“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)

Thus, the traditional Uncertain Principles Nobel Prize Picking Contest: Leave a comment on this post predicting the winner(s) of one of this year’s Nobel Prizes.

Teacher Evaluation and Test Scores, aleph-nought in a series

There’s been a lot of energy expended blogging and writing about the LA Times’s investigation of teacher performance in Los Angeles, using “Value Added Modeling,” which basically looks at how much a student’s scores improved during a year with a given teacher. Slate rounds up a lot of reactions, in a slightly snarky form, and… Continue reading Teacher Evaluation and Test Scores, aleph-nought in a series

Grenade Tossing About Grade Inflation

Via Thoreau, a paper from a physicist in Oregon that’s pretty much a grenade lobbed into the always-explosive grade inflation discussion: We use four years of introductory astronomy scores to analyze the ability of the current population to perform college level work and measure the amount of grade inflation across various majors. Using an objective… Continue reading Grenade Tossing About Grade Inflation

Science v. Religion: Time to Try (Social) Science

There are lots of reasons why Josh Rosenau is one of the few writers blogging about science-and-religion issues that I still read. This morning’s post on what you ought to do to determine effective approaches is an outstanding example: Rather than looking at national polls, which are crude instruments and can miss shifts within small… Continue reading Science v. Religion: Time to Try (Social) Science

I Write Like a Random Selection of Famous People

Via Crooked Timber, there’s a silly web site that lets you put in a chunk of text, and does some sort of statistical analysis of it to determine what famous writer’s prose it most closely resembles. It turns out, I’m kind of hard to categorize. For instance, when I’m writing about Holy Grails, I apparently… Continue reading I Write Like a Random Selection of Famous People

Faculty Evaluation Is Really Complicated

There’s a paper in the Journal of Political Economy that has sparked a bunch of discussion. The article, bearing the snappy title “Does Professor Quality Matter? Evidence from Random Assignment of Students to Professors,” looks at the scores of over 10,000 students at the US Air Force Academy over a period of several years, and… Continue reading Faculty Evaluation Is Really Complicated

Academic Poll: Talk or Poster?

The Steinmetz Symposium is today at Union, as mentioned in yesterday’s silly poll about fears (I love the fact that “Wavefunction Collapse” leads “Monsters from the Id” by one vote at the time of this writing– my readers are awesome). As a more serious follow-up, there were two presentation options offered to the students, and… Continue reading Academic Poll: Talk or Poster?

Non-Dorky Poll: Vote Reporting

As James Nicoll is fond of saying, context is for the weak. So here’s a context-free poll regarding the reporting of election results: Releasing a rank-ordered list of candidates with vote totals after a contested election is:online survey If you’d like to explain what context you might imagine this to have in the comments, that… Continue reading Non-Dorky Poll: Vote Reporting
