As a sort of follow-up to yesterday’s post asking about incompetent teachers, a poll on what you might call the “Peter Threshold,” after the Peter Principle. Exactly how many incompetent members can an organization tolerate? The acceptable level of incompetence in any organization (that is, the fraction of employees who can’t do their jobs) is:Market… Continue reading Poll: The Peter Threshold

How Many Incompetent Teachers Are There, Really?
As mentioned in the previous post, there has been a lot of interesting stuff written about education in the last week or so, much of it in response to the manifesto published in the Washington Post, which is the usual union-busting line about how it’s too difficult to fire the incompetent teachers who are ruining… Continue reading How Many Incompetent Teachers Are There, Really?
“Line Plot” is Never the Right Choice (Why Excel Sucks, aleph-nought in a series)
There have been a bunch of interesting things written about education recently that I’ve been too busy teaching to comment on. I was pulling them together this morning to do a sort of themed links dump, when the plot at the right, from Kevin Drum’s post about school testing jumped out at me. This shows… Continue reading “Line Plot” is Never the Right Choice (Why Excel Sucks, aleph-nought in a series)
Poll: Religious Beliefs of Scientists and Science Blog Readers
A big and important argument about religion and science has flared up again on Twittter. It occurs to me, though, that nobody has taken the obvious step of polling people about their actual beliefs, so let’s see if we can’t settle this question with (social) SCIENCE!: I would prefer to be a member of:Market Research… Continue reading Poll: Religious Beliefs of Scientists and Science Blog Readers

Should We Want Students to Go into Finance?
Via Steve Hsu, a GNXP post about the benefits of elite college educations, based largely on a graph of income vs. US News ranking. While the post text shows some of the dangers of taking social-science data too literally (the points on the graph in question are clearly binned, so I would not attribute too… Continue reading Should We Want Students to Go into Finance?
Religious Trivia Contest Results
There’s been a lot written in the last day or so about this Pew Foundation Survey on who knows what about religion. Like most such surveys these days, they have a really easy online quiz version that you can take and marvel that anybody missed any of these questions. My first thought was to just… Continue reading Religious Trivia Contest Results
Now THAT’S a Noble Cause: Restoring Truthiness
Via Tom, the folks pushing for a Stephen Colbert rally on the Mall in DC (because if a clown like Glen Beck can do it, why not an actual comedian?) have found a uniquely useful way to try to boost their signal: encouraging charitable donations: See, anyone can join a reddit or Facebook group or… Continue reading Now THAT’S a Noble Cause: Restoring Truthiness

Teacher Self Management vs. Going to the Dark Side
The New York Times has an article about the opening of a teacher-run school in The City. It sounds like an interesting experiment: Shortly after landing at Malcolm X Shabazz High School as a Teach for America recruit, Dominique D. Lee grew disgusted with a system that produced ninth graders who could not name the… Continue reading Teacher Self Management vs. Going to the Dark Side
