-released NAEP Geography results. Kevin makes a decent point about the 12th grade questions being fairly sophisticated, but includes one comment that struck me as off base: I gotta tell you: I went through the five sample…
Reforming Education: Bonuses Aren’t Enough
Posted by Chad Orzel on July 20, 2011 One of the standard education reform proposals that gets suggested every time somebody brings up the condition of American public education is that teachers should be offered some form of performance incentive, whether in the form of “merit pay” programs on a continuing basis, or bonuses for reaching particular targets. This is one of those…
Grade Inflation? Blame the Baby Boomers
Posted by Chad Orzel on July 19, 2011 A lot of pixels have been spent discussing this study of grade inflation, brought to most people’s attention via this New York Times blog. The key graph is this one, showing the fraction of grades given in each letter category over the last fifty years: Lots of effort is being put into trying to explain…
Great Moments in Deceptive Graphs
Posted by Chad Orzel on July 10, 2011 This morning, via Twitter, I ran across one of the most spectacular examples of deceptive data presentation that I’ve ever seen. The graph in question is reproduced in this blog post by Bryan Caplan, and comes from this econ paper about benefits of education. The plot looks like this: This is one panel clipped out…
Neither a Neuroscientist Nor a Statistician
Posted by Chad Orzel on May 31, 2011 A bunch of people I follow on social media were buzzing about this blog post yesterday, taking Jonah Lerher to task for “getting spun” in researching and writing this column in the Wall Street Journal about this paper on the “wisdom of crowds” effect. The effect in question is a staple of pop psychology these…
Is College Worth It?
Posted by Chad Orzel on May 17, 2011 As I noted the other day, we’re entering graduation season, one of the two month-long periods (the other being “back to school” time in August/September) when everybody pretends to care deeply about education. Accordingly, the people at the Pew Research Center have released a new report on the opinions of the general public and college…
On the “Hot Hand” in Basketball
Posted by Chad Orzel on May 9, 2011 A little while back, Jonah Lehrer did a nice blog post about reasoning that used the famous study by Gilovich, Vallone and Tversky, The Hot Hand in Basketball (PDF link) as an example of a case where people don’t want to believe scientific results. The researchers found absolutely no statistical evidence of “hot” shooting– a…
Education Reform Is Slow
Posted by Chad Orzel on May 3, 2011 Kevin Drum notes a growing backlash against education reform, citing Diane Ravitch, Emily Yoffe and this Newsweek (which is really this private foundation report in disguise) as examples. The last of these, about the failed attempts of several billionaires to improve education through foundation grants, is really kind of maddening. It makes the billionaires in…
On Multitasking
Posted by Chad Orzel on April 21, 2011 After chasing a bunch of kids with cell phones off of his lawn, Kevin Drum has kicked off a discussion of “multitasking”, specifically about whether it’s merely a threat, or a positive menace. He points to an interview with Clifford Nass, a researcher who says his experiments show that nobody is any good at doing…
